With exposed hardware and a motorsport inspired design, this Stage-2 Si's aggressive dual air filter design is sure to draw attention.

Pro 5R Filters: Large Five Layer Performance Air Filters:
Dual 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. They provide your engine with the largest amount of high-flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and/or track use. Their inverted tops make for more filter surface area, resulting in longer service intervals.

Pro DRY S Filters: Large Three Layer Performance Air Filters:
Dual 360-degree radial flow air filters feature our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Their progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Their inverted tops make for more filter surface area, resulting in longer service intervals.

Unique Housing With Cover:
The smooth housing, constructed of cross-linked polyethylene (XLPE), is used to minimize the number of components and ensure the coolest air intake charge available. The housing utilizes the factory OE air inlets. A vacuum-formed removable cover seals the system, ensuring cool air delivery to the engine, but can also be removed for extra air flow if desired.

Dyno-Tuned Intake Tube:
This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat soak resistant and extremely durable.

Hassle-Free Installation:
The computer designed system utilizes factory mounting locations, minimizing the use of unnecessary hardware and ensuring a perfect fit every time. Its innovative design makes for a hassle-free, direct bolt-on installation process that requires no cutting or drilling.
