Brisk Premium LGS Racing EOR15LGS Spark Plug

Been a buyer of Brisk plugs for years. Use them on my truck, wife’s car, and all our 4 wheelers. Have never had to change a plug since. You’re not going to get a noticeable gain in HP, but you are going to notice a little better throttle response, a slight increase in gas mileage, and most importantly; a move efficient burn and cleaner combustion chamber with less carbon build up on your vehicles valves, which will increase the longevity of you vehicles engine. Hands down, the best plug I’ve ever used.
