Just wondering what everyone's experience has been with different plugs here. Anyone gotten better mileage, performance, from changing to something else?

 

I've gone to 7ES's due to horsepower and the ignition misfiring, also gapping helps. What do you drive, what hp, what do you have now, etc etc...

 

I have an 06 RS... i'm just wondering if there's anything out there better than the stock plugs for gas. I'm hurtin' over here lol.

 

im goin with the 8es

 

Stock iridium plug at .020 to .026, I don't think it will effect mileage at all.

 

i just put my plugs in i gaped it to .022! should i change my gap at all i'm running 22psi

 

I have been searching for the answer to my question but I have not found one in particular plug that I would like because I am also in the need of spark plugs for my stock 03 Evo. My car just mis fired on a long trip for me, and I have been told this has happen once before. Any recommendations for any particular brand? Also what would wires would you guys recommend as well?

Thanks a million

 

the plugs came pre gaped to .020! should i gap them bigger then .022 does it make a diffrence?

 

replace them with stock part plugs/wires
