It fits great, you wouldn't believe how many people can't tell it's a 96" twin-cam unless it says so on the filter:lolrolling the gasket just sticks to the inside of the cover to hold it out a little further from the engine. I tried it first with out the gasket and the cover hit the engine before it sealed to the filter. I suppose another option would be to get a taller air filter but the gasket was 5 buck and easy to put on. I don't know the part number but I could find out.
