What spark plugs for a mild build GSR?
I have a gsr block with USDM ITR pistons that gives me 10.8-11.1 compression. Cams, IHE, tuned on crome to 192 whp. What kind of spark plug should I use? I've been using the Denso Iridium spark plugs for just the regular GSR and its time to replace them so I've been looking to buy the same ones again online am not sure if should go one step colder or not.
Do I need to run one step colder? Also, should I get them for the GSR or for the ITR since my block and cams are similar to the ITR? Should I look into NGK or anything else? And where is a cheap place to get them online? thanks in advance guys.

go do a full pull and shut down at peak rpm. coast the car to a stop and pull the plugs
look at the groundstrap and only go 1 step colder if you need to.
i believe gsr's are heatgrade 6, you can probably use a 7, but only your engine knows
