Dominate Ignition. Upgrade to SETES®.

If you’re serious about power, tuning, and reliability—stock coils just won’t cut it. The SETES® B58 Coil Conversion Kit is engineered for those who demand more from their BMW. Whether you're chasing numbers or building a bulletproof street machine, this is the ignition upgrade that belongs under your hood.

Built for Power. Made for Perfection.

BMW’s latest-generation B58 coils deliver a spark that stock N-series coils can only dream of. We're talking cleaner combustion, sharper throttle, more horsepower—and all of it with uncompromising reliability.

This isn't just an upgrade. It’s a transformation.

Planning to run E85? Don’t Even Think About It Without This.

Consider this kit mandatory when using Ethanol. Ethanol demands more spark energy to ignite—and factory coils simply can't keep up. Weak spark means misfires, lost power, and risk you don’t want.

Premium Parts. No Excuses.

This isn’t some generic retrofit. It's a precision-engineered solution with OEM+ fit and feel. No splicing. No soldering. Just plug-and-play perfection with a premium finish to match.
