    Subaru Catch All TSB Regarding Modding

    Since some new members (and even old members) might not be aware of Subarus Warranty agreement I figured I'd post up this TSB I found.

    It's pretty clear in what Subaru is willing to accept as far as mods to the vehicle.

    Nice find.

    Do they really need illustrations of an aftermarket intake, exhaust and BOV? Or show what a dirty air filter looks like?

    Very good find Craig.

    It's a good thing I don't do any of that.

    No.

    They are saying if you have a downpipe which creates more then stock power they arent going to fix your drivetrain parts if they fail.

    99% of the time catbacks are fine. They dont create any more power then usual. Subaru is usually good with warranty stuff with a CB as long as the CB doesnt OBVIOUSLY cause an issue.

    So is that saying that you cannot put a after market intake on it? What about the SPT intake? So what mods can you do that won't void your warranty?

    I guess I'll just lock this as it's really not the place to answer questions it's just informative.

    SPT parts are fine.

    Mods that you can do to not "void" your powertrain warranty would be any SPT part or MOST catbacks. I havent heard of any cases where a catback voided anything with the powertrain.

    As far as intakes...other then the SPT unit (since it's approved) they could make a logical argument that it caused more stress on the motor, turbo, and I'm sure they'd even grab saying more power then the stock gearbox was ment for.

    These are CUT and DRY FINAL findings. Each warranty case is handled on an individual basis.
