yeah but on a rolling road its gonna show loss cos uv got no cold air blowing in to the engine bay cos the car isnt moving they dont produce much or any loss if u have one or two codl air feeds n, mayb from a still start but not from while moving
do u no there are 2 cold air feeds on the mg zr k&n generation 2 one connects onto the original air feed and there is another one that connects to the side of the box. oh well i will wait n see i am gettin 2moro if its shit then it will go on ebay. lol
Mines just been on the rollers and yes there is a cold air feed (or should be ) in the form of a large fan that speeds up with the mph of the car so as to give the correct air flow at the correct mph, i have a k/n cold air feed (supplied in the 57i kit) and a mod from the original mg cold air feed).
