🔌 Autolite Iridium XP XP5363-4PK Spark Plug Set, Pack of 4 Review

Great replacement spark plug for Ford 5.0 2011-14 engine. Return to normal fuel consumption and improved engine response. Be sure to set the clearance before installation. I recommend applying a light coat of anti-seize to the threads and dielectric grease to the receptacles.

Perfect replacement for my 2012 F-150 with 5.0, they seem to have changed the gap between 2011 and 2012. I made a gap at the bottom of my goggles because the electrodes wear out over time. switched off, the distance increases slightly. Now you have a much smoother idle and much smoother engine acceleration.

Definitely time to change the spark plugs in my f150. Couldn't beat the price here and even got an extra percentage off the first in-app purchase. Candles came on, rides great, changed in an hour and a half. I also bought some dielectric grease for the coil shoe and anti-seize for the threads. Rate corks as excellent

After about 70,000 miles on my Mustang GT I noticed a slight decrease in fuel economy and the need to downshift from 6th gear earlier than usual at lower speeds . Replaced factory spark plugs at 75,000. These new ones brought engine performance and fuel economy back to what I was expecting. During installation I applied a light coat of anti-seize to the threads, although the factory ones came off easily. I've also used them on an F-150 with about 80,000 miles with the same excellent results…

Perfect replacement for my 2012 F-150 from 5.0, they seem to be the gap between 2011 and 2012 years changed. They are on the low end of my specs as the gap will increase somewhat over time as the electrodes wear. Now you have a much smoother idle and much smoother engine acceleration.

Ford may say spark plugs last 100,000, but after about 75,000 my gas mileage dropped to 13.5mpg, even with synthetic oil. After installing new candles, consumption in the city is 15.9, on the highway 18-20. The performance has also improved, the fit of the pants is noticeable, at least I can't name any numbers. a little painful to change to 5.0 coyote, but worth the time. I can replace my other cars with a model for them if needed. Time will tell if the update holds up, but for now I'm happy…
