Hello I have a 7th gen Maxima with a 8th gen swap, I’m running a few mods,headers , 3” full isr exhaust, custom y pipe, single exit, 3.5” intake, uprev tuned, few other things.

anyways my question is, I was looking for the best possible performance purchase for my spark plugs, I seen HKS and some other ones on z1, however those are for older generation VQs it would seem.

I have 2021 vq35 so I’m wondering which spark plugs I should buy? As well as some ignition coils?

I wanted to go one step colder. Right?

I need the pros to advice me please, thanks.


Ps: I was under the impression that it should fit all VQ35DE but was told negative on that assumption
