I have an early 4 and I need to put an airfilter on because I have moved to a dusty area. I purchased the chin for the cowl and I read somewhere that someone had converted theirs and just attached the pick up to the cowl with twist locks. Does anyone know where I could get info on how to do it?

The FAB scoop can easily be attached with fasteners but on many RV4's I have inspected, cracks generate around the fittings and the scoop just looks better faired in. Most have been permanently attached although if you could figure out a good way to make it work, it would make lower cowling access a piece of cake. Most Thorp T-18's have their intake scoops attached this way and it works great. Bill Freckman used this on his RV-4 fastback and it looks great. His thread is included in the link below with photos.
