Kotte Upgrade – Exhaust camshaft -M5 F90 S63

This specially optimized exhaust camshaft improves the fuel supply to the high-pressure pump (HPFP) and ensures a consistently high delivery rate – even at high engine speeds and powerful engine configurations. Pressure drops in the fuel system at high RPM are effectively reduced.

The revised exhaust camshaft also enables operation with full E85 fuel. Ideal for performance-oriented applications with increased fuel requirements.

Important notes:

* Suitable for S63TU4 models
* Our camshafts and the BMW F90 high-pressure pumps (HPFP) are also required for S63TU vehicles
* Replacement base (Core Exhaust Cams) required
* Only the exhaust camshaft is modified
