cowl inlet air dams

Post by A2022 »

switching out from my larger red air dams to smaller blue as Spring rolls in. I find that keeping my CHTs up during the Winter months seems to make my engine happier. the one thing I notice is less spark plug residue build up and they are much cleaner, almost pristine. I use massive spark plugs.
