Autolite Iridium XP Automotive Replacement Spark Plugs, XP5363 (4 Pack)

These replace the factory sparkplugs and work as well or better.

Great price way better than same plug at parts house

My car just rolled past 200,000 miles so I wanted to replace the spark plugs before they failed. They came pre-gapped (which I checked) and they are a great value for the money. These also have the fit, quality, and performance I'm looking for.

Great fit came in clutch at the right time !!!

Good price . For a quality spark plug

Perfect fit. No issues at all.

Amazon said that the factory gap is .050 in. It is actually .040 in. Otherwise the plugs work well, and I am getting 4mpg more than I was on the factory plugs. 2012 fusion.

A great spark plug with a lower price than auto parts

Todo bien aunque aconsejan a cuanto deben ir calibradas es mejor basarse en el manual de propietario ya que en mi fiesta iban más cerradas por el tipo de motor pero el producto es muy bueno

I had 2 issues, throttle position sensor was giving erroneous readings and car was Surging and very rough idle. Spark plugs were changed and that cleared up the rough idle as well as cleaned up the fuel trims, see before and after pics as well as Before video. Throttle body was changed and then the surging stopped (I had a continuous poor throttle position sensor and the car would frequently go into limp mode with a wrench symbol on dash, I was able to temporarily fix issue with OBDii code reader and tapping pedal a few times during startup), I found my throttle body for $90 on Amazon! Car is 200% better and no more Surging or Fuel Trim issues, see before video of crazy fuel trim values and pic After of good fuel trims. Sorry pics/video isn't better quality. Thanks Amazon & Enjoy, my fellow Amazonian Peeps!

Quedan bien en mi f150 5.0 y funciona sin fallas

Proper fit for my 2012 Ford Escape . check your gaps all my plugs were gapped differently all had to be opened up for gap spec for my vehicle

Producto al 100, servicio excelente
