Cat Cams Camshaft 301°/301° – BMW 4cyl 1.8L 8V SOHC (M10 B18)

Description

Cat Cams Camshaft 301°/301° – BMW 4cyl 1.8L 8V SOHC (M10 B18) is a performance camshaft profile from Cat Cams, developed for the BMW 4cyl 1.8L 8V 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:

• 301°/301° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
• 11.25mm intake / 11.25mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
• Correct valvetrain match: ground specifically for the rocker-arm SOHC 8v 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 4cyl 1.8L 8V SOHC – engine code M10 B18
• rocker-arm SOHC 8v 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.
