AutoliteIridium XP Automotive Replacement Spark Plugs, XP5363 (4 Pack)

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.

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

Good price, and seem to work great. Definitely a difference.

Ford may say plugs last 100 k but around 75 k my gas mileage was down to 13.5 mpg even with synthetic oil . after installing new plugs its back up to 15.9 around town an 18 to 20 highway. Also performance has improved , seat of pants feel at least cant quote any numbers . a bit of a pain to change , 5.0 coyoty but worth the time an effort. May replace in my other vehicles with model for them as soon as is required . time will tell if the upgrade holds up but am pleased with results now .

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.
