    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.

    2008 Audi A4 | Posted by Oscar | (Oxnard, CA)

    I bought this item for a Audi a4 I love the design I really like the look and most of all the sound that comes out and it adding horsepower to the car overall the installation was very easy and the good thing is. If you're from California it comes with a car sticker so you don't have the problem when doing your smog. If you're thinking of purchasing a cold air intake system this is the way to go I definitely recommend this.
