Im looking to replace the sparks on my heavily modified aw11. It has much higher boost pressure, longer duration cams, larger fuel injectors, etc.

The ones on there right now have performed well enough, but theyre getting old(er).

Ive read good things about the Bosch platnium +4s, but im not sure, maybe ill just get the iridums again. Anyone here have any advice, the price doesnt really matter (theyre spark plugs.....)

Whatever i get, i cannot afford a misfire, i really dont want damage to the engine at this stage in the game.

Also, whats the thread size for AW11 mr2 spark plugs (wow im embarrased i dont know that but the last owner didnt have a owners manual.....)

i would get copper cores.... they will give the best spark... however, they will not last like platinum or iridium

well if the ones you have perform pretty good already, why not use the same, just new? Why take a chance?

well if anyone here has any experience with plugs on their modified aw11s, id really like their input

I use bosch platinum. The engine requires them to be platinum.
