aFe Momentum Pro 10R Replacement Air Filter 20-91147

Pro 10R Filter Media: This filter features ten layers of pre-oiled cotton gauze media to provide maximum Longevity. Its progressive layering allows the filters to flow at high levels even when dirty, while its inverted top makes for more filter surface area, resulting in longer service intervals. This media is only available for select diesel truck applications. Pro 10R filters are easily recharged with aFe's POWER CLEANER and blue air filter oil. Rounded Deep Open Pleats: aFe POWER performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. Its surrounded by expanded metal that provides additional protection, preventing filter collapse and direct impact. 100% Polyurethane Base & Top: This aFe POWER performance air filter is constructed with a polyurethane base and top. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape. Innovative Design: The Momentum series' patented interface uses a single clamp around the housing to secure the filter to the housing. This simple design allows for easy filter maintenance and replacement. Emissions Disclaimer: This product does not require a CARB EO#.

The aFe Momentum Pro 10R replacement air filter, part number 20-91147, is designed for select diesel truck applications using aFe Momentum intake systems. Its ten layers of pre-oiled cotton gauze provide high airflow while helping capture contaminants before they reach the engine. The progressive media design maintains strong airflow as the filter loads with dirt, while the inverted top increases usable filtration area to help extend service intervals.

Rounded, evenly spaced deep pleats maximize filter surface area for improved airflow and increased dust-holding capacity. Expanded metal surrounding the media helps protect the filter and resist collapse under demanding operating conditions. A pliable polyurethane flange with an integrated bump supports a secure fit, while the 100% polyurethane frame and top maintain their molded shape through repeated engine-bay heat cycles.

This washable and reusable aFe filter can be cleaned with soap and water, then recharged using aFe POWER CLEANER and blue air filter oil for multiple maintenance cycles. The Momentum interface uses a simple single-clamp design to secure the filter to the intake housing, making filter inspection, cleaning, and replacement straightforward. The filter is not CARB approved and does not require a CARB EO number; verify application-specific emissions requirements before installation.
