New F Chassis N55 B58 Coil Conversion
Like many BMWs of the same vintage, the turbocharged N55 platform is no stranger to ignition system problems. Notorious for causing misfires, reduced power, and rough idle, the factory pencil-style ignition coil is a known weak point. In addition to its reliability issues, the factory coil pack lacks the output required for supporting performance modifications and software upgrades. While many ignition upgrades boast increased spark energy and durability, all fall short of the venerable B58 ignition coil. After years spent researching and developing the ultimate solution for N55 ignition system issues, the team of enthusiasts at Turner Motorsport is proud to offer the last ignition upgrade you'll ever need�the B58 Ignition Coil Conversion Kit.
WHY UPGRADE?
B58 ignition coils provide up to 2.3 times more spark energy than OE N55 pencil-style 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 compatible tuning software (MHD, BM3, etc.), giving you complete control over your engine�s performance.
2.3x increase in spark energy and supports over 1000 HP
