2001 ITR Intake Cam is the same as the CTR Intake Cam. The Exhaust Cams are both exactly the same for all the Type R cams. The Civic Type R intake cam has 3 degrees more duration and a bit more lift. Its a bit more agressive and looking at both cams the ctr cam has probably about a finger nail more thickness. ITR has 1 engraved line by distributor side and CTR intake cam has 2 engraved lines by the distributor side.
