the setup thats on there is temporary but its a 4inch to 3.5 inch elbow, a picece of 3.5inch aluminum tubing, camaro MAF, camaro IAT(i took the rubber grommet out of the camaro airlid and just drilled a hole in the aluminum tube and stuck it in there) and some cheapy autozone airfilter. im gonna switch it to a 4inch MAF from a vette with an integrated IAT and normally i just use thin wall PVC(local home depot or lowes) that you would use for drainage (and people make fun of me lol but its cheap, doesnt retain heat and easy to replace). i intend to put a much larger airfilter under the inner fender(where the charcoal canister used to be) to take in colder air.
