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

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.
