Spark plug Denso or AC DELCO

I recently was having a misfire in cylinders 2/3, and new plugs and ignition coils cleared it up.

DENSO ZXE24HLR7 is also an excellent OE plug.

Denso 3289 is what I run.

398k on the clock, like 50k on these plugs, she runs clean and smooth.

Denso for my runner

Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that

Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.

OEM are actually cheaper than a lot of aftermarket plugs. Buy from a place like bell Lexus or just get the denso branded equivalent. They last hundreds of thousands of miles in some cases, so OE has certainly proved its worth

They look good but if the vehicle has 83k, they were replaced before, Denso is OE on toyota and Autolite are shit plugs so no way they were in since the car was brand new.

definitely not ok, they are spent, also Denso>NgK any day of the week

I bought eight new AC/Delco from eBay. While gapping the plugs, I noticed that in two of them, the ceramic was not concentric with the body of the plug. It's difficult to measure, but it's easy to see by eye. I'd estimate the error is about 0.02 to 0.03 inches.
