Which Filter is Right for Me? Pro 5R vs Pro DRY S:
Pro 5R Air Filter:
The Pro 5R filter is designed for maximum performance, featuring five layers of progressively finer cotton gauze media. Pre-oiled for enhanced airflow, this filter excels in delivering high-flow air, resulting in the highest power gains in most cases. Ideal for both street and track use, its large 7-1/2” tall design with a 360-degree radial flow and 3-1/2” flange provides ample air supply to the engine. The inverted top increases the surface area, ensuring longer service intervals.
Pro DRY S Air Filter:
The Pro DRY S filter offers a more convenient, oil-free alternative with three layers of synthetic media, making it ideal for street and light off-road use. Like the Pro 5R, it features a large 7-1/2” tall 360-degree radial flow and a 3-1/2” flange. Its progressive layering delivers excellent filtration efficiency and dust-holding capacity without the need for oils. The inverted top also increases surface area, ensuring longer intervals between services.
Comparison:
The key difference between the Pro 5R and Pro DRY S filters lies in their media type and intended use. The Pro 5R's five-layer, oiled cotton gauze media provides the highest airflow and power gains, making it perfect for high-performance street and track use. On the other hand, the Pro DRY S, with its three-layer synthetic media, offers the convenience of oil-free maintenance, best suited for regular street driving and light off-road conditions. Both filters feature a large surface area and similar dimensions, but the Pro 5R is tailored for peak performance, while the Pro DRY S focuses on ease of use and filtration efficiency.
Unique One-Piece Housing:
Crafted from heat-resistant cross-linked polyethylene (XLPE), this one-piece sealed housing integrates a patent-pending filter-to-housing interface, reducing the number of components for a streamlined installation. A large clear sight window allows for quick and easy filter checks without disassembly. The system pulls in cool air through a Dynamic Air Scoop at the front and an additional inlet in the fender well.
Dyno-Tuned Intake Tube:
The intake system includes a high-quality, computer-designed, and dyno-tuned tube, optimized for maximum power gains and precise fitment. Made from heat-resistant and durable XLPE material, the tube is built to withstand high-performance conditions.
Hassle-Free Installation:
Featuring stainless-steel clamps and silicone couplings for added strength and durability, Momentum intakes are designed with fewer components, ensuring a quick and easy installation process.
