Any modification that will give you a performance boost will be something that if SoA can attribute a warranty claim to the mod, they can deny coverage for.Originally Posted by mjboudreaux77
Some dealerships are more lenient than others. Talk with local Subaru owners about "mod friendly" dealerships in your area, or contact the dealerships and ask them. There's a dealership about an hour away from me that will cover most claims, regardless of mods - they probably won't give you a new engine if you blow it due to mods, but the more minor claims (<$1000) they will. There are others that won't touch them.
Bottom line: if you want extra power, you have to understand the risk that you can be denied coverage if the mod caused the problem.
