This version uses aFe's highest flowing filter media, which uses a lightly oiled gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.
This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:
E30 3 series: 318i, 318is 318i Convertible 1990-1991
E30 3 series: 325e, 325es 1986-1988
E30 3 series: 325i, 325is 325ic, 325ix 1987-1991
E28 5 Series: 528e 1986-1988
E34 5 Series: 525i 1989-1990
E32 7 Series: 750il 1988-1994 (requires 2 of these filters).
Since 1999, aFe (Advanced FLOW Engineering) has been developing and manufacturing high quality accessories in their facility in Corona, California. Starting with air filters and intake systems, and now expanding into exhaust systems, suspension components, tuning modules, and more, aFe products are a great way to improve the performance of your BMW without altering its fundamental character. Owned by a BMW enthusiast, aFe power is recognized the world over as a leader in quality performance products for your BMW.
This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.
By the early 1990s, BMW had phased out its canister-style ignition coil in favor of an individual coil-on-plug system. The venerable M50 was one of the first engines to receive this update, which boasts greater overall efficiency through increased ignition control and spark energy. Unfortunately, over two decades later, the ignition coils used on the M50, M52, S50, and S52 engines are antiquated at best. Our team of engineers and BMW enthusiasts realized the need for an ignition system upgrade and set out to modernize the M5X ignition system with performance ignition coils pulled from the B58 parts bin.
WHY UPGRADE?
B58 ignition coils provide up to 2.5 times more spark energy than OE M5X ignition coils, effectively eliminating misfires even on high-performance setups. Whether your vehicle is heavily modified or completely stock, these ignition coils deliver unparalleled performance with zero downsides! For tuners, the Turner Motorsport kit also allows for precise adjustments to ignition dwell time through standalone engine management, giving you complete control over your engine’s performance.
Our kit utilizes the factory mounting locations and includes a proprietary boot design with a built-in 1k OHM resistor. Unlike many aftermarket options, our design prevents electrical contact springs from burning out, ensuring long-term reliability and durability. The included ignition coil bracket and cover plate are manufactured from durable 5052 aluminum, combining rugged durability with a premium aesthetic. Designed and optimized in-house using cutting-edge 3D scanning hardware and CAD software, our kit ensures a perfect fit and a clean, factory-like appearance. Installation is a breeze with the included adapter harness, allowing you to add modern ignition coils to your M5X with ease!
Eliminate misfires and unleash the full potential of your M5X-equipped BMW with our industry-leading B58 ignition coil upgrade. Designed for easy installation and unparalleled reliability, it’s the ultimate plug-and-play solution for performance enthusiasts.
FEATURES:
B58 ignition coils offer upwards of 2.5x more spark energy than the OE M5X ignition coils Eliminates common ignition system defects - no more chasing misfires or swapping around coil packs!
