🔌 Pack of 4 Autolite AP5263 Platinum Spark Plugs - High-Performance Engine Spark Plugs Review

Of course we replace spark plugs for spark plugs that have traveled over 100,000 miles. Much easier to start and I expect a better run, time will tell

My 2015 GMC TERRAIN 2.4L ecotec was diagnosed with a misfire in my #1 cylinder. Coil and all spark plugs changed. Works problem-free so far. These forks are of great value. I will continue to switch my spark plugs to Autolite.

Disappointed! My spark plugs arrived and I noticed that some of the cardboard valves were cracked. When I took the forks out of the boxes, I noticed that they were already in use. Looks like some poor guy put his old candles back in the boxes and gave them to Revane.

Came with a clearance of 23 but it was necessary to have 27 40. After the correction I drove normally for several months. Random misfire days began, new spark plugs solved the problem. The gap looks good as does the rest of the fork. Either I have a bad fork or my 2007 Chevy Cobalt 2.4L is not compatible with this product. I should have spent a little more and started with my usual brand of candles.

This is a great price compared to the platinum spark plug prices of the competition. Installation was easy, just like installing a spark plug. Remove plastic, remove coil packs, or plug in wires. Remove spark plugs, apply anti-seize to threads, install spark plugs 1/4 turn, apply dielectric grease to boots, install everything else. I'd say it takes about 20 minutes on GMC terrain.
