Autolite Iridium XP Automotive Replacement Spark Plug, XP5364 (2 Pack)

Much improved performance with the new plugs.

Used these in my 2008 Ford Taurus. Running like new after a tune up. Replaced the OEM plugs with these and instantly noticed the difference. Smoother and quicker acceleration.

Good value, but Amazon packaging was bad. I bought six of these and they were packed in a brown envelope. Most of the spark plugs had come out of their individual boxes from all the shifting. I had to carefully inspect each of them with a magnifying glass to make sure there were no chips or cracks in the ceramics.

Van muy bien

Works perfect for 08 Ford Taurus limited

These replaced my cars (08' Mazdaspeed 3) OEM plugs that were on for a good time so take this with a grain of salt;Car runs noticeably much smoother on acceleration and at high speeds. Over all just feels better, likely just the effect of having fresh new plugs on that are gaped correctly, either way great so far.Only thing to check for is the insulators on these plugs were a bit wider then the ones I had on my car and for whatever reason the spark plug socket I had even though it was a 5/8th socket couldnt fit these plugs because of the slightly larger insulators. So make sure to check your socket before you go taking everything apart like i did.

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!

Getting a misfire but no codes. Through in a set of these Auto lights and six coils and my gas mileage went up about 20%.

I ordered 4 spark plugs and 2 of them seem to be used and different from the other 2. Half of the plugs have black strips and the other half doesn't. The packaging was 4 individual boxes and all of them were already opened.
