When I dynoed same day within 20 min. or so of each run, I replaced stock filter and MAF with the KKM and 73mm and got peak gains of 6.8 hp and 6.2 tq with an avg gain of 3.2 & 3.4 respectively accross the rev range. Not 10, but not too shabby either.
Black 98.5 SVT w/ KKM intake, 73mm MAF, ASP pulley, Optimized stock Y-Pipe, 24mm hollow rear sway bar, Magnaflow resonator, Magnaflow mufflers, Roush springs, KYB struts
