i have a 95 ta m6...bolt ons and a 75 dry shot (that i have not sprayed in months) and my car is backfiring like crazy...it did not do it when i had ac delco plugs and when i switched to ngk tr55 it started to get hot and backfired after a month or so...is it the plugs? do i need colder or just get ac delco again??? i have the ngk's that i am about to put in? should i? are they the right plugs? gapped at .50 thanks

 

NGK's TR6's or some AutoLite 106's not recommended to run hot plugs with nitrous

 

so i got the wrong plugs? you think thats it?

 

so i should go with the ngk tr6's or autolite 106's?

 

on a 75 shot you can run tr5's but if you step it up any switch to tr6's
start your gap at .035

 

Sounds like you might be getting some spark blowout. Check the gap -- but definitely with any forced induced application the TR6s are the way to go. Just make sure they're gapped correctly (.035)
