More efficient high-pressure fuel system for Audi 4.2 FSI V8 engines.
BAR-TEK® upgrade high-pressure fuel pumps are designed to significantly improve fuel delivery to the Audi 4.2 FSI V8 engine. The upgraded pumps are based on the original OEM pumps that have been modified to provide higher fuel pressure and greater flow .
Upgrade pumps deliver up to 50% more fuel than a standard pump , making them an excellent solution for tuned engines and turbo and supercharged conversions .
