Better gas mileage.

By   on  Verified Purchaser

These plugs increased my gas mileage on my Harley-Davidson M8 114 cammed. My guess about 10-15 per tank full of gas.


Now this is the good stuff

By   on  Verified Purchaser

Really good deal on spark plugs for my Harley Davidson, replaced the stock spark plugs easily.

By   on  Verified Purchaser

Parts were as described. Will definitely do business with you again.


Thanks!

By   on  Verified Purchaser

They really helped the performance of my motorcycle!


I highly recommend

By   on 

Got a pair for my 02 1200 Bobber that's not stock by any means and I noticed a big difference. Heck of a plug. I highly recommend them.


Great product

By   on  Verified Purchaser

I have an 02 sportster 883 xl custom and replaced the stock plugs and they seem to make a slight improvement on throttle response and I'm happy with the product and would recommend.


Plug tips

By   on  Verified Purchaser

Very good plugs, one of the tips broke off while I was Gaping it. Used it anyway. Runs good. Tiny tip could be an issue. Plugs too expensive to break

Questions & Answers

Ask Question

do these fit my 103CI 2015 street glide special

Yes, if you were to choose the  2015 Harley Davidson FLHXS Street Glide Special iridium spark plugs from our fit guide, you'd receive the correct components to fit your machine. They screw right in place of the OEM plugs.
