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.
