This review is from: Autolite XP5364 Xtreme Performance Iridium Spark Plug, Pack of 1 (Misc.)
Just tuned up my Ford Focus for the first time! It's 6 years old with 90,000 plus miles on it! These Autolite sparks plug are the best! They were properly gapped right out of the box! My acceleration is super smooth and so responsive! My car feels brand new again. Plus, Autolite is Fords' OEM manufacturer of their Motorcraft spark plugs. My Focus had double platinum fine-wire plugs installed at the factory! So these Iridium with double platinum fine-wire are a slight upgrade. I also noticed a slight gain in horsepower and an improvement in gas mileage. With the $2.00 per plug rebate from Autolite, these plugs are a steal of a deal!
