I used these to help with a problem my bike has of backfiring once in awhile after the ignition is tuned off. they worked very well and last about twice as long as the original plug

  Posted:

Best plugs I have run. evo or tc!

  Posted:

Great plug and price.

  Posted:

so far working well !

  Posted:

Great plugs, but make sure you gap them for the ignition you are running.

  Posted:

nice plugs. exact fit! ! !

  Posted:

Great Value

  Posted:

Nice plugs.

  Posted:

Work great hard to believe spark plugs can add pep to a stock bike.

  Posted:

Great spark plugs

  Posted:

very good spark plugs!

  Posted:

Great plugs for the money. Easy start ups on my carb bike. use these on all my bikes

  Posted:

Excellent Plugs!!! Noticed my New Bike (only 2000 miles) runs better after swapping to these. I've put these plugs in other bikes with the same excellent results.

  Posted:

no problems as of yet, no fitment issues came well packaged and in good condition.

  Posted:

Still testing on my 883 Iron. So far so good.

  Posted:

Got many miles out of them, no miss very happy!

  Posted:

Reliable performance on a mildly modified Twin Cam

  Posted:

Excellant plugs. Run nothing but Autolite and these are the best.

  Posted:

Great plugs.

  Posted:

Smooth running plug!

  Posted:

If you are doing your own work it will pay to use these plugs.

  Posted:

Nice plugs, I expect to see a bit better throttle response.

  Posted:

Every time I buy new plugs, I buy the latest, greatest plugs on the market. Then a couple months later, I throw them away and buy another set of these. You think I'd learn, but I'm a sucker for a great ad.

  Posted:

great plug

  Posted:

Excellent spark plug, smooth idle, excellent performance. Picked with the help of JP Cycles chat line.

  Posted:

Sweet. Slight but noticeable difference. Smoother ride and less popping. It's hard to tell without a dyno run, but the bike feels more tiny bit more powerful. They look really well made, let's see how long they will last. Up to now, they seem like a good bang for the bucks.

  Posted:

running a 93 hot setup in a 67 flh these are the only plugs i use. they idle better than any other and are excellent on top end. greate for carb motors
