Review on 🔧 Enhance Engine Performance with Fel-Pro ES 72481 Spark Plug Tube Seal Set by Steven Darkshnar

Good quality product. Fits with modifications on my Maxima valve cover. I had to use a 2" hole saw on a power drill like in the Astral YouTube video and drill a hole around the old rubber piece. 1-3/4 was undersized and hit the aluminum plate built into the valve cover. So I chose 2 inches and got the best result. Sanded and cleaned the brake in this area after removing dirt from the plastic. Then I applied gray RTV Right and pressed in new tubes. Perfect fit, no leaks and I couldn't be happier at the moment
