OYEAUTO3186 3951 Iridium Spark Plugs 8pcs Compatible with GMC Chevrolet Ford Cadillac Lincoln Mercury Hummer Pontiac Buick Panoz Oldsmobile Isuzu VPG Saab V8 Engine

Great products fast shipping 5 stars will recommend product and seller to all

Our poor truck is a 2001, with over 300,000 miles on it, so it needs some good plugs every so often.These went right in with no fuss, and seem to work just as well, as the name brand that we have been using before now.Since my engine burns oil, I need to take them out for cleaning about every other oil change, but they don't seem to have any issues.I am happy with them, and would use them again.

Thanks

These sparkplugs work as expected and as described. A good value.

These work great in my Chev Silverado V8. I'll update if there's a problem, but so far so good.

These plugs are cheap and made my cadillac escalade run very rough and hesitant on throttle response

The media could not be loaded.  Functionality: they work, they will spark, no perceived power loss or gain. They are in a 6.0 engine with 250k.Branding: the packaging is very generic, only a sticker to identify what these are,the smaller individual boxes aren't marked with numbers. Worst of all, the Plugs themselves have no part number on them at all. The shank says "spark plug", the ceramic says "iridium oyeauto", the next person to replace them will be scratching thier head.Compared to NGK and AC iridium plugs, these are not "double iridium" because I do not see the dot of iridium on the ground electrode, it only looks to be on the center electrode.I don't see any reason why these wouldn't work in a pinch, but I also don't see anything that would make them a better valve than the big brands. They are very generic " one size fits all" but in the same price range.

Using in my 01 6L GM truck. No misfire issues, but just installed. The threads could have been cleaned up a bit from the cutting but was able to get them installed without cross threading. The OEM plugs have been in a long time and no issues removing. Hopefully will be the same with these when the time comes.
