Autolite Xtreme Sport Iridium Automotive Replacement Spark Plugs, XS4303 (4 Pack)

Their top plugs

these plugs are iridium enhanced. not sure what that means, but at this price, and expectations based on previous autolite spark plug experience i think i will get good service from them.

I ordered for my honda shadow. Had an issue with the first set of plugs . Amazon made it right I received a whole new box of plugs they looked great . Unfortunately I went to change them and the plugs were too small in diameter. Well i give up so I'll hold on to them for possibly future project.

Autolite plugs to replace NGK in a Japanese motorcycle??? My bike wasn't running right with one cylinder missing out. I cleaned the old NGK plugs that only had 5500 miles on them to no avail. I was a little apprehensive using these plugs instead of a known motorcycle plug, but these fit, and now the motor is running like a top. Of course I won't know for quite some time, but if these Iridium plugs last as long as they're supposed to, these should be a major improvement over the stock NGK plugs.

Problem with the confusion of how many plugs were to be shipped was resolved, hopefully it won't happen to others.

It's just what my 2006 Artic Cat 500 needed to get it running again!

Quietly fix the problem with misfire, works good but the problem with cold start is not resolved, for the money I pay for them they close not the best ones, but works great. If not the price may give them 5 stars.

These plugs worked well in my 2006 Kia Spectra 5. Never use Bosch plugs in this model... they burn up SO far, so good with the Autolites
