Spark plug confirmation

[RedZR]

Hello

I was hoping that I could get confirmation on the correct plugs for my 2008. A couple of years ago I upgraded the to the 2.5 pulley on the stock blower and Revised tune I replaced the stock plugs with NGK TR7ix and gapped them at 29.

In November I upgraded the blower and am now running this combination on the car with those same NGK plugs (got 620hp at the wheels)

2013/14 TVS blower
2.4 pulley
VMP Boost a pump
JLT 123 CAI
13/14 GT500 injectors
KR 500 mufflers
Lund custom tune

My questions is if these are still the proper plugs to use with this new stuff. Also, if these are the best plugs how often should they be changed- mileage wise.

Thanks for any assistance.

Still the proper plugs and gap. Mileage depends on what type of use. I'd do 10k miles on the street.

If you're on pump gas with a 2.4 upper - Brisk GR12S, 8-heat range non-projected tip plug with drivability as good as a TR6.

TR7IX user here. I had the same set on my 2011 with a stock m122, a 2.4 TVS on torco, and back to the stock m122. Ran like a champ. Even pulling them out and looking like shit, not a misfire to speak of. Solid plug.
