A-Premium Iridium Platinum Spark Plugs Compatible with Ford Explorer, Escape, Fusion, Focus, Mustang, Taurus & Lincoln MKZ, MKC, MKT - Turbocharged

So, I'm a professional automotive technician. I've seen a lot of cheap Amazon parts come through my bay, usually after a botched home install, or after the oxygen sensors lasted a week as they're known to do. In this case, I'd actually used the A-Premium brand brake calipers before when a customer supplied them to me, and I was blown away by the quality, $100 for two brake calipers that had really good corrosion protection, quality castings, and didn't immediately start to leak? My attention was seized by this brand. Recently, I had someone who was pretty much actually dirt poor come into my shop with a turbo Ford. Misfiring intermittently, when I pulled the plugs, they looked very, very sad. The copper plugs at the auto store were actually unaffordable to this person, but I wanted to help, but I also didn't want to toss copper plugs in a high compression turbo engine that was going to shred them in short order. So, after some thought, and reading some bad reviews of these, I sprung for them to at least try, especially after the good quality of the brake components from the same brand. Well, when I got them, they all had a different gap, none were anywhere near OE spec. This is bad as you have to make SURE that when gapping, you must NOT come in contact with the tip of the ground electrode, AND the center tip of the positive electrode. This is where I believe a lot of bad reviews come from, if you gap these incorrectly, you will ruin them instantly. These are double fine wire, meaning they have a small fine wire on the ground electrode, and a small fine wire on the positive electrode. This is GOOD for performance, especially at this pricepoint, considering these are iridium plugs. So, after carefully gapping them and installing... they've been great so far. I put these in at the beginning of Septemer 2024, and it's now about to be November 2024. The vehicle returned for a routine service and no misfire codes, no BS. I pulled one of the plugs and it looked... like a nearly new Iridium plug. I wouldn't have known it was a cheap plug other than the brand. They held torque and don't seem to be half bad for the money, once again proving to me that this brand may actually have some serious value engineering behind it, and not just your run of the mill rebranded garbage. Overall, once gapped, these are great. Note: A bunch of reviews mentioned these did NOT have protection around the threads of the plug, like those cardboard/plastic sleeves used to ensure the plug can't drop/rest on the electrodes. In the ones I received, they DID have protective sleeves around the critical parts of the spark plug, meaning I didn't get ANY with a fully closed gap, the gaps were just very random, and completely adjustable.

The price was affordable and the spark plugs worked to perfection.

I installed these a while back and so far they're working perfectly. Seem to be good quality!

Excelente

2015 Ford Edge has 89000 miles. Replaced the plugs with these and vehicle appears to run smoother and have a better idle.

Good

My mechanic wanted to charge me 450 for a tune up so I did it myself Worked great

got these and install 9/2024, here we are in April 2025 and their bad. Previously I had the factory originals from 2017, only replaced to help with a diagnosis of something else. (the most returned item warning was NOT on the page when I ordered)

Quedaron y funcionan sin falla

My car had knocking issue which has completely been resolved with these spark plugs.

they wore good for the price

Al pareces todo bien hasta el momento, las compré para mi mkz 2013 2.0 y ya no hubo necesidad de calibrarlas, venían ala medida si sale algo mal en estos días cambio la reseña o agrego otra más

Fonctionne parfaitement ! À voir dans la durée
