i wasn in socal this weekend to celebrate the new year and visit my in-laws. so since im in socal i had to some shop hopping and go to autobacs,went to the the mini-meet also in socalevo.net where they had the rbmotoring evo and somebody had an evo rs.
when i went to autobacs i bought the hks drop-in and tried it right away,the evo pulled very smooth and it bumped my boost level also somewhat.i guess intakes are really better when you are ready to tune your car since having it w/o tuning sometimes causes the rpm to drop low.
