I´m thinking to use 4" but I don´t know is that size is huge for my setup or maybe 3.5".............

Thanks

What about 4"

Is too much ...? or is ok ...?

3inch.

I have a 4" wai with a q45 throttle (10" from filter to tb), and a silicone reducer to make the transition. I have a 4" filter (no velo stack ). Oh and my maf element is installed within the pipe (calum ecu made this possible)

Hoping to dyno tune soon, have only street tuned, car feels awesome!

3" at a minimum.

What maf element r u running?

what he said...what are you talking....

so 3.5" is too big...?

That would be fine but, out of all honesty it will not make that big of a difference if any.

I say take both to the Dyno and test . The tq will change in the car and play with length .gl
