Genuine Honda Cam Timing Chain Tensioner R-Series R18

Genuine Honda OEM cam chain tensioner. Over time the chains can stretch causing the ECU to throw a light and the tensioners become loose. The tensioners often need to be replaced on engines that are nearing 100,000 miles or on engines that have spent their life bouncing off the rev limiter. Maintain your engine just as Honda intended.
