Description
Cat Cams Camshaft Set 257°/257° – BMW 6cyl 2.5L 24V DOHC (M52 B25) is a performance camshaft profile from Cat Cams, developed for the BMW 6cyl 2.5L 24V DOHC 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:
- 257°/257° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
- 10.15mm intake / 10.15mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
- Billet steel construction: machined from solid billet steel for maximum strength, holding its profile under sustained high-rpm loading.
- Correct valvetrain match: ground specifically for the M-engine with hydraulic lash adjustment DOHC 24v configuration, so it drops into the standard head.
- Supplied as a matched set: ships as a complete set of 2, timed to work together rather than mixed with a stock shaft.
- Made to order: ground to spec by Cat Cams in Belgium, so the profile arrives fresh rather than off a shelf.
Fitment:
- BMW 6cyl 2.5L 24V DOHC – engine code M52 B25
- M52 (VANOS intake)
- M-engine with hydraulic lash adjustment DOHC 24v 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.
