Which spark plugs should I use for my 97 civic turbo project? Going to be pushing 12-20psi, around 300whp. Thanks!!

 

HKS makes some good stuff.

 

NGK BCPR7 i believe they are........make sure u get a step or 2 colder thou.

 

For that application i would go withe the bosch platinum 4's 2 steps colder, they worked well for my EF hatch, single zc on 15psi.....

 

These NGK BCPR7, do they sell them at Autozone or do you have to order them. How do you know if you should get a step or two colder? Whats the differene? From what I heard you can just retard the timing and should be ok, but thats on lower boost.

 

i've got Bosch Platinum +4's and have no complaints...

 

only plugs that have lasted for me is ngk bcpr7's(ones i use for turbo/nitrous apps) burned up bosch, zex, denso........i dont like the bosch platnum types or the zex because its harder to read the plugs.

 

platnum arent good for f/i. Andrey, the colder plugs are the same, you just ask for a colder version. Yea, they sell em @ auto part stores. THey mite have to order em, but theyre the same price.

 

Bad news Pete. I dont think you gave me the correct number for the plugs. I've ran around town to three auto stores including autozone and advanced, and they dont have those plugs. They cant find the number. However, one said they have NGK V-power, and those are a step colder, that I can special order. Put the part number doesnt even come close to BCPR7.

 

do a search on ebay, i bought some from there a few weeks ago.
