Fit our 2008 Ford Focus!!
The fit was exact, performance of the plugs seem to be as good or better than OEM. They work great. They were easy to install, no bad threads and they were properly gapped. Would buy again!

Coolest plugs for my Grand Marquis
Gapped at .045 they’re the coolest plugs I can get for my grand Marquis. I have full bolt ons and require a cool plug for my setup. They’re good for about 10-15k miles but that’s fine. Takes roughly 60 mins to replace and reduce spark plug substantially. Very pleased with these plugs. Anti-seize not needed too which is great.
