Bosch FGR7DQP spark plug for multiple BMW engines. Listed as BMW part #'s 12120037607, 12120141871, and 12121435955. Over time spark plugs become contaminated, worn, and "fouled out". This can cause a weak or missing spark leading to issues with fuel efficiency, misfires, check engine codes, and poor idle or even direct damage to your catalytic converter. This OEM spark plug made by Bosch will restore OE spark plug operation and function, returning lost power and fuel efficiency.

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! The included brackets, cover plates, wiring harness adapters, and proprietary boots make for an easy installation Confirmed functionality with factory M3.3.1 (OBDI) and MS41 (OBDII) DME software PART DESIGN:
