Can anyone running an H22 tell me what model of NGK plugs they use (non-platinums)? Honda gave me some RFH6F-11's, and Carquest assures me that RFH6A-11's are correct. Now, I know you're all going to say, trust Honda on this one. The problem is, the one that end in 'A' fit my plug wires MUCH nicer. I get that 'pop' when I insert the wire. The ones that Honda gave me (the ones that end in 'F') don't fit my wires nicely, which makes me think that's the reason I friend my plug in cylinder #1. I've emailed NGK as well, just thought I'd get the low-down from my Hondaswizzap homiez.
