BMW F-chassis M5, M6, M550, & M650 Charge Pipe Injection (CPI) Kit for the S63TU & N63TU Motors

Fuel-It! S63TU/N63TU (CPI) Charge Pipe Injection Kit

Running ethanol blends and finding your HPFP's can't keep up?  Here's the solution to your problem.  Our CPI system runs off your low pressure supply and helps to supplement the fuel system so your HPFP's can keep up.  These kits are only recommended for use with an E30-E50 mix and for those that are running upgraded intercoolers with meth bungs post intercooler.

If you need a flex fuel kit to monitor your ethanol content, those can be found here...
