Great question Bob. I've got a 2010 XT also and will be paying attention to the answers. I don't think there is much out there yet for the new Forester, but I'm guessing we will get some advice on using WRX/STI parts.
What fourortwowheels said would be a good starting point but unfortunately Subaru does not make any of these parts. Any engine mgmt will compromise the warranty. If you do a stage 2 tune the ecu will record the change and "if" you have problems Subaru will and probably deny coverage. This comes from my dealership, which, was very heavily into modding subbies. They have repeatedly told me that SOA is cracking down on modifications and not allowing warranty repairs. It is not that the forester cannot handle these changes, and some are even more efficient than stock (as fourortwowheels said), but it may void your warranty. Proceed at your own RISK.despite what your buddy told you about warranty work there is proof stating otherwise. then again if hes your service manager, maybe he'll stand by ya, nothing is a definite when venturing down this road... anything you mod, has the potential of voiding your warranty whether its an spt product or not. that being said, your first mod should be some sort of engine management because the stock tune on these cars just sucks.
id keep it simple though and stick w/ a stg2 setup which will consist of a downpipe(+ maybe catback exhaust) and tune. that should give you enough power to start and you can move on2 other parts of the car.
^^ Accurate info, and good advice.What fourortwowheels said would be a good starting point but unfortunately Subaru does not make any of these parts. Any engine mgmt will compromise the warranty.

Now what to do. You can change your A/F to something like a K&N but you will not pick up much of anything except a bill for the item. Enhancing the air flow of the system requires you to do a CAI, down pipe and cat back exhaust. All of those items are not yet made by Subaru for the MY09,10 forester (certain items are made by SOA but are not designed for the forester. Case in point, godwhoismike, a member here, had his dealer put on, purchased there, the SPT cat back exhaust made for the WRX. It is a direct bolt on. The item failed, a weld, and he was denied warranty and SOA said if any other problems develop, engine, it would void the warranty (there is a thread here on the subject)). Since you are a SOA consultant you can probably check into this better or have the service mgr check deeper with SOA. If you want to change something I would focus on suspension for now. You can change the sway bars which should give you much better handling without compromising the suspension or warranty (this again is an "if" but I feel a safe one). These are also somethings I wanted to do to my FOZ but when I realized the possible implications I decided against them. That's why I buy new. I want a warranty. Sorry to be the bearer of bad news but that's how it is (at least from my research and the information I have been able to attain). As I said earlier......proceed at you own risk unless your buddy/dealership will personally guaranty the work and parts. If that is the case have at it but get it in writing. There are also accessory items to add on to the FOZ to increase the creature comforts and appearance of the forester, but that's it for now. Good luck with your new Forester.......it's a great vehicle and I do enjoy mine.
That's something that seems to vary from dealer to dealer. May want to ask at your local dealership and see if any of those SPT parts will affect your warranty.I did add a few accessories which will be installed this week. I agree and will focus on the suspension first (sway bars) and tires. I need to sell my Tacoma before I add the SPT intake, heat shield and exhaust. I will also make sure this doesn't void my warranty. I'm new to adding mods to Subaru's and have a question. Are the warranties of the STI, WRX, Legacy GT and Outback XT covered when the SPT performance accessories are added by the dealer? :icon_question:
Thanks

Bob, Even though it looks as the SPT intake is for the Forester it will NOT work. The MAF sensor will not attach to the unit. Another member here tried and purchased it, but no go. After he spoke in-depth with SOA they confirmed it will not work. This was several months ago and I believe nothing has changed. Return it if you have purchased it already. As far as the warranties go....as long as the parts are for a certain vehicle, as deemed by Subaru, then yes the parts carry a warranty. I also believe the parts will carry the warranty even if installed by yourself as long as the install is done correctly, may be limited to 90 days, not sure.I did add a few accessories which will be installed this week.

I talked to the service manager today and he said if it is sold by Subaru (SPT) then not a problem. If it is aftermarket you take your chances.
Bob...
To the best of my knowledge and all my searching and inquiring Bob, you need anything made that will fit a MY08+ WRX. That being said the only item that is made is the cat-back exhaust. There isn't a down pipe or up pipe made by Subaru as of yet and I don't believe there is one for any year that is made by Subaru (I could be wrong). Something else you may not be aware of is that when the SPT exhaust has been put on other MY09XT Fozzie's, it produces a drone at highway speeds that has turned some people off. Realize the WRX has a trunk which the Forester does not creating loud resonances in the passenger compartment. Other than that Subaru really doesn't make anything to increase engine performance, for that matter nothing for suspension either other than a (new) front strut tower brace, that has a rubber bushing in the middle of it (makes no sense, I won't use it until somone else reports benefits). Since it seems as though you are willing to take chances there are plenty of aftermarket items that will work and are very good products. You can search through the "members gallery" and look to see what some that own the SH model have done. That's my take on it.........Best of luck with the mods.If I were to go ahead and order SPT parts, which would be the best bang for the dollar. What years parts work from the WRX-STI (exhaust- up pipe)?
Thanks

Like Hot09XT said, the SPT exhaust will work. I would not use the SPT intake designed for 05+ LGTs even though most likely it will work with your car.If I were to go ahead and order SPT parts, which would be the best bang for the dollar. What years parts work from the WRX-STI (exhaust- up pipe)?
