Schrick 264/248 Camshaft Set - E46 325i/330i, E39 525i/530i, Z3 2.5/3.0 (M54)

Camshaft tuning is all about optimizing air/fuel flow for your specific needs. These sport cams for the M54 engine in the E46 325i/330i, E39 525i/530i, and Z3 2.5i/3.0i will have more power in the mid and high RPM range with stable idle and no loss of torque in the bottom end. The intake cam has 10.5mm of lift and the exhaust has 10.0mm. Both have more duration so the valves open deeper and longer to expedite flow. These cams are more aggressive than the ZHP cams that are a popular upgrade but don't have as much gains as the Schrick (especially at high RPM). No additional hardware is required although new spring retainers and keepers will be a good idea on high mileage engines. There are many other "while you're in there" parts to do as well so contact us if you have any questions.

Manufacturer's Notes:
1. While new springs may not be required, you must ensure the new valve lift does not fully compress the spring. It may be necessary to shim the spring's installed height.
2. Valve timing and valve opening durations are shown minus the ramps.
3. Valve timing is shown in °Crankshaft in relation to TDC.
4. All valve lift figures are shown without deduction of valve lash, i.e. the actual valve lift is the stated valve lift minus the valve lash. Hydraulic lifters have no lash so the valve lift is the actual valve lift.
