I've had two air filters distort. The air filter medium is bent out of shape. The air filter cover plate that should hold the air filter in place cracked where the leading edge on the outboard side is bent up to screw in place to the baffling. I don't have my plans with me, as I am away from home for the next 3 months. Anyone know the part number for the air filter hold down cover plate? IO390 engine, standard Vans finishing kit baffling. Anyone else having a problem with their air filter getting distorted? Any suggestions about what to do? Thanks, JDW
