Iridium and platinum, excellent performance and durability, as good or better than equivalents of other brands. Great value, plus fast delivery by Amazon.

I never really cared for Autolite plugs until now. I was using OEM Bosch plugs in my BMW R1100RS motorcycle and was experiencing idle and acceleration issues. The plugs tested good, but a recent article I read recommended these plugs. Problem immediately was resolved when I swapped over.

Cannot comment on their longevity, as I just bought them for my Honda NC-700X motorcycle. The OEM (I think) was NGK something or other, which cost $18 to $30 EACH!! These are also iridium and cost about $5 each. Bike started right up and runs great.

OK guys no yelling - I bought these 2 1/2 years ago as "have on hand replacements". They are still in my "Spares" box in the car -- fuel tilter, air filter, trans filter, frt brake pads +++. I bought them to replace the set I installed like 14 years ago in my 2002 Subaru Forester. Still running the same plugs all these years-- 185k on it. Don't do as much driving since I retired - couple thousand miles a year now. I feel guilty every now and then when I think how long they have been in that engine. Autolites don't surprise me though - the set in my 69 stang (bought June 1969) I put in in 1971 and they still get the job done when I occasionally fire it up.

If you're still buying iridium spark plugs at the auto parts store I don't know why? So much cheaper and just as good stop going to the auto parts store

Fake spark plugs! No protector sleeves. Different electrodes. These will damage your engine if you install them!

使用に支障はないでしょうが、国産品だと先端保護の筒があって安心ですね。あと、この見た目で判断してください('ω`)
