Subaru Legacy Performance Air Intake Systems

The Legacy is comfortable enough to make even the longest journeys enjoyable and it has the room to fit everything you need to take with you so you drive it every day. That means that you want it to be running at its best so you need to give it the right tools which is why we have a range of performance upgrades to suit it. They’re the best way to get the right kind of performance for your driving style starting with our Subaru Legacy air intakes.

Getting the right air intake is important because it’s through that component that your engine gets air from the atmosphere which it uses to run. There are different types including the short ram intake which removes the restrictions put in place by your standard intake so that your engine gets more air or the cold air intake which allows your engine to get cooler air that burns easier. We have the information you need to decide which one suits you the best and once you’ve made your decision you’ll be able to get the right one at a price that suits your budget the best!

    An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a...
    Most aftermarket air filters are constructed from multiple layers of cotton gauze, which are sandwiched between wire mesh that is formed into pleats. The layers of oiled cotton fibers are able to trap dirt particles that are even smaller than the holes in the filter media. The airflow stays consistent between cleanings, for optimal combustion.
    The easiest way to improve airflow to your engine is just by changing your stock air filter to an aftermarket performance air filter. There’s an aftermarket air intake system for every budget and every application. Even if you have a hot rod or custom car, or if your car’s just not listed in a catalog, you can still get a quality system. Everyone, regardless of...
