        Description:

        The math is simple: More oxygen in your motor equals more power at your rear wheels. Unfortunately, a stock air filter housing unit's restrictive design subtracts air, stealing valuable horsepower every time you hit the pedal. That's where K&N XStream Round Custom Air Filter Assemblies step in. These universal filters replace the top of your air filter assembly, opening up an entirely new route for energy-rich oxygen to rush into your powerplant.

        The same tried and true technology that K&N developed for their world-renowned air filters is used in your K&N XStream Round Custom Air Filter Assembly. 4 to 6 sheets of pleated and oiled cotton gauze are layered between 2 sheets of aluminum wire mesh. This ingenious setup stops dirt, dust and other harmful particles, all without blocking clean, power-enhancing air from flowing freely to your engine. The results: more power, more fuel economy, and more fun driving.

        K&N XStream Round Custom Air Filter Assemblies come in 3 universal sizes to fit most carbureted engines: 9", 11" and 14" diameter. Plus, the 14" models come in 3 wild colors: red, blue and chrome. For the ultimate performance boost, you can also get a complete filter assembly along with your XStream Round Custom Air Filter Assembly top. Million Mile Limited Warranty.

        With not alot hood space I opted for a small drop base that would maximize my air intake. I really like the set-up and with my car being a burgandy color it matches with the filter pleats. Nice little touch of accessory and performance.
