Review on Bosch FGR8DQP Platinum Spark Plug by Jerome Turner

I love these spark plugs, have been using them since the product came out about 8 years ago (give or take). Bosch Platinum 4 spark plugs are gapless so you don't have to mess around with gaps. The four pins provide a spark every time (no misfires) and allow you to place the spark directly on the tip of the candle for better combustion, which also increases candle life with less carbon buildup. I've been using them for 6 years and have never had a misfire. In fact, the only reason I decided to change them after 6 years was because of a leaking valve cover gasket leaking around the spark plugs. All in all a great product well worth the extra money with a quality name you can trust - Bosch!
