aFe 20-91206R MagnumFLOW Pro 5R Oval Conical Air Filter Momentum Replacement

Vehicle Fitment

• Universal - Replacement filter for aFe Momentum GT and Momentum series cold air intake systems using an oval conical housing; also suitable for custom intake builds requiring these dimensions

Fitment Notes

• This is a universal oval conical filter - verify your Momentum housing or custom intake accepts a (6-3/4 x 4-3/4) IN oval flange before purchase
• Confirmed replacement filter for aFe Momentum GT cold air intake systems using the same oval housing size
• Pro 5R (oiled) media requires re-oiling with aFe blue air filter oil after cleaning - not for use in MAF-sensitive applications without proper oil application
• Not CARB legal - not for sale in California or other CARB-adopting states

Features

• Five layers of progressively finer pre-oiled cotton gauze Pro 5R media for maximum airflow and performance
• Progressive layering allows the filter to flow at high levels even when dirty for extended service intervals
• Inverted top design maximizes filter surface area compared to standard top configurations
• Rounded evenly spaced deep open pleats increase usable surface area and dust holding capacity
• 100% polyurethane base and top resist heat cycles without cracking, warping, or distorting
• Retention groove locks into compatible aFe Momentum series housings with zero hardware
• Washable and rechargeable with aFe POWER CLEANER and blue Pro 5R air filter oil
• Ideal for street and track applications - maximum airflow at the cost of oil maintenance

Product Description

The aFe POWER 20-91206R is a universal Pro 5R oval conical air filter designed as the replacement element for aFe Momentum GT and compatible Momentum series cold air intake systems, as well as custom intake builds requiring an oval flange in these dimensions. Its five-layer progressively finer pre-oiled cotton gauze Pro 5R media delivers maximum airflow performance - aFe's highest-flowing filter media option - making it well suited for street and track applications where peak flow is the priority.

The inverted top design and rounded deep open pleats maximize usable filter surface area, extending service intervals even as the filter accumulates dirt. The 100% polyurethane construction holds its shape through repeated heat cycles, and the retention groove allows it to lock directly into compatible aFe Momentum housings without additional hardware. Maintenance requires cleaning with aFe POWER CLEANER and re-oiling with aFe's blue Pro 5R air filter oil before reinstallation.
