Happy New Year, need to change my spark plugs on my 07 sport sedan as I am at 108k now. On rock auto they always reference 2 different motors, which one do I have and what exact plug do I need to order?
Engine Code VQ35DE or Engine Code VQ35HR?

I am thinking the HR code is my car since 07, but not sure, and I think I should use Denso iridium plugs or ngk but again a lot of choices on rock auto so hoping for exact part numbers please, thanks!

 

2007-2008 sedans are HR. Lift your hood. If you have dual intakes, you have an HR. Stick with Nissan OE plugs and if you have the time and money, get the Z1 high spark coil packs.

 

Thank you, I figured it, but again thank you very much for responding!
