    Air filter location/inlet length?

    Does it mater where the air filter is located?

    I know for best results it needs to be in cold air etc but does it matter how long pipe between the air filter and AFM is?

    Depends on how you get to the new location. Straight piping costs very little compared to each bend - for reference for 63mm piping a single 90 degree bend costs nearly as much as 2 metres of straight piping. So make of that what you will

    i would have thought the shorter the better ( some jap drag cars run open turbo inlets ) but as with everything on a road car you have to make the best of both worlds. if you do happen to find a place to suck cool air not to far from the turbo tell the rest of us !!!

    What about cutting the turbo down and putting in a cone filter from the front grille straight in to the turbo? Crazy i no but its a thought

    If you can make it straight then thats better, as bends reduce flow.

    Someone on here removed fog lamps from Coupe (I think) bumper and used holes as scoops with ducts to direct air to cone filter fitted low down.
    Prob. 10-12 months ago.

    Good ole Skyline stylee lol, yeah I saw a thing on Z20LET owners club I think and the guy did the test with the water and all that and to be honest yes the bends are restrictive and silmilar x amount of straight pipe per bend but it didn't make all that much difference in the end resiults I mean the air gotta go somewhere at the end of the day it isnt going to get jammed or trapped in there lol..

    I'd get one of those 3" aluminium pipes off Ebay and jut bolt in on that mate then take a 4" feed from the grill if you can and place in really close to the filter..

    I did it like this on my Vectras with the filter being strapped straight onto the Throttle body and then the feed cable tied to the side of the filter so the air has to go onto the filter / be sucked through the feed - one of those ebay pipes and then the same principle would be sound.
