    Okay after searching and reading up on NGK sprak plugs for the past hour and a half i have come to the point of slight confusion :huh: . My setup is a d15b7(stock) with a TD04L turbo at 7-8 psi. Now i wanna go either 1 or 2 steps colder....i have got the P/N ZFR6F-11(its stock gap but will regap to ~.33 or so) thats for one step colder. Now if i wanna go 2 steps colder i need to get a BKR7E? I guess after going through the P/N chart i am confused, will the BKR7E work fine on my car(thread and depth wise), are the BKR and ZFR interchangable :huh:?

    Oh yea i am looking at the v-power line of plugs.

    Thanks for any help! :worthy:

    The spark plugs you have will be fine. Those are the same plugs I run.

    thanks, ya i read that all and still am a little confused....i understand the graph its just that, is it okay to use a "BKR" plug? Cuz it seems that's what everyone says they use.

    ZFR6J-11 plugs are what you want to use.

    I don't have any problems with my spark plugs. My car runs pretty rich at part throttle and WOT too according to my plx wideband o2 sensor.
