I have been a big Borla fan since I got my '03 350Z Brickyard..I love the sound because its not obnoxious, just throaty..which takes about 2000 miles to realize (once you install stand back cause it blows a lot of particles you don't wanna breathe, as was the case especially with my '05 Titan)....but anyway, I love the performance with a nice CAI..I know we can get one, I am partial to K&N...350Z scoop was a pain to get on but nice after (yes, I was worried about the scoop being on the low grill for water, but never a problem) and we have a "quasi intake scoop" with our altimas)..should be good to to go with a thin piece of shaped tube to the scoop..anyway i don't expect much from the intake but a nice sound. and gosh please don't put a throttle body spacer on, whistles are only good for turbos...anyway, I digress...I expect about 20-30HP avg and 10-15 ft-lbs with a nice breathing broke in system with a ECU reset..I assume with the altima its the same gas pedal mombo, we run..to reset our ecu's...anyway back to the point of the post...this may be smoke up my butt but hey, this is a new car and a new forum (for me)...so let's hope!
