I bought these for 2nd vert.

Can I use these for 3rd?

two of them says NGK 3559 BUR7EQ, and

two of them says NGK 3483 BUR9EQ.

Does somebody know where I can use or not...?

 

im not to sure but i dont think u can

 

On my FD plugs it says BUR9EQ but stock 2 of them should say BUR7EQ. I dont have the 1st 4 numbers you mentioned but what i do have matches with yours.

Those should be fine. The only difference between those and the "stock" FD plugs should be the lack of platinum coating (they might not last as long as stock FD plugs).

 

As long as you put the 7's and the 9's in the right places (leading and trailing) you should be good.

 

Make sure to gap them correctly. I don't know if there is a difference between what the gap should be on an NA FC and an FD, but better safe than sorry.

 

haha, its the same plug. . . the only difference is the 3rd gen is a platinum plug. same heat range and everything, just not platinum. you dont really even need platinum on these cars. . . they foul out so quickly anyways. haha.

lol good one.

 

I don't know if this is a joke or something, but you can't gap our spark plugs.

 

i just dismissed that post as i thought it was a joke. . . hopefully my assumption was correct.

9s in the top (T is for trailing) and 7s in the lower holes (L is for leading).....is your 7 stock? If not, you're definitely not doing it any favors by running 7s leading. I run 10.5s leading and 11s trailing, but it's all dependant on mods

 

My car's fairly modded and I run 7s/9s. Car idles and runs much smoother than with all 9s.

 

what mods do you have, what boost are you running, etc. I've never seen a high hp auto, so I'm curious

 

sorry...check the sig. I run 1.15 kg/cm2 boost or around 15psi give or take.

 

chuckle...PM me when you get back. You're from around Dallas right? I'm only about 2.5 hours away from there. I haven't dyno'd the car, so I guess I shouldn't make any high hp claims. Anyway, I'd love to see your car, and I was thinking of taking mine to Gotham for tuning and to discuss some oil cooler upgrade stuff.

 

Ok, cool. I should be back at Gotham by the first week in August. after looking at your mods, I'd like to check out your FD as well. White, auto, and single turbo? Never seen one of them before
