I bought these a few months ago, but just installed yesterday. I did use a little anti-seize, but everywhere I read that it's not necessary. The one thing I had to search for is the torque spec since I would rather rely on that than some fraction of a turn. The best I could find out was that I needed to be in the 20-30 N-m range. I set it at 25 and they seated nicely. The rear 3 were extremely difficult to access, but that's the car design, not the plug problem. I do feel like the car is refreshed and has a bit more power than the ones that had 110k miles on them. This should be the last set I will ever replace on this vehicle before getting rid of.Quality of the plugs seemed very solid and the price was perfect. I can't speak to mileage or longevity yet. Seems worth the money.

After 3 years of not doing a tune up on my car I finally decided to buy these spark plugs! After installation immediately felt my car running smooth! The spark plugs are pre gapped and easy to install!-Diesel Duke Jr.

worked great

5 out of 6 plugs are great, one of the plugs had a bur on the thread and could not be used.

Good item

Excellent seller I recommend, great product I arrived on time.
