I recently installed R35 GTR Spark Plugs on my 2002 Nissan Maxima which has a 2014 Maxima engine swap. I went this route for my custom Supercharger setup. These plugs are 1-step colder are a direct fit. I paid $91.58 on eBay for all 6 shipped. I replaced them at the same time I did the Audi R8 coil packs. The gap on the spark plugs is .031″ (0.8mm).

Update 5/29/2020: These are still working great for me with no issues. 

Note: These only work for the Gen2 VQ35DE Swaps. You will also need a 9/16″ Spark Plug Swivel Socket to install these.
