Hay Munk, I thought it was just me making my car faster with offcuts and snot. I made an air ram by removing head lamp glass cutting hole in back of it. Then used an old air filter box ( cone like shape) which i riveted to the headlight, Fixed that to 8" of 110mm soil pipe ( domestic poo pipe, new and unused i may add). Then i had the quandri of reducing down to sweetly lip on to the MAF sensor. After turning the old workshop upside down i found an old roadcone. PERFECT. Cut it to the correct appature then cut in to the ends to make flaps then jubilie cliped on to the MAF
