aFe 54-10301 Magnum FORCE Stage-1 Cold Air Intake System with Pro 5R Filter

The aFe Magnum FORCE 54-10301 Stage-1 Cold Air Intake System with Pro 5R media is a direct-fit performance upgrade designed to replace the restrictive factory air box and filter. This system delivers up to 12 horsepower and 17 lb-ft of torque while outflowing the factory intake by up to 21%, resulting in noticeably improved throttle response and acceleration.

Key Features:

• Pro 5R Cotton Gauze Filter: Features five layers of progressively finer mesh cotton gauze media, achieving a 98.6% filtration efficiency rating for superior engine protection and maximum airflow
• 4" Conical Air Filter: Large oval conical design maximizes filter surface area for increased flow and performance
• Durable Heat Shield: Enclosed in a 16-gauge powder-coated heat shield that isolates the filter from engine heat, helping maintain cooler, denser intake air
• Washable & Reusable Filter: The filter is constructed with 100% polyurethane for long service life and can be cleaned and re-oiled multiple times
• Factory Intake Tract Retained: Replaces the stock air box and filter while retaining the factory inlet tube for a clean, hassle-free installation
• Factory Mounting Locations: Heat shield mounts using factory locations — no cutting or drilling required
• Complete Kit: Includes all hardware, clamps, and components needed for installation
• 50-State Legal: CARB exempt (CARB EO# D-550-28) — legal for use in all 50 states including California

The aFe Pro 5R filter's velocity stack design allows air to curve smoothly into the intake tract without loss of velocity, and its progressively finer gauze layers increase dust-holding capacity and filtration efficiency over single-layer competitors. The filter housing is black powder-coated for durability and clean underhood appearance. Backed by aFe's limited warranty and designed, developed, and manufactured in the USA.
