Ive been running eBay denso plugs for 4 plug changes. You need to read reviews and look at the packaging to make sure they're not counterfeit. They've lasted me and performed exactly as they should.

Pros: lasted and performed
Vehicle: Toyota

I have a 2012 Civic LX (purchased new) and replaced the original spark plugs at 100k miles with **Denso 3483 (DXU22HCR-D11S)**—which were listed as compatible on RockAuto at the time. I’ve had great results and am now at 200k miles, looking to replace them with the same.

Pros: great results
Vehicle: Honda Civic
Mileage: 100000 km
Part number: 3483 (DXU22HCR-D11S)

There is a noticeable improvement in performance when I cross over into the next country and refuel. This is what my denso iridium plugs look like after 20k km. I had a misfire. New plugs today, and the misfire is gone

Pros: noticeable performance improvement
Cons: misfire, poor fuel
Mileage: 20000 km

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.

Pros: look good
Cons: shit plugs
Vehicle: Toyota
Mileage: 133575 km

The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.

Cons: disgusting appearance, tips gone, wide gap, slight miss
Vehicle: Kia
Part number: IKH24
