A limited edition run for the tensioner cover The K-Tuned Tensioner Cover Plate is machined from raw 6061 billet aluminum and comes ready to install with new hardware. To install it, remove the oem black cover and clean off all the sealer from the mounting surface for the last time. A razor blade followed by a green scotch brite pad and brake cleaner works well. After that, our bolt on plate can be installed and removed repeatedly with no sealer required.
