Apart from that, NGK is my go-to brand for everything they make.
NGK iridium for plugs.
I set the new ngk's i put in to 0.27 and I feel a difference already lot less hesitation off the bottom end felt like it would almost hiccup before gaining any power with the stock plugs. now i lay into it and it just goes fairly smoothly
Just installed NGK 92274 in a 2021 Mazda 3. They are 'Ruthenium' instead of iridium, seems to be their newest plug available. Just don't touch the gap, it was perfect at .044. Runs great.
Have used NGK on every vehicle I've ever owned. They've often lasted the life of the vehicle.
ive put about 15k on a stock gapped set, no issues APR IS20 87 tuned,
You will be fine if you go with them. Like others have said it's a solid plug and no issues so far with mine.
I run them. They are a good plug.
Try changing out the rs7 plugs and go to NGK R7437-9 or 8. I’ve heard the RS7 plugs having issues in these cars.
Don't think the platinums give much of a performance advantage and they foul faster if you've got any oil burning going on...
