I was looking at the Perrin fmic with the blow through MAF setup...Has anyone fabed their own blow through setup so not to spend over 1300? It looks like all you have to do is find a maf housing and weld it to fmic piping of your choice....is it really this easy:confused: http://www.jscspeed.com/wrx/intercoolers/perrin_fmic.htm here is the link it saw

yeah, u can buy just the maf mount to weld to the intercooler piping and drill the hole for the maf . Or use reducers and cut the piping and use an ebay intake.
