Owner reviews for spark plug

If they have a brand name plug it may be better to spend a couple $more for a NKG, Champion, Bosch etc. vs a china brand.

Find the proper ones for your engine and use NGK if possible. They’ve lasted longer in my experience when tuned.

Use only AC DELCO ignition components for GM vehicles, and that includes spark plugs. The factory plugs work perfectly.

AC Delco CR43TS.

Copper plugs are actually the best for performance, precious metals just last far longer.

FYI I had some issues and replaced spark plugs and now runs like a top.

I used NGK iridium.

NGK Laser Iridiums are the exact spark plugs as Nissan brand. just different box and a lot less $. used it on my 05 Xterra S and my 2011 Xterra S.

Highly recommend NGK. I made the same mistake a few years ago on our Odyssey with similar results. Put in NGK’s and problem solved.

2013 3.5 hitting 170k miles within a few days. Second owner so not sure how it was maintained during it\u2019s life but I\u2019ve done 10k miles so far, needed a waterpump and sparkplugs but it\u2019s pretty normal wear and tear

I replaced my sparkplugs, and everything went smoothly except for the front plug on the driver's side. All the other spark plugs screwed in with little to no need for a socket wrench - except for tightening at the end.

This one plug seems to be stuck halfway down the middle of the thread and won't go deeper unless I really torque it. When I took the new spark plug out, I noticed that the tip was bent with the spark gap being much smaller than the other new piece.

I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.
