bought a custom air cleaner for my dodge V6. but it didnt have a spot for the PVC intake. as i keep trying to get something to work the plastic fitting broke. so i end up with a 1/2 " hose with a broke fitting in it. most of the parts are old and hard to work with. the broke fitting looked like the same size as the air filter for a stock Traxxas 3.3. so it DOES fit. i think some permatex #2 will hold it in place.
