Ok im trying to find the best plugs for our cars...Im running ac delco single platninum gapped to .026. I run e47 on around 25+lbs of boost on a 5557 im wondering what everyone recommends for plugs for our cars on higher boost and E. Thanks alot

 

I'd say get the E3 spark plugs cuz they get like triple spark duh!!!!

 

NGK-iltr6a-8g stock#3787

 

Agree on stock. I think every kind under the sun has been tried. Stockers are the best.

 

where do you buy the stock ones from...like orielys and advance

 

i got mine from rockauto.

stock is best. i have a bnr2871 with stock plugs at stock gap and my car is fine. ive run as high as 28 psi.

 

i cant find them on rock auto i suck hahah

 

ngk's are better with E

 

Where can i find them when i go to rock auto i dont see 3787 and i can only find them on amazon

 

I bought mine a A-Line.

 

maybe im just terrible looking for them...might just have to buy the ones from MPX

 

^^^summit racing has the ngk 3787's

good idea Bryce i second that notion....

 

i run the stock ones i get from my work at a gm dealership and my car actually runs best with them at 15 psi...cheap as can be too

 

Step Colder NGKs work well also, especially on a really aggressive tune. LTR6IX-11 is the model number.

 

That's almost as good as having VTAC, YO!!!!

 

Uh...tell Tyler to order them in at his work?

ngk iridiums.... 1 step colder is what i ran with that setup.

 

^^^^ NGK 3787's.

 

WHile I ran those for a while, those are really hard to gap down properly from the .045 they ship as.

NGK 3787's are the same as the stock plugs, (5476) only 1 step colder.
