I going to keep my 00 jdm itr stock and whated to know the types of spark plugs that you have had good experiences with. I'm looking to use NGK, but should I get the ones from the dealer that are platinum or just copper from pep boyz? If you have a part number that be great as well.

 

Go to NAPA and get some ZFR-7F11 NGK plugs. Good stuff.

 

those are just standard plugs not platinum. I heard that the standard copper plugs conduct better electicity. That part number you gave me, is that just regular plugs. they generate good power?

 

Yes. I don't run platinum plugs in my R.

 

why not platinum. How many miles have you put on your R. does it shorthen live expectincy. What car is that ngk for, because the I part # I have in my helms factory manual says ZFR5F-11 and its listed under the B18B1 motor. Why is your parts # ZFR- 7F11. Why is it different?
