Heres the deal.
I got a 97 ex coupe with a D16Y8 SOHC & Greddy kit (15g) tuned at 10psi
I was told by the owner who had the car set up to go 2 degrees colder on the plugs and to us NGK V-Power plugs gapped at .030 (Thats what it was tuned with).

So here's the deal. The plugs I pulled out were NGK-ZFR6F-11 gapped at .020-.022 range and appear to have normal clean burn on them. The plugs the autoparts store looked up for me that were 2 degrees colder were NGK-ZFR6A-11 (A) being the only difference.

Either way I bought them and gapped them to .030 and the car started fine and it boosted just as it was before the plug change.

Simple questions.. Do I have the right plugs? What should I be looking for as far as how the car runs?

Notice how I said "owner who had the car set up". I bought the car from the person he sold it to but actually found the original owner through a message board, so that's how I came up with the proper set up spec's. Oh I also have the MSD Cap with external MSD Blaster 2 Coil set up.

I just need to know if the plugs I just installed are fine or will they cause any damage to my set up? Most everything I searched says to use a #7 range although the plugs I put in reference to be 2 degrees colder but only show #6 in the discription? *Confused*

Thanks for your time

i beleive stock sohcs run heat range 5. at least my d16y7 does. 6 is one step colder.

run a 6.

 

Thanks nickromeo
I'll keep an eye on them and see how the car does.

Research on many forums shows to use the NGK BKR7E-11's

I'll have to PM the original owner and see if he remembers what exact plug the car was tuned with.

Thanks again.
