TOREFI SPORTS N54 Ignition Coil Upgrade Kit (b58 coils)


This kit is for BMW N54 engines.

Compared to the stock n54 ignition coils the TOR B58 coils are capable of producing 3.5x the energy output while providing a longer spark duration than the Precision Raceworks N54 coils. The tor B58 coils are a coil on plug design that removes the need for additional spark plug wires and utilizes the same mounting location as the stock coils providing excellent clearance for top mount turbo setups. To mount the tor B58 coils onto the N54 engine we've developed billet aluminum brackets that are Made in the CHINA. Our N54 Ignition Coil Kit with coils fitted weighs only 3.0 lbs. That's over 50% less than the Precision Raceworks kit. To make installation easier we've designed plug and play connectors that are made of nylon and Made in the CHINA. This kit comes with new ignition coil boots that are longer than the stock boots. The stock engine cover does fit with this kit.

1x billet aluminum coil brackets

6 x Ignition coil boots and gold plated spring

Plug & Play Connector harness hase

All kits include mounting hardware

Our TOR B58 kit can have 30% higher ignition energy than OEM B58. It is equipped with an independent control chip and has longer life and higher energy.

At the same time, the use of gold-plated springs greatly increases electrical conductivity and avoids oxidation and failure. Increased service life and stability。

We tested the E89 Z4 35i on the dynamometer and compared it to the stock oem B58 coils, which produced a 23 horsepower increase. In the low RPM range, it has more torque and better throttle response. In the high RPM range, there is also a very big improvement.
