Why Choose Cowl Saver?
Your Ultimate Baffle Seal Material Choice
So why choose Cowl Saver material? Baffle seals are known to cause airframe vibration and destroying your cowl – simply from the friction of materials. Typical silicone rubber baffle seals have a coefficient of friction among the highest of any known material. This friction transfers engine vibration into your cowl and firewall, causing fastener fretting, fatigue, cracking, chaffing, and airframe vibration. Cowl Saver has 30x less friction than tradition silicone seals. We use Bi-Flex™ Technology, which offers flexibility to only the necessary areas. One side of Cowl Saver is silicone, while the other side is low friction Teflon coated rubber, which is unique to our baffle seal design. This material difference reduces vibration transfer to the engine cowl and airframe – eliminating cowl erosion and drastically reducing vibrations. You can actually feel the difference. We are so certain of this, that we guarantee your satisfaction with our 36-month money-back guarantee on Cowl Saver.

What is Bi-Flex™ Technology? This exclusive McFarlane technique utilizes a laser engraved waffle pattern to provide the ideal flexible seal for maximum cooling, while retaining rigidity on the lower half of the seal to prevent the baffle seal from blowing past the proper seal position against the cowl.
