GUMMETAL GRAY [Transistor cover] A cover that closes the dent on the back of the plug cover from which the genuine transistor has been removed. RED Carve out a 3D shape Lightweight lightening processDraining shape that prevents water from getting caught from the top Black nickel plated bolt Features A cover that closes the dent on the back of the plug cover from which the genuine transistor has been removed. It is finished in a shape that smoothly connects to the curved surface of the plug cover. Manufactured by carving out aluminum material, it gives off a beautiful metallic shine with an alumite finish. Alumite is available in a gunmetal color that is easy to match with any color and a red color for BNR34. The back side is lightened to the utmost to reduce weight (98g). I attached a drainer to hang down at the rear end without entraining the water flowing from the top surface. Uses bolts with beautiful black nickel plating that does not rust easily. If you want to match the color with the surroundings, we recommend painting. Note) There are some individual differences in alumite color, and heat may cause fading. * When using SUPER FIRE RACING COIL PRO 43005-AN001 ~ 3, it is necessary to process the plug cover.
