Theyre pregaapped to .024 http://www.ngk.com/results_cross.asp...LFR7H&x=33&y=5

 

Doesn't matter what gap they start at. You got a re-gapping tool? Like $5

 

Ya, so you can repgap iridium plugs? Just be very careful, I assume.

 

$48 away from a better running car

Autozone should have them or special order. Part# 5245

 

Ya, I've checked all over town. Im just going to order them online. Kind of excited to see the difference, I hope the fact that I tuned on evo 8 plugs wont harm the new plugs when I put them in.

 

most say you shouldn't but it can be done. Besides @ .024" and your mods you're good to go

 

post up when u get them installed

 

I will, im pretty excited lol. Thanks for the help.

 

You should do a VDR for ishts and giggles. Don't touch the tune or boost. Do a pull for whp/tq with wrong plugs. Let car cool down and change plugs, then do another pull for whp/tq. Should be pretty interesting. USe the same flat road for both pulls

Just incase you don't know what VDR is. https://www.evolutionm.net/forums/ec...simulator.html It's pretty accurate.

 

autozone had these new iridium plugs by autolite. they had them stock heat range and 1 step colder for about $6.50. Just curious if anyone has tried them?

 

Ive had the same problem with plugs and gaping ive tried about everything and I have similar mods but its a evo 8? Could you help me?

 

^ what plugs are you using and what gap. you could also try swapping out your coils and wires with another evo to test it out.

 

what are your mods?

 

mbc, tbe, intake, flywheel, clutch, walbro 255, 23psi and i currently have the iriduims one step colder, im not sure on the gap my tuner gaped them like 8 times and it just kept doing it we went throught 2 sets of plugs and couldnt get it right

 

i swapped out the coils and plug wires from another evo they had at the shop which ran over 450 whp so im not sure its that
