FlyingDude Posted January 17, 2023 Report Share Posted January 17, 2023 Hi guys, I’ve seen some threads about ram air removal and that ram air is actually useful in pre-J models because of the inefficiency of the air box, and that newer models don’t need it. Is there an STC to modify the air box to make it look like newer models? Without replacing the entire bottom … Potentially remove the ram air, move the air filter up, so it faces the ram air at a more perpendicular angle, and patch the hole below? I don’t have 15k for a Lopresti cowl, even if I know that it’s awesome. Thanks. Quote Link to comment Share on other sites More sharing options...
