Greetings, I did the first test fit of my cooling ducts, and there's hope for them. I still haven't decided exactly what I'm going to do to seal the front of the duct to the cowl inlet. There's only about 1/8" gap at most, and I'm thinking that it will probably work fine without any additional seal, however, I'll probably try to put some sort of foam strip to get some sort of a seal. I looked through all the pics I have, and can't find a picture that shows the front of anyone's duct. How are you guys sealing these to the cowls? Pictures???
