They're spark plugs. Nothing magical but function fine. Get platinum plus for copper price.

I have a battered salvage title 2001 F-150 with a 4.2 v6. The plugs were toast. The 4.2 tends to be picky about plugs but the reviews on these were good so I gave them a shot and boy am I glad I did. I've driven several thousand miles now and no issues at all.

One of my spark plugs came dented, easy fix so no big issue

Fit perfectly, quality is great

I figured I'd save some money and ordered these alongside a set of wires from the same company to do a tuneup on a 98 F150 that had 1 misfire code but still started and ran fine. Save yourself the headache and money, because both were unusable. I couldn't get the wires to seat on the plugs to save my life, and they literally fell apart in trying to get them to click. I went to a local store, got their cheap wires, and was able to get them seated in all of 5 minutes. From there I still couldn't get it to start, so I took out one of these and checked the gap. The gap on these measures 44 and the spec is 54(I checked the old plugs to verify what I read online- they measure 55)

After setting gaps to .054 they were ready to install. Excellent value.

As described, work great.

Exactly we expected.
