NGK Spark plug

Don't expect too much other than a little more longevity in its service life.
Actually I'd be a little skeptical in installing one unless the specifications called for one. I do know from working on late model EFI GM trucks that using anything other than the specified spark plugs causes driveability issues in short order, but maybe atv's are a bit different.

The only other thing you should do is check the gap.

Its all good... you didnt know what i meant and id rather some one stupify something then not give enough info.

Gap is 1.0 to 1.1mm, Be very carefull when checking it do not deform the iridium tip , it will most likely be at spec out of the box but good to check. I put one of these in 2 months ago and I noticed a huge diffrence in cold starts (Alot Better)And I noticed that it runs better till It warms up as well

For you folks living below the 49th parallel and have not went Metric, The required plug gap in inches is .039 to .043. I have noticed most plugs are gapped correctly right out of the box. They should be checked though.

where did you get your plug from? any certain kinda you have to get for a foreman?

auto parts store, part number 5464

did you get ur plug from a auto parts store or did you have to order it from somewheres?

I got mine from Advanced auto. Just cost a couple of bucks. The guy told me the gap was set at .040.

after i installed it today.....
it starts quicker....
idles better....
dunno if i got a better throttle response time... couldn't tell


the old spark plug was BLACK!

I got mine at O'Riellys

I bought mine at the a local Checker Auto Parts, our local NAPA parts store has them also.
The Iridium plugs run about $7. around here per copy. At www. Rocky Mountain ATV prices are simular. Worth it ? Time will tell,

I recall my stock plug was carbon black @ 215 miles when I changed it out. now I have re jetted, I hope it stays cleaner.

went and got one of the plugs that ive been hearing so much about...put it in and i noticed somewhat of a difference at idle, havent had time to go out and ride anywheres yet and see if more power or anything comes out of it but anyways thanks for notifying me of the plug

Hi
