Cold Air Intake Pipe Diameter Options

[fgvillegas]

Hi Guys,

i am just wondering what would be the best cold air intake pipe diameter for a 3rd gen 3sge with a throttle body of 65mm (2 and 5/8").

my current setup uses 3" diameter which i think is good at the higher rpm range but i feel that i'm losing some in the bottom to mid range.

i wanted to use the same diameter as the throttle body but the only available pipe size in my location is 2.5" only.

do you think that this would be very restrictive at higher rpms?

my car is a daily driver and i use it on the track very seldom. but i run full throttle on the streets whenever possible.

thanks.

Ive tried many different setups the type of filter and design changes sound if you know the sound of your car well. for me the apexi had a better sound than the injen, fujita, and ebay inner and outer funnel type.

2nd best sound came from the weapon r filter, it was deep like the apexi. the rest are high pitched.
