fits Lexus (Toyota) products

I just fitted them with no problems, the mileage seems to have increased a bit even though I've only driven 200 miles and I'm guessing by on board computer rating.

Pros
  • GOLS certified
Cons
  • Not as thick as others

DO NOT BUY PART 4 ​​SALE or GPS

DO NOT BUY PART 4 SALE or GPS! Bought a used denso ik20. The box was sealed with tape prior to the apparent removal and grease is visible on the boxes and connectors. The crush washers were crushed, indicating the mounting and thread guards were missing.

Pros
  • Dope πŸ”₯
Cons
  • Something Else

Wrong landing on the car

I bought it a few months ago and just got around to trying it on. They've been confirmed to fit the Mini Cooper, but they don't. Also 2 connector boxes were open showing marks where someone had tried to install them elsewhere so obviously someone had returned them earlier.

Pros
  • A sea of positive emotions
Cons
  • Modern

What happened to CC?!

In my engineering career I have installed tons of Denso spark plugs and cursed the Denso and NGK brands. This is the first time I've seen 2 out of 4 connectors have very bad thread burrs. Had to run the crystal to clean it before installing. QC is not currently working for you? Other than that, it's usually a very reliable brand.

Pros
  • Certified
Cons
  • You could choose a newer model

The electrodes wore out on all 4 cylinders after about 30,000 miles

I bought these spark plugs from this list but the seller is no longer on the list. I was wondering why my RAV4 is not working well. Removing the spark plugs revealed all 4 electrodes were completely worn out after only 30,000 miles. I've never seen iridium connectors fall apart like that, especially from a reputable brand like Denso. So I'm wondering if I was sold a genuine Denso product or a fake. After reading the reviews, it turned out that this didn't just happen to me.

Pros
  • great product
Cons
  • some problems

NGK Eat Your Heart Out

I replaced my 50,000 mile NGK iridium plugs with these Denso iridium plugs because to be honest NGK makes poor quality spark plugs - NGK iridium plugs that only last 50,000 miles and have burned the bottom to the point where the electrodes were gone causing misfires etc. The auto parts store said Denso made a quality iridium spark plug and I might want to try it. One word describes my results - amazing - both performance and fuel economy like new and this car is 14 years old and has 195,000…

Pros
  • Constant test results
Cons
  • Not everything fits
