any injen? cause i know my mate has a V2 sounds good on his EG but who cares lol i want more performance then sound, sound i can use an ehxaust yeah? kinda hijacking the forum but, you people seem to know what your on about here thats all.

havent had no experience with the aemv2 , the fujitas are pretty cheap on ebay us

i had a look at using semi rigid aluminium ducting
kinda cheap at $50 for 3m
Havent had time to do more than a 10 minute check in bunnings, new yrs celebrations and recovery time..
i have found another pvc drainpipe part that fits nicely in the bottom of the airbox and has a 70mm id which should be ok, but ive also got a 90mm one im planning on modifying. just to get all geeky... here's how i'd start thinking about it from a numbers point of view
1.8L n/a engine consumes 1.8L of air every 4 revolutions, call it 2L to account for leakage, so at 8000rpm (my redline) the engine needs 4000L of air (per minute) or 240Kl/hr. To roughly calculate the intake area required, V=A.v which says that for a 90mm pipe opening perpendicular to the airflow at 40km/h (igoring friction losses and any intake funnel effects) enough air will be entering the airbox to satisfy the engines demand. For a 70mm pipe this speed is more like 65km/h.
All I've found at bunnings so far is ally 100mm kitchen ducting... If i can find a way to mount it, access cool air without major bends then i will use that with an adaptor to fit the airbox, with that kind of intake area, I doubt there will be much air drawn in from the engine bay, instead it might provide some additional cooling to the ABS unit

For the extra few hundred tbh i'd prefer something else personally.
