today i was looking at my set up and i decided to improve on it more.so i put the filters as far away as possible from the hood where heat gathers.filters stayed cold as ice tonight with ambient at 65.they were cold like i was holding the filter out the window while driving. when i got home and popped the hood,its like they were sitting in ice.i do have fender liner vents as well and the vacuum that is created there,its pulling more air from the oem cold air vents.
after what jordo said,i made sure the intakes would not move.i simply loosened the z1 tubes at the throttle body,and turn the tubes inwards putting the filters right in front of the cold air vents(after modifying them as well) and the tip of the filters are braced on the part of the oem box i retained.
still havnt experienced any power loss and since i buried the filters,my gas mileage also went up even at 100 plus.anyway,im just sharing my project thats working great for me.
.i feel that after i get the pullies,m370,exhaust,and a tune,this car will be scary to drive in 65 degree ambient.
