I'll likely go clear corners eventually - for now I am fighting the pedal-box conversion and focused on getting the brake-lines in so that I can go and drive this thing...!
I wouldn't do the dryer hose thing - will look like shei-it if you ask me and I don't know what the insulating factor is - may make it worse...! BTW - Greg's coned-filter is MUCH better than the run of the mill K&Ns, or K&N knock-offs out there...
IF anything - Greg's tubes look better and work well, but even then - question the gains from just doing those with a K&N style filter, when you still have the restriction of the AFM up-stream - and not to mention - an in-ability to capitalize on any additional air (no way to control fuel...)
I know Greg won't agree with me on this one, but either find a way to get rid of the restrictive AFM (after-market engine-management system like we did), or at the very least a larger BMW-type BOSCH AFM - the restriction is upstream - not in the airbox.
I get this question a GREAT DEAL; "open intakes" - larger intakes - K&N filters etc - think of it this way - really you should start with the mechanical unit and work forward - not the other way around! If there is not an increased ability to process
more air then it is useless! Even forcing it in, if you are not going to increase fuel-supply, you're pissin' in the wind and even then, you need to cool it, process it, get it out faster etc. (The air, not the piss...
Once you have increased the mechanical unit's ability to process more air/fuel mixture (bigger displacement, higher compression, more cam, higher-flowing heads, free headers etc - then
additional airflow in
, makes sense...
Heat-shielding works either way.
