you should check out what we offer. What mods do you have?
Hmm damn I just bought them for 55 NGK Iridiums at Oreilly
no problem, keep us in mind for the future.
K, well much needed my car runs better and smoother also added Mobil 1 synthetic motor oil
hey wasup man just wondering at how many miles did you first change your spark plugs? i only got 73000 mile on my car seem good.
you don't normally have to change them all that often
i was told i must run ngk with my new setup. i was using some new school ones i iwll try to find them.
i use ngk's in my car and they work great and are cheap. they are ngk #6779
i just bought the ngk oem replacements from crsx. put them in today. changed them at 135k for the first time. a little bit of wear on 2 of them, but otherwise they look pretty good for 135k miles.
I just got the denzo's for the rsx with my k20a3 supercharged engine. 10$ a piece. a got a great deal on them. reg price is 23$ each.
who you happen to have the denso spark plug #
NGK plugs:
NGK-IZFR6K11 = stock A3
NGK-IFR7G-11KS = stock A2 (1 step colder A3)
NGK-BKR7EIX-11 = stock A2 (1 step colder A3)
NGK-BKR7EIX = stock A2 (1 step colder A3)
NGK-BKR8EIX = 1 step colder A2 (2 steps colder A3)
NGK-BKR9EIX = 2 steps colder A2 (3 steps colder A3)
