I have a couple spectre short ram intake tubes (3" diameter) that I am thinking about hooking together to make a cold air intake(I need a 90 deg elbow). I would then need to reduce to 2.5" at the intake manifold.
I got them pretty cheap, will be close to price of an bay intake for an ST once I get a filter.

Is this okay, or is it better to be same size all the way?

Thanks!

it moves more air when u go from a large diameter to a smaller one...but there r boundaries...like say from 3 to 1" but u would get more power from wat u wantin to do than say 2.5 tha whole way.
