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

I have run Autolite in my Harley for over 30 years. Great plug

5 by

I put them in for a while. Switched to Accel plugs. I ordered both at the same time. Can't tell the difference between them, But either run great in my modified evolution motor. One set to run. Other for spare

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

5 by

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.

5 by

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

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

Great plugs.

Smooth running plug!

5 by

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

5 by

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

5 by

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.

great plug

5 by

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

5 by

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.

Fires right up, seem to work fine.

thought desrciption said sold as pair, found same plug locally much cheaper

4 by

A little hard to put on

5 by

Great plugs at a great price. Autolite plugs work great in Harleys.

Out performs the stock spark plug. Quick starts and cleaner burning. Well worth the extra cost.
