Here are just a few reasons to convert to Nissan R35 ignition coils using Polar Engineering Ignition Coil Mounting Plate Kit.


  • It allows the user to run Nissan GTR R35 ignition coils on Nissan Z32 300ZX platform.
  • Upgrades major parts of the ignition system to use the latest OEM Nissan parts and technology.
  • Eliminates PTU (igniter) that is an inherently problematic part on Z32 300ZX buy replacing it with a bypass harness which is a plug and play installation.
  • Nissan R35 GTR ignition coils use 3wire connectors just like Z32 and require no additional wires unlike many other smart coils on the market
  • The only GTR R35 ignition coil kit on the market that clears factory Z32 intake manifold.
  • Nissan GTR R35 ignition coils allow running a larger sparkplug gap without spark blowout issues at high boost levels. Larger spark plug gap provides a more complete burn and smoother idle.
  • Nissan GTR R35 ignition coils have been proven way past 1800hp mark and have unmatched reliability with no documented cases of failure
  • Polar Engineering kit mounts the coil outside of cylinder head casting reducing heat soak, reducing chances of preignition that is common with inadequately cooled LS coils and prolonging trouble-free operation for years to come


Here are the contents of a kit that would be delivered in this kit:


  • New Nissan Z32 300ZX CNC Laser Cut Ignition Coil Mounting Plate Kit for GTR R35 Coils (laser cut aluminum mounting plates, powder-coated matte-black, black low profile hex head hardware). This kit is only available in that color combination. If you want a different color, the best I would be able to do is sell you bare aluminum, uncoated plates. If you want a custom color, you would be able to have them powder coated or sprayed on receipt. Bare aluminum plates would be at the same cost. If you absolutely must have a different color, please email me and I will quote you.
  • New Hitachi Nissan GTR R35 Ignition Coils (made in Japan, set of 6)
  • New application-specific Ignition Coil Boots to Fit R35 Coils on Z32 Cylinder Heads*
  • New Nissan PTU (igniter) Plug and Pay Bypass Harness (one per kit)
  • New R35 Ignition Coil Pigtail Connectors (set of 6, will need to be soldered into EFI harness)
  • Installation Manual With Detailed Instructions

*Ignition coils and boots will come assembled with all necessary modifications to internal boot springs completed and ready to be installed in mounting plates.

  • Please note that ignition dwell times will need to be adjusted in your ECU's interface to properly operate R35 igntion coils.
