Rennline Heater Channel Billet Block Off Plates

If you've removed the heat in your 911/912/930, chances are youÂ’ve left the heater channel opening in your frame rail wide open. Over time water finds its way into these holes and the end result is corrosion in your rocker panels. These billet aluminum block off plates come as a pair and include hardware as well as gaskets to ensure a watertight seal.
