SETES B58 ignition conversion for BMW N54, All-Included Kit

B58 Ignition Coils for BMW N54 3.0L Inline-6 – Overhaul Bundle!

SETES coil conversion kit, smartly priced as a complete combo – fix your ignition in one go and save some cash. Includes NGK spark plugs and your choice of BMW OEM or DINAN ignition coils.

The BMW N54 is a fantastic tuning platform, but once you start turning things up, one of the first common issues is annoying misfires. Weak spark can also lead to ignition timing corrections (timing pull), which quickly kills power and consistency.

With the Finnish-made SETES B58 Coil Conversion Kit, you can upgrade to modern, high-performance B58 OEM ignition coils using a true plug & play solution. No soldering, no cutting, no modifications – just clean OEM+ fitment.

This all-inclusive bolt-on kit can be installed in about the time it takes to enjoy 1–2 cold garage beverages – and your ignition issues are history.

How is the SETES ignition kit installed?
