The 09 TSX intake high speed lobe has less lift and duration than the 06-08 TSX (but only a little) It is better than the 04-05 TSX camshaft though.
The 09 TSX intake low speed lobe has more lift but less duration than the 06-08 TSX intake camshaft.
Our opinion is that the 06-08 TSX intake camshaft is the best choice for top end power.
