Just curious to know why you need iridium plugs given the higher octane gas that is available in Japan? NGK Platinum plugs should be more than enough.

 

the gas out in town is better but the gas on base is alot cheaper i mean alot cheeper too right now gas out in town is 215-220 yen per leter thats roughly $6.50- $7.00 a gallon and thats not even the high test stuff. i am going with the NGK's everyone swears buy them so i figure they would be worth a shot and i can cut costs in four thanks guys.
