New Blox Racing K Series 70mm Throttle Body

Upgrading your VTEC throttle body is a must for any Honda enthusiast. For K-Series owners and swap enthusiasts out there who are having a hard time deciding which throttle body to go with, BLOX has the answer for you. Their all-new K Series 70mm throttle body solves multiple problems that have long plagued K20 owners.

If you own an aftermarket K20 intake manifold, chances are you know exactly what this challenge is. Buying a K series throttle body without also purchasing an intake manifold adapter has been nearly impossible.

Owners with a PRB/PRC or RBC/RRC intake manifold will either need an expensive throttle body adapter or replace the throttle body altogether. Good news is, BLOX Racing has you covered with this multi-purpose K Series 70mm throttle body.
