I GOT A B16A IN A CRX AND IM ON BOTTLE AND HAVE HEARD SO MANY THINGS ABOUT SPARK PLUGS AND IM NOT SURE WHICH ONES TO GO WITH??? I HEARD THAT YOU NEED TO GO WITH ONES THAT ARE 2 DEGREES COLDER, AND IF SO THEN WHAT ARE THE MODEL NUMBERS FOR THE NGK'S????? I RAN TYPE R NGK'S FOR A WHILE THAT WERE NOT COLDER AND THE MOTOR RAN GOOD BUT THEN WENT WITH A NON-TYPE R THAT WAS COLDER AND THE MOTOR DOESN'T LIKE THEM. WHAT TO DO??????
