Too early to tell!!
I never do any maintenance to my 1997 Honda Civic and at 22 years and more than 700,000 miles it is as reliable as when new. Since it is not my only car sometimes it sits for weeks at a time. Lately, it was bucking like a horse until the engine warmed up so I threw these plugs into it. Start to finish took about 8 minutes. Now it runs like new again. Ask me in another 10 years if the plugs are any good. So far they seem fine.

Exact fit for 2007 VW Eos
Exact fit for 2007 VW Eos. The engine was running VERY rough, hard starting and TERRIBLE gas mileage. The center electrode on 2 of the old plugs was burned down to the ceramic. The old plugs gaps ranged up to/above 0.050 (+1.27mm) !! Like the fact that these came pre-gapped to .040. Also, replaced all 4 coils at the same time. Car now runs smooth and easy starting!

Popped right in my Dodge Caliber 2011.
Ordered this to repair my 2011 Dodge Caliber, the car was stuttering while driving for quite some time. I had initially assumed it was a transmission issue as the dealer where I get the cars oil changes for free said there was a transmission leak. After some research I found that the usual cause for the stuttering is old spark plugs. I ordered this and a spark plug socket for my ratchet and had the job done in less than ten minutes. Very simple repair, the plugs are easily accessible and the spark plug socket with the magnet meant I didn't have to fish around for the old plugs. The Caliber is now driving much better, absolutely no stuttering. Will update review if product fails abnormally quickly.

"Watch out for COUNTERFEITS!"
But these seem genuine after a close-up professional inspection; from top to bottom & a cup of coffee 😉 Exactly what I need for my 2001 Toyota 4Runner & its' waste-spark ignition so no need for the dual-grounds, anyways... "NGK & Denso #1☝️, remember that!"

This fits my 2002 Toyota Corolla and it works as it should. If anything happens I will update. For now it's great and thanks for fast shipping!!
