Thread: 3.5 intake

so would a q45 tb and q45 maf use 3.5 or 4 inch piping?

I think 3.5

Just got the maf

We have seen pretty serious gains on the K-series cars when going to a 3.5" Intake Arm and a decent sized throttle body.. it should definitely benefit you guys with bigger cams!

That's good to know

wonder if a 3.5" intake pipe would see me any gain?

stock IM
70mm tb (75mm where it joins the pipe)
e60 maf - 3"
ve/e60/n60 3" pop charger

lol, i know i need a custom intake. but...

have 3" intake pipe now.

peace

3.5" Intake pipe on an N1 Throttle Body

Is that some sort of adapter for the Q45 TB??? I have a stock xcessive manifold for a VE TB but am looking to upgrade and thought the only option was to send it in to get the q45 tb bracket welded on.

Here's a question - where do you guys find these 4" pipes? I have a cold air intake, 3.0" inch to the N60 MAF then a 3.5" from MAF to throttle body. The car made 206hp with the warm air intake setup before I changed to cold. So I'd like to find some 4 inchers, go dyno and see what the difference is.
