Review on E3.42 Automotive Spark Plug by E3 Spark Plugs - Single Pack by Charles You

DO NOT BUY THESE CHEAP SPARK PLUGS IF YOU CAN'T MAKE IT TWICE, MAKE IT RIGHT AND MAKE IT THE FIRST TIME. These spark plugs immediately rejected all my engine power, loss of power, I have an automatic engine, SHIFT 1st to 2nd was too long, 2nd to 3rd was too fast, and 3rd to 4th I have almost half my Lost engine power, I just had the engine rebuilt by a Chevrolet dealer for $1800 under warranty and they did a dyno test to show me the cause of the engine power loss. I bought Ngk spark plugs and now I'm on the Autobahn!
