your wrong! so you saying that i should not install a intake then wright?
you still can gain HP if you looking for power
And what size is your intake going to be?
Most people go out and buy the biggest they can get ~ 3". But if you really pay attention to detail and actually do measurements, you would see that AEM has different sizes for the tegs.
taken from here
2.5" for the B18a/b
2.75" for the B18c1
3" for the B18c5
Of course the tegs also use differnet size throttle bodies too. However, each one take in air differently and at different rates.
And to answer your qeustion, you shouldn't really buy an intake. Stock is best. Most people just buy it for sound and cool factor. How many of those ebay intakes do you think is actually giving you any power gains?
Power potial is there, but you would have to be able to maximize the benifits for it to be worth it.
