BMP N54 / N55 Port Injection Kit


**** Kit now includes extended studs instead of bolts!!****

Running out of fuel?  Our Port Injection Kit is the answer! 

We have developed this port injection to fit both the N54 & N55 motors that will provide you with the additional fueling needed in cars running 100% E-85, upgraded high performance turbos, or both!


Why do I need port injections can I just upgrade my current injectors like I did in my old car?


Unfortunately no, there are no upgraded injectors available on the market and even if there were the high pressure fuel pump is a weak link which also does not have a high output easy to replace version available on the market.
