Default Spark Plug Recommendation for NA-T

I have a 97 SC300 5speed and I am currently getting ready for my NA-T modifications. I just got my car serviced today to ensure that everything is in proper working order for when the boostlogic stage one NA-T kit goes on next month. Here's my problem. I had the spark plugs changed as a part of my maintenance, but now I am having second thoughts as to whther I should have had them replaced with something other than the oem spark plugs. Please help me out if you have knowledge on this subject. Would it be a problem to run the oem spark plugs with a NA-T setup such as the boostlogic Stage One? If so, why and what would be better? What would you do in my situation? Sorry for all the questions, but I need to figure this out before next month when the turbo kit goes on. Thanks in advance.

Mike

Stage 1 sounds to me like you're retaining stock sc300 headgasket. If that is the case, I recommend NGK 3330 spark plugs gapped at 0.032. Stock plugs are gapped at 0.0444 i believe. You can also go dith some denso iridiums.

my personal choice is hks or blitz iridiums. i had ngk and i don't see a great difference, but a difference none the less. i am assume iridium overall is a great buy. i had hks and now i am running the blitz. its a pretty penny, but like i said its my choice to buy iridiums in general. i only went name brand because the shop i take my car to hooks it up for a price i can't say no to.

Thanks for the recommendations. Do you guys think that if I leave the stock spark plugs and wires I'll run into any problems or am I just not geting the most out of my turbo setup? Let me know what you think. Thanks again.

The stock plugs are a little hot and the gap is too big. That's why the above recommendations are a good idea to follow. If you run those plugs you may get some det and you'll surely blow out the spark with that gap at upper boost levels.

The rest of the ignition system is fine for NA-T so long as the components are within spec.
