2018 F150 Coyote. Runs great.
Bought these to get iridium plugs back in my truck the factory changed to Platinum spec plugs for service intervals and they have a much shorter service life. Did them at 85K miles because I drive pretty hard and I found the factory recommended changing plugs at 65K if you tow a lot. I figured heavy right foot probably simulates some towing and the gap was out of spec already. Anyways, truck runs awesome, definitely idles and accelerates a smoother in traffic. Installed at the factory set .043” from NGK. Lots of people online freak out about it not being a .055” gap for the coyote. They run great. If anything they will burn to a .055” gap after a couple years of driving. But with these efficiently and performance results, I am very happy with these plugs in my 2018 F150 5.0 V8 Coyote

Great Plugs
These were perfect for my 2016 F-150. Gapped easily and fit great. Would highly recommend these NGK plugs.

Perfect Replacement for MX-5
Replaced the 19 year-old spark plugs in my Mazda MX-5. Experienced an intermittent check engine light and occasional acceleration hiccup, after install installation of these and new coils no more check engine light and smooth acceleration, even when the engine is cold.

Great deal, decent performance, easy install!
These spark plugs were a great deal and they were a perfect replacement for my 2014 Ford Focus. I opted to change them out early at 44K miles to maximize MPG and performance. They came pre-gapped from the factory with the utmost of precision. The threads felt strong and firm while installing. In the past, some cheap plugs' threads have felt soft that tend to give when installing. Not these. Easy peasy installation. While unscientific, I picked up about 4 MPG (~10%) since replacing them. Since I installed them, I have had no issues and have even noticed a slightly smoother idle.

Running Great
I've been using them for close to a month now on my 2012 Mustang GT and everything works great.My old spark plugs needed a replacement so these really came in handy with a pretty low price

Great spark plugs for our Mazda Miata
Excellent spark plugs that were properly pre-gapped for our Mazda Miata. Nice to have that "spark" back in the engine. LOL!
