The Weapon R Secret Weapon Intake kit is our favorite short ram intake kit on the market! This intake system is a result of countless hours of testing and tuning of air intake velocity, air mass and air speed for each vehicle application. The result is an intake system that performs better than any cold air intake, but with a short ram. The handsome intake features a 1 million mile limited warranty air filter, quick and easy direct fit installation, all parts necessary for install, and the best horsepower per dollar performance bargain!
This unique intake system utilizes its own velocity stack that is isolated from the heat generated by your engine. This isolation technique provides an exceptionally colder intake charge and raises overall performance and efficiency. We here at Pro Street typically see gains anywhere from 4-9 wheel horsepower using this intake system. Turbo or Supercharged vehicles with forced induction may have more of an increase than that.
We use this Secret Weapon intake on our 450 horsepower Lancer Evolution 8, and recommend it to all of our customers - especially customers with no prior modifications who want to increase horsepower with no hassles, no driveability issues, and experience that awesome intake suction sound! Look below for horsepower gains on popular vehicles. Unlike other intakes, these intakes increase power through the full power band!
These intakes are in stock, and ready to ship.
Weapon R Intakes from Pro Street provide direct fit installation, reusing all your stock sensors. This is a complete bolt on kit, requiring no modification, and providing added horsepower!
The Secret Weapon Intake Systems is an result of countless hours of testing and tuning of air intake velocity, Airmass and Airspeed for each vehicle application. The Result, an intake system that performs better than any Cold Air Intake, but with a Short Ram. It is possible by Weapon*R's Patent Pending Speed Velocity theory, By creating a higher airspeed in the intake path you increase airmass and airspeed, which greatly increase horsepower.
This is possible by Creating two different paths of airflow, both flowing at different airspeeds, due to the tubing diameter in which the air is traveling. Now when the 2 different paths of air meet,they create a vacuum, which is where the airspeed starts to multiply, forcing more air into the engine at a higher rate, creating more horsepower.
The Secret Weapon Intake Systems are carefully CNC mendrel bent out of 6061 Aluminum, and then Hand Tig Welded in sections to ensure a constant balance in airflow, regulation in airspeed, positive seal and proper fittment. Each one of these intake systems are carefully tuned, by matching the engines displacement, air intake capacity and airspeed to the intake systems tube size,length and secondary pathway tubing diameters to maximize the full potential of the SECRET WEAPON INTAKE SYSTEM.
This Intake is Matched with our Newly designed SW1 Filter, which provides maximum airflow, with the protection of high quality dense Poly Urethane Foam. Many studies have shown Flow rates of up to 80% more Air and Better Dirt Filtration with Foam Filter than the conventional cotton filter. The SW1 main feature is an Computer CAD Designed and Flow benched Tested TURBO Velocity Stack, which greatly increases airflow ,airspeed and airmass into the engine, therefore increasing engine performance. Another one of the SW1 Filters great features are the capability to be dis-assembled to be cleaned and then re-assembled after cleanings or to change the color of the foam filtering element.
We would like to explain how the " SECRET WEAPON " Intake system works.
Here are some pictures of a flow test done with our specially designed flow bench.
Our flow bench is very similar to those used to test flow in machine shops. We measure pressure, in this case vacuum pressure, inside of the pipe. The form of measurement we use is in H2O, or inches of water. This is the same as a majority of industry flow benches. Almost all flow benches use a meter called a Manometer, which has actual water in it, to make its measurements. We opted for a more precise method, using a precision tuned digital vacuum meter, provided to us by The DigiVac Company. The easiest to read this is the higher the number on the display, the better the flow is through the pipe. All test shown were performed using a Craftsman 5hp wet/dry vacuum as a vacuum source.
Picture 1 : Picture of the PATENT PENDING " Secret Weapon Intake Pipe " design. You can see the smaller inner tube used to increase velocity. The airflow through the inner tube has a higher velocity than a standard 3" intake pipe. The higher velocity / volume of airflow from the inner pipe creates a low-pressure vacuum at the throttle body end of the pipe, called a Venturi. This Venturi draws the air from the outer pipe, increasing its velocity, and increasing the overall volume of air entering the engine.
Picture 2 :In this picture, we first test a standard 3” pipe. Here you can see that the display is reading 1.4 in H20. We cap off the other pipe to provide a more accurate reading.
Picture 3 : In this picture we are now testing the Secret Weapon design. We see that the reading has increased to 2.3 in H20. This increase is due to the small inner pipe increasing velocity in the intake tract.
Picture 4 : In this photo, we test a pretty good-sized K&N style gauze filter. You can see that with this filter, the reading has actually DECREASED down to 2.0 inH2O.
Picture 5 : Swapping a Secret Weapon filter for the gauze filter, shows a large increase over the gauge filter and over just the open pipe as well. The improved velocity stack and filter design encourages the air to flow in a direct route through the pipe while maintaining a high velocity and low restriction.
What does this all mean?
The Secret Weapon uses two important laws of physics to increase airflow. The first law is Boyles law. This law basically states that as air velocity increases, its volume increases as well, while the pressure decreases. The second law is the Bernoulli Equation, where a moving fluid (in this case air) has a lower pressure than air that is standing still, or is moving slowly. This same law is used in NASCAR for both downforce and "drafting." When we increase the air velocity in the intake, we create a low pressure area that draws a higher volume of air than a standard intake would. In layman's terms, we are creating a vacuum effect using natural laws of physics.
Do the Weapon*R Air Filters, filter dirt better than K&N / AEM / Injen Air Filters?
The Secret Weapon Air Filter is made of Polyeurethane Foam, which is rated at 300 Pores per square inch. Whereas the K&N / AEM / INJEN air filters are rated at 30-60 pores per square inch. This means that there is more dirt particles passing through the air filter to the engine when using their filters.
Why is the Secret Weapon Air Filter so much better?
The reason why the Secret Weapon Air Filter flows much better than any other filter on the market today is because of the specially designed Velocity Stack inside the air filter, it helps gather more air into the air filter and velocitize the air into the intake tube.
THis intake is teh best one Weapon R has made. Nice design, nice hp boost, and a great sounding intake. I had the Dragon before this one and i will never go back. This intake i think is one of the best out there. Improves HP by a bunch. Thanxs

Just installed this kit for my Toyota Echo.
All I can say is WOW... Better throttle response and what a sound! Nice and deep, exactly the way a car should sound. The awesome thing is, it's not bothersome... when you want to go fast and show off the noise, just hit the throttle as hard as you can.
Especially great on a little car like mine that needs a bit more of a masculine sound :)
Recommended 100%!

Installed this in my 2002 Acura RSX and wow can I tell the differance. The car pulls a lot harder and top end is increased signifcantly. Highly recomended buy if you dont want to deal with the woes of hydrolock but still want increased performance over the stock airbox.
Just purchased one for my 97 Civic DX and can definately tell a difference versus the Flea-Bay Special I did have on there. A+ Product wouldn't expect anything less from one of the industry leaders.

the intake is a good intake overall it gives good performance and the style of the intake is great we installed it on a 99 honda accord
I recently installed this intake in replacement of my Injen intake. I really noticed a huge difference between them. My eclipse had a higher acceleration and a better sound coming from under the hood. I also notice a difference in gas mileage when taking trips between Seattle and Oregon. I highly recommend the Secret Weapon intake over any other intake systems.

I installed the Weapon-R in my Z-26 Beretta 3.1L 1995.....I have to say the order came as it was stated it would. It took me approximately 90min to install. I works great,fits great,no modifications were needed. The car seems a bit faster with throttle response,pickup appears to be better also....I like the product and would definately recommend it to anyone. Thanks again for such a kewl product!

Iv had this intake installed in my car for about 2 weeks now and i absolutely love it !! it was extremely easy to install. One of the things i love the most is the nice sound it gives to my my car when i'm driving. My 94 lexus es300 used to be very quiet but with the Weapon R intake it sounds beautiful, iv gotten many compliments on how it sounds. overall its given my car a little more horsepower and i would recomend this intake to anyone, especially if you wanna give your quiet little luxury engine a nice rumble.

If you are shoppping around for a great Intake, this should be the choice you make. With no prior knowledge of installing a part suh as this this, and missing some tools from my personal tool box(from my garage not the product box), I still got this intake installed in about an hour and a half. It sounds great and you can really feel a difference in the throttle. If you buy this intake, you will not be dissapointed.

Recently Bought and tested performcance with origional intake on flowbench (Short Ram) and test came to 1.2 when compared to flowbench of secret weapon design the secret weapon pulled an impressive 3.0 @ 800 CFM. Works great with Ram Air Adaption (Custom Made).

I have finally recieved and installed the intake on my car and it made a huge difference in perfomance over my old Short Ram. The sound is also smoother when going into the high RPM's. This is by far the best intake I have ever used and I will not go back to Injen or AEM unless I absolutely have to. I highly recommend to everyone to look into this intake system even if you already have one.

The air intake is of great design. Better response time and good low to high end power. Beautiful shiny addition to your engine, if you're going for looks. The filter is really great quality product, because it is foam filter more air goes in and it traps in more dirt than paper filters. The foam filter runs real good dirty just as well as it is clean also. So you really can feel the air inter your engine.

I am extrmely skeptical about the filter on this intake . I live in south florida and i could dump sand out of my stock filter every month. about half a handful just from street driving. Yes I like the intake but its the filter im worried about. I cant have sand get in my intake, any ideas ?

Going from the stock rubber intake, air can, and paper filter to the Weapon-R Secret Weapon intake was a pretty big improvement. Slightly more horsepower and slightly better gas mileage. A pretty good buy for $177+ dollars. The clamps used to hold the rubber couplers together are actually strong enough and made well enough to withstand over tightening and removal.
However, as with all aftermarket parts, I have a complaint; the bracket meant to hold the intake up and steady is useless. It is much too flimsy to offset the added weight of the filter and intake itself. A different bracket was needed to be used since the air can itself had been removed as well.
The filter is also useless and is not the filter that is in the picture. It looks exactly like the OE filter but with foam instead of paper filter. The cleaning solution is also useless.
Also, clearance is tight between the throttle body and the battery/tray. Removing the tray if you have one should be done, but make sure you have a battery tie-down.
Overall, a good pipe, but a bad filter and mounting bracket.

I bought this intake from Pro Street over 2 months ago now and I love the deep sound it makes. Will definitely buy again from them, they are fast shippers and provide great support!

My brother bought me this intake because i wanted a increase in hp and i knew a higher flowing intake could help me get that. It took me a few hours because the intake is hard to remove on the Pontiac Vibe. It turned out great though and I love the sound
