Good bang for your buck
Ordered this for my S40 T5 and it has awake it a little. My butt dyno has noticed a bit of improvement in the HP and torque. BUT the sound this intake gives you is really where its at! No need for a new blow off valve with this, you really hear the turbo spool and the release of pressure with this intake. Worth the money for sure!\ Also, this part says only fits a C30, not true, this is the same part as S40s and I believe V50s.

Taking apart the old unit was fairly difficult because the airbox became wedged between the radiator fan and the cylinder heads. After that when installing the new unit the fit was not quite right and the mounting bolts do not actually fit into the mounting positions. But, this is probably just an issue on my vehicle. Overall the unit sounds great, works well and I am happy to be finished with the install.
