Post car model year mods and plug you need can be posted.Ahh ok. Im just trying to find some that will do better than the denso I put in there. I've seen the ruthenium ngks but wasn't sure about them either
Just a heat range 7 plug like oem 14 and 15 VT hasI’ve been running ngk SILZKR7E8EG
So a 17 VT. Manual or DCT? Mileage? Get it new or used? What do you mean turbo flutter? Video? What plugs are in it now vs what were in there before? Plug gaps?Door sticker says 16 but its late date so a 17. Just have a cold air intake and magnaflow muffler done. No tune. Been getting that turbo flutter in the lower to big range rpms under heavy load and im guessing its the plugs getting blown out.
If I'm not mistaken- Hyundai realized that the heat range 7 was way too hot, & that's why all models after like 2016 I think, went to 8 heat range. I'm running NGK 1422'S (heat range 8) and they're pretty good. No complaints. $40.ok new to the forum and I have search the spark plug threads but im wondering if the Ngk silzkr7b11 would work in a 16+ VT. They are 7 heat range and same specs as oem.
