Description
Cat Cams Camshaft 305°/306° – BMW 6cyl 2.0L 12V SOHC (M20 B20) is a performance camshaft profile from Cat Cams, developed for the BMW 6cyl 2.0L 12V SOHC engine. Cat Cams has built valvetrain components in Belgium for decades, and every profile is ground to motorsport tolerances rather than adapted from a generic blank.
Key Features:
- 305°/306° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
- 12.20mm intake / 12.20mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
- Chilled cast iron construction: chilled cast iron construction, the OE-style material, holding its profile under sustained high-rpm loading.
- Correct valvetrain match: ground specifically for the rocker-arm SOHC 12v configuration, so it drops into the standard head.
- Made to order: ground to spec by Cat Cams in Belgium, so the profile arrives fresh rather than off a shelf.
Fitment:
- BMW 6cyl 2.0L 12V SOHC – engine code M20 B20
- M20
- rocker-arm SOHC 12v valvetrain
Camshaft changes of this size normally want matched valve springs and a revised tune to realise the profile fully — talk to us if you want the supporting parts specified alongside it.
