Howdy new to site and have lots of questions. I have a 2000 F-250 extra cab long box 4x4 six speed stick ts chip four inch turbo back exhaust. My turbo pumped while pulling trailers so I bought and installed ported turbo housing. By the way great product and I highly recommend installing one if pulling a trailer. Anyway my question is does anyone make a four inch O.D. stainless intake tube that will work with the new turbo boot. Oh yeah I did the CCV delete so I need the intake tube to be long enough to accomidate that modification. Or should I just buy the 6637 filter and use the factory intake tube. I have extra 4" O.D. stainless pipe so no worries there. Alright that's it for now thanks for any help.
