The N54 spool performance HPFP overdrive kit is a high-performance part designed by Helix for fuel injection systems. This kit includes a special overdrive component to enhance the functionality of the high-pressure fuel pump, resulting in improved engine performance. Specifically designed for the N54 engine, this product is a must-have for those seeking to upgrade their fuel system for optimal performance and efficiency. What you see in the photo is what you get, I’ve put about 6k miles on it, works perfectly, just need money so reinstalling old non performance parts and selling!
