Subaru cars are traditionally known as gas-sipping fuel misers, but if your Subaru Legacy Air Filter is dirty, it could easily become a gas-quaffing fuel hog instead. A car with a dirty air filter can waste as much as 5% of its fuel - and at today's prices, that can translate into major bucks! Your Subaru Legacy Air Filter should be changed at least once a year, or every 10,000 miles, whichever comes first - even if it doesn't look particularly dirty (you'd be surprised). A dirty air filter can cut off the air supply, causing the engine to run too fast at idle as if the choke knob were pulled out in an older car (in fact, this is exactly what is happening - the engine is literally being "choked" for air).

When a fuel mixture is consistently too "rich," excess carbon can build up on the valves, and unburned gasoline may wind up in the exhaust system - potentially damaging your expensive catalytic converter. Without a working catalytic converter, your car will not only give off smelly, toxic emissions, your engine performance will suffer because the flow of exhaust will be partially blocked as well.

As you can see, a lot of the engine's well being depends of that paper filter, costing less than the price of dinner for four in a fast-food restaurant. Keep your engine running at its peak - get your Subaru Legacy Air Filter for the lowest price.While you're at it, grab some additional items - fuel filters, oil filters, plugs, plug wires, and even some spare belts and hoses for your emergency kit - because when your order totals $50 or more, your shipping is FREE.
