Autolite Iradium Spark Plug XP3923
You can bet this is a superior product! I works excellent in my 1997 Acura Integra Type R. I recently got 36.7 mpg with this plug on a car that has almost 200,000 miles. Emissions are great. I really like these plugs.

Name brand with great history
Autolite plugs have always worked well with my vehicles since 1970. Have not worn out any iridiums yet, so can only say they do last a long time.Verified purchase: YesCondition: New

Start of a test
I bought my 2011 car new; 94000 miles later I thought my GM vehicle would have AC Delco plugs, Wrong-NGKs. A video showed these plugs and they are priced right, so in they went and wamo, just like new. Time will tell if they last nearly as long as the originals, but I sure hope they and the car will survive the test of time.Verified purchase: YesCondition: New
