I jsut ordered a cold-air kit from mark heuffman (buickgn.com) and i have read here, and on their site, that to run it you need to replace the stock fill tube with a regular type breather cap. I know I could just block off the hose going into the intake and keep the stock one, but mine is all crapped up and falling apart, and I'd rather get a new one. Does anyone know where I can order one? I'm sure there are a couple different places that sell em that will wokr for our hotair cars. Thanks for any info
