This kit is capable of providing supplemental fueling to all MK5 Supra's and also BMW's equipped with B58 Gen 2 engine (see fitment guide for full details).

If you have a B58D, this will work. If any other version, then please select the Precision Raceworks BMW B58 F22 G01 G05 G20 G30 Gen 1 Port Injection Kit (M240i, M340i, 440i & X5 40ix).

The complete kit integrates seamlessly into your car like it left from the factory with it installed; you can’t even see the kit once the car is assembled! This kit includes everything needed to add multi-port injection and is 100% e85 compliant. We include new genuine Bosch Motorsport injectors which are flow matched both static and dynamic by an outside lab to industry leading requirements. A Detailed certificate of conformance and genuine Bosch product certificate is included with each kit giving you all flow data needed for optimal tuning.

Don’t be tricked into thinking all port injection kits are equal, the Precision Raceworks is the only port injection kit currently where all 6 injectors have even fuel distribution for each cylinder. Additionally this kit features 750cc* injectors standard (this flow rate is based on industry injector flow test pressure of 43.5psi) at 72psi these injectors flow 1000cc. What this means is our kit is capable of supporting builds from 400whp up to 1,000whp out of the box.

Simply pick up this kit and pair it with your favorite injector controller and you are ready to go! Our favorite injector controller is the AIC-6 which is compatible with all B58 cars and is the industry standard which is why we offer it with this kit.
