no it doesn't work. I tried. you either have to do alot of moding to it or you can change it to a cool air intake, buy using 1 of the tubes. the only problem with that is your only using half of the damn thing plus it basically worthless. you'll be making a really nice sound when you accelerate, sounds awsome but becides that you won't be gaining really any hp.. maybe 3-5 if your really lucky. overall, i'd say keep looking for a 2.5, you just have to search really hard, you'll find a few. as far as the engins being built the same, they arn't or at least set in differently, go look at some pics online, between the 2. good luck bud

 

NO! this topic has been run into the ground! a intake for any mass air RS will work, with some modding (yes i have done this for the sceptics) but there are currently NO intakes specificly for the 05 RS
