Our Coil Pack Upgrade Kit allows for your engine to use N series coil packs. This upgrade will provide over double the energy output of the original coil packs while also providing improved fuel economy. This upgrade is a must for high Horsepower engines or turbo/supercharged engines as the N series coils will provide a more consistent and stronger spark. Our kit has been designed to run with the factory wiring harness and factory ECU on the factory tune, making this upgrade plug-and-play (in order to take advantage of the more powerful coil packs a re-tune is recommended but not necessary). The kit includes 8 wiring harnesses and 8 coil pack brackets, Our wiring harnesses have been designed to outlast race-grade harnesses as they are water resistant, dust resistant, and heat resistant.

For installation simply insert the N series coil pack through the coil pack bracket ensuring the rubber boot is bottomed out on the coil pack bracket's lip after that simply push it down into the sparkplug hole ensuring that you hear a click sound (if you do not hear a click sound this means that the coil pack or the coil pack bracket is not aligned properly and is not making contact with the sparkplug, if that happens simply reinstall it). Once everything is securely bolted down simply plug in the wiring harness and you are ready to go as shown in the photos.

These coil adapters are a true upgrade. They are very well made and a welcome addition my BMW e39 M5. I utilized Dinan N series coil packs with them.
