I used OE hoses without issue, actually had to cut them to fit.
Check out your intake temps. pre and post Typhoon intake and then take into account the ECU begins pulling timing (power) when said temps. get to 85-95*. You will see WAY higher than that with Typhoons.
I'm still using the Typhoon tubes but "built" my own CAI from the ends into the bumper cover.
