CAT Cams Camshaft Set, BMW S65

Please note: All camshafts must be installed by a professional engine builder, using the provided camshaft specification sheet.

The builder is responsible for verifying piston-to-valve clearance and setting engine timing according to the cam card specifications, not the factory settings.

Upgrade your BMW S65 engine with a CAT Cams camshaft set—designed for a sporty yet practical performance boost.

Built specifically for the legendary S65 V8 that powers the BMW E90 / E92 M3, these camshafts offer modest gains over the stock setup.

CAT Cams focuses on precision engineering to deliver smoother idling, sharper throttle response, and improved power across the RPM range.

Whether you're enjoying spirited street driving or occasional track days, this camshaft set brings enhanced performance without compromising everyday drivability.
