🔥 Enhance Performance with Denso (5353) IXUH22 Iridium Power Spark Plug - Pack of 1 Review

Like other buyers, I received one plug in one order and two in another. Bought in October but didn't have time to install until the first week of November. Around Thanksgiving, the Smart machine started working very hard. I threw away the code indicating a misfire in the 3rd cylinder. He took out the candles and number 3 was black and all sealed. Moved this candle to the second cylinder and it still works poorly. The code indicates a misfire in cylinder 2. I dug up one of the old candles from…
