Performance Gains

Infinity claims 10 to 12hp from 6,000 RPM to redline. I will test the intake on the dyno with the S65-EVO.

V8 Breathwork.

The S65 intake design was arguably the most well optimized intake BMW M has ever created for a naturally aspirated engine.

Creating something objectively better was a technical challenge many promised they'd overcome, and few delivered.

In this Special Series, I look back at BMW M's sealed intake history and take a deep dive into the technical features of this unique sealed intake by InfinityDesign.

I briefly cover installation notes and record video clips of the increased induction noise. Most importantly, we will put this design to the test on the dyno with the S65-EVO.

Enjoy,
- Matt
