No one knows about my car, a 1999 Legacy SUS. As soon as I say SUS they look at me like I’m stupid. Anyway! I am looking for some upgrade part to boost my HP. More specifically, cold air intake and a performance chips of some kind. The only cold air intake I can find is by Weapon R. My car also has a hood scoop (Obviously not active). How hard would it be to cut a hole in the hood, and make it a forced cold air intake? And where could I find an intake that would fit? What would you do with the air sensor box? I guess thats enough questions for now, I would be grateful for any help.

Check out cobbtuning.com. Don't expect miracles unless you want to pour lots of money into it. You might get a HP or two with a cold air intake...but you'll lose much of your low end power.

 

 

 

I am sure you can cut a hole in the scoop and rig the intake up to suck air from it...someone else might give details into doing this.

 

 

 

 

 

Good luck.

This gets brought up pretty much every day, and you really can't do much to increase hp. Stock Subaru airboxes already flow pretty well, plus they draw cold air out of the fender. A cone filter on a CAI is going to be taking warmer air out of the engine bay. There's also a reason most hoodscoops are blocked off on cars without turbos and top mount intercoolers: water can damage electrical components. I believe there was even a recall on early outbacks to block off the scoops.

 

Really, if you wanted to make a significant amout more power, you could run some sort of aftermarket managament, and change the compression and/or displacement with different heads/gaskets/pistons/rods, advance the timing and put on more aggresive cams, port and polish a bunch of stuff, and run a freer flowing exhaust. By then it'd probably be cheaper to do an engine swap from a WRX or something.

 

Oh, and check out the search function.

its got the 2.5, so look for 2.5 upgrades...... like for the 2.5rs...... its all the same stuff, just in diferent cars....and by the way, i envy you for having that car, i have wanted one since i saw one at the dealer..

Thanks for all the help everyone! I will have to do some further investigation. If you have any more ideas feel free to let me know.
