Looking to upgrade your ignition coils? We at Clean Injection Performance have been designed this kit to replace the the OEM RB26 coils to the high powered Nissan R35 GTR ignition coils. The factory RB26 Coils simply cannot create enough energy to jump the gap in high cylinder pressure/boost applications. Nissan GTR coils have become the most demanded coil in the performance scene as many are producing over 1400whp with the factory R35 Coils. This kit includes Clean Injection Custom made plug and play Coil Harness. Designed using high temp TXL wire which meets SAW J-1560 requirements. TXL wires are protected using High Temp Nylon braided sleeves allowing the harness to handle engine bay temperatures ranging from -59.8°F to 280°F. The TXL wires and sleeves are secured using heat shrink tubing lined with adhesive.
