⚡ Denso (4712) IXEH22TT Iridium TT Spark Plug - Enhanced Performance, Long-lasting (Pack of 1) Review

upon receipt, I carefully checked each candle according to the points that I could find on the Internet: a thin central electrode, there is no copper saw cut at the end of the side electrode, the drink looks like a factory one, the o-ring cannot be removed and has the right color, the ceramics look to be of high quality, nothing is unscrewed and does not falls off. While running 500 km, it works clearly.

I put it on the vesta with the H4M engine, instead of the copper NGK LZKAR7D-9D (94951). In terms of dimensions and other indicators - one to one. The only analogue of iridium candles that I could find. I hope they go at least 100,000 km. I took it in March 2023 through emex at 1400 apiece.

They worked great, I was going to buy NGK for $4 more but settled on these. I feel like my access to the car is better than before! Would buy them again.

Original quality and replacement for my 2014 Accord. Driven for a couple of weeks and the engine runs smoother with no hesitation from the stop sign as before.

These are quality spark plugs for the price. Although I had a problem with landing. They were shown to be compatible with my 2007 Infiniti G35 Coupe 6MT, but upon installation I noticed the thread diameter was much smaller than the OEM in the car. This and the size of the nest has reduced to 14mm. Unfortunately it doesn't fit my car.
