Oil is the life blood of your engine. Ensure its purity with a cost effective solution. Enter the Mishimoto drain plug, made of 6061 aluminum with a neodymium magnet to capture metal debris. The strong magnet will collect particles your oil filter might miss and prevent them from circulating in your FA20DIT where they could damage bearings and numerous other critical components. Each Mishimoto drain plug comes with an oil seal and washer to prevent leaks.
