BMW Engine Parts

If you're noticing misfires, poor fuel economy, reduced engine performance, or ignition-related diagnostic trouble codes (DTCs), a failing ignition coil is likely the cause. Late-model BMWs, such as the E60 M5, E63 M6, and E64 M6, use a coil-on-plug ignition system, where each cylinder has its own coil and spark plug for efficient ignition. When a coil fails, the affected cylinder won't receive a spark and will misfire. Even if the misfire doesn’t trigger a DTC, you’ll still feel the difference in engine performance—rough idling, hesitation during acceleration, or a strong fuel smell. To avoid these issues, we recommend replacing your ignition coils every 40,000-60,000 miles.

The S85 engine uses a specialized ignition system called Ionic Current Control, which differs from traditional knock sensors. BMW engineers developed this system to more accurately detect pre-ignition and misfires in the high-revving, ten-cylinder S85. Instead of relying on conventional knock sensors, the system uses each spark plug to measure current after the power stroke, transmitting that data to the Ionic Current Control Unit (ICC). This allows for precise monitoring of combustion events. To support this, the S85’s ignition coils are specially designed with a modified “pencil” shape and lack a Zener diode in the secondary winding, allowing for accurate current measurements without triggering fault codes in the engine control unit (DME). These ignition coils are manufactured to the exact specifications of the OE Ionic Current Control-compatible ignition coil, and will not trigger ignition-related fault codes in the DME.

Bavarian Autosport ignition coils are engineered for reliability, delivering a consistent, long-lasting spark. These high-quality OE replacement coils are specifically designed for your S85-powered E60 M5, E63 M6, or E64 M6. Constructed with durable, heat-resistant plastic and featuring premium rubber spark plug boots, each boot is pre-lubricated with dielectric grease to ensure smooth installation and prevent corrosion.

Whether you're fixing misfires, replacing a faulty coil, or performing preventative maintenance on your S85 ignition system, trust Bavarian Autosport ignition coils for a dependable, lasting repair.

Vargas Stage 1 N55 turbo upgrade is good up to 425whp with proper tuning and high grade fuel. Vargas N55 turbo is an all-new turbo specially made for Vargas. They build it with a billet compressor wheel of their own design and a stock turbine. It will accept all of the stock water and oil lines and the original diverter valve (upgraded DV is recommended). This kit is a direct bolt-on replacement for the original turbo and necessary if you want to start making big power from the N55.

The stock plastic diverter valve and chargepipe is the weakest point for boost leaks (the plastic cracks). Vargas Turbo recommends upgrading it to a stronger DV design. The aluminum DV designs will hold up to just about any boost level currently available.

Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. For the BMW market, they identified a need for both cost-effective turbo replacements and proven turbo upgrades. It's recommended that the rest of the system be upgraded to handle your tuning goals. The final Vargas rebuilt turbos are better than the factory rebuilds and at a lower cost!

Oil Recommendation - modern engine oil is formulated for emissions and to be environmentally friendly. The additives in current oil lowers the oil's ability to withstand high temperatures and stresses, lowering its shear strength and its lubricating properties. Vargas recommends oils with high ZDDP (zinc and phosphorus) content that will better protect and cool the turbo bearings. Examples of high-zinc oils are Red Line Race, Red Line Euro, Motul 300V Racing, Joe Gibbs Racing, Valvoline VR-1 oil, and most Diesel-spec oils that you can buy off-the-shelf. Some oils, especially the Race type, will need more frequent oil changes and may be harmful to catalytic converters.

WHP rating: 425. This rating is used to compare various stage of Vargas turbo kits. There is no advertised horsepower gain with this kit as it depends on your other mods and tuning. The rating is provided as a reference to use in your tuning planning. Custom tuning is recommended to match thIS turbo to your existing mods and upgrades.
