| Size: | 2.50 in (63.50 mm) |
Improve airflow or replace a worn intake filter with the DC Sports RAF25001 2.5" Open-Top High-Flow Air Filter. Designed for compatible DC Sports intake systems and universal custom intake applications, the RAF25001 combines a reusable oiled cotton gauze filter element with an open-top design for increased airflow and a more aggressive induction sound.
Unlike the closed-top RAF250, the RAF25001 features an open filter top, allowing air to enter through both the sides and top of the filter. DC Sports notes that the open-top configuration breathes more freely and can increase induction sound, making it an excellent choice for performance intake systems, turbo applications, ITB setups, and engine swaps.
The filter uses a 2.5-inch inlet flange and measures 6.25 inches tall, providing a compact package suitable for crowded engine bays. Its oiled cotton gauze media is bonded to a temperature-resistant urethane base for durability under typical engine-bay heat and vibration.

Open-Top Performance Design
The key difference between the RAF25001 and RAF250 is the filter-top configuration:
- RAF25001 – Open Top: Allows additional airflow through the top and provides increased induction sound
- RAF250 – Closed Top: Provides a more directed airflow path with slightly quieter induction characteristics
DC Sports specifically recommends the open-top style for enthusiasts looking for a more noticeable intake sound, including builds where hearing the turbocharger or individual throttle bodies is part of the desired experience.
Washable & Reusable
- The RAF25001 uses an oiled cotton gauze element rather than a disposable paper filter. The filter can be periodically cleaned, re-oiled and reused, providing long service life when properly maintained.
What's Included
- (1) DC Sports RAF25001 Open-Top Air Filter
- (1) Worm-Gear Mounting Clamp
Universal Fitment
- The DC Sports RAF25001 is a universal 2.5-inch air filter. Before ordering, verify that your intake tubing has a compatible 2.5-inch outside diameter and that sufficient engine-bay clearance is available for the filter's 6.25-inch overall height and 6-inch base diameter.
The DC Sports RAF25001 2.5" Open-Top High-Flow Air Filter is an excellent choice for replacing an existing DC Sports filter or completing a custom performance intake, offering reusable cotton gauze filtration, open-top airflow, durable urethane construction and a compact design suitable for a wide variety of performance applications.
