The intake setups that work best with off-the-shelf Cobb maps are:
1. Cobb short ram intake (with or without heat shield box, preferably with)
2. SPT short ram intake (with or without heat shield box, preferably with)
3. stock intake with K&N (or other brand) drop-in replacement panel air filter (with or without snorkus delete mod)
If you still have the stock intake, it would probably be best to reinstall that and sell your typhoon for a few bucks if you plan on running a generic Cobb map for a while. If, however, you plan on getting more parts and/or a pro-tune via the AccessPORT in the near future, you can probably keep the intake you have.
