This can be done during any belt or pulley service or anytime the fan is off the engine.

If your valve cover is leaking oil or a bad seal is causing vacuum issues and check engine lights, we recommend replacing your seals with this complete valve cover gasket kit! This kit includes all of the main gaskets and o-ring seals used by BMW to seal your valve cover to the cylinder head. Included: Victor Reinz Left & Right Valve Cover Gaskets Genuine BMW Oil Separator Seal O-rings - Two Per Valve Cover Genuine BMW Crankshaft Position Sensor O-Rings - Two Per Valve Cover URO Spark Plug Tubes w/ Gaskets If you are not replacing your valve cover, we also recommend inspecting the grommets found on the valve cover bolts. Over time these can compress or split, leading to insufficient sealing of the valve cover to the cylinder head due to a lack of pressure. BMW does not offer these grommets separately from their individual valve cover bolts, but NRW Design came in clutch with their Silicone Valve Cover Grommet Kit.

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application.

The Turner Motorsport S65 Ignition Service Kit restores ignition timing and ionic knock-sensing accuracy on the BMW E9X M3 S65 engine. Worn spark plugs alter cylinder electrical resistance, disrupting ionic current knock detection across the ignition coils. Replacing all eight NGK plugs, S65 coils, and applying AGS dielectric boot protector restores precise combustion and knock monitoring.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes ECS Kevlar Reinforced Drive Belts, tensioner assemblies, and new tensioner pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!
