this is for the u.s. evo, not jdm evo. took about an hour to install. cel came on. just had to disconnect the battery to reset the ecu and no more cel light. as for the test drive: OMG. it pulls a lil harder and is it's more responsive. the sound is just overwhelming. u can really hear the turbo spool faster and the bov sounds like an aftermarket. it's really intimidating. i highly recommend it to anyone looking for a good intake.

 

you installed the MAS upside down?

Took me about an hour as well, no CEL, serious pull high end.
