SETES B58 ignition conversion for BMW N55, All-Included Kit

B58 Ignition Coils for BMW N55 / S55 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 N55 and S55 engines are fantastic platforms for tuning, but once power levels start to rise, one of the first weak points is often the ignition system. Annoying misfires, timing pull caused by weak spark, and inconsistent power delivery are all common symptoms.

With the Finnish-made SETES B58 Coil Conversion Kit, you can upgrade to modern, high-performance B58 OEM ignition coils in a true plug & play setup. OEM+ fitment, no cutting, no soldering, no modifications required.

This all-included bolt-on kit installs in about 1–2 garage beverages, and ignition issues become a thing of the past.

Why B58 ignition coils?

• B58 coils are inherently strong and well-suited for tuned applications
• Helps prevent ignition issues such as misfires
• Provides a stronger, more consistent spark for improved performance
• Reduces timing pull and other “ghost corrections” caused by weak ignition

What’s included

• CNC-machined adapters and brackets to secure the coils firmly in place
• NGK SILZKBR8D8S spark plugs – an excellent performance plug for BMW N55 / S55 engines (NGK heat range 8)
• Dinan or BMW OEM ignition coils, depending on your selection
• Custom plug-and-play wiring harness with OEM BMW connectors
• 2 x BMW OEM Torx bolts for mounting
• Custom adapters between ignition coils and spark plugs

How is the SETES ignition kit installed?

No wires need to be cut and nothing should be soldered. This is a fully plug & play solution.

You simply choose your preferred B58 ignition coils – OEM B58 coils work perfectly, as do reinforced DINAN versions. For spark plugs, we recommend NGK SILZKBR8D8S for N55 and S55 engines (see “Related products”).

• Easy installation – swap them just like factory ignition coils
• Works with OEM and dimensionally equivalent aftermarket B58 coils
• Finish the upgrade with quality spark plugs such as NGK SILZKBR8D8S
