Review on 🔥 NGK (96024) Iridium Spark Plug for Enhanced Performance by Kurt Ahui

Yes, this is the original product spec for WRX 2015+ and there is nothing wrong with it to save it. it's always a 5 star rating. What is wrong is how the geniuses at Revain sent them to me. First, spark plugs are actually quite fragile, the ceramic insulator breaks very easily. As soon as this happens, the spark comes out of the insulator to the head, but there is no spark. Combined with a high compression turbocharged engine, it's terrible. Buy these spark plugs for your car, DO NOT BUY THEM ON AMAZON! That is, until they get smarter and start packing them better. How do I know my insulator is cracked? I went to get my WRX tuned and was told I was misfiring due to a cracked spark plug insulator. I took a picture of the package when I received it because I was like WHO THE HELL SHIPPED THESE SPARK PLUGS. I thought (THOUGHT) the spark plugs are ok, apparently the crack in the spark plug is hard to see until the spark seeps through and blackens the crack like in my photo. However since my car was on a dyno and the spark plugs needed replacing (they replaced them all because one was suspicious and cracked) it cost me an additional $300 THANKS AMAZON! Buy spark plugs elsewhere!
