aFe Pro 5R Drop-In Air Filter Subaru WRX / STI 2008-2021 | 30-10161

If you're looking for maximum airflow from a drop-in filter for your 2008 - 2015 WRX, the aFe Pro5R is your best bet. This oiled performance filter, which replaces the OE filter, allows a lot more air to flow through. It features five layers of cotton gauze media with a progressively finer mesh. The filter is washable and reusable for multiple cleaning cycles. Its round - topped pleats offer a large surface area, and the deep pleats can hold a lot of dust, meaning you can go longer between cleanings. The aFe Pro5R also ensures a tight, leak - free seal throughout the filter's lifespan. Part #: 30 - 10161

Using the aFe Pro5R air filter is easy. Just remove your old filter and replace it with this one. Make sure it's properly seated to ensure a good seal. When it comes to maintenance, this filter is washable and reusable. You can clean it when it gets dirty. However, make sure to use a suitable filter cleaning kit to maintain its performance. Avoid using harsh chemicals that might damage the filter media. Regularly check the filter for any signs of damage or excessive dirt buildup. If you notice any issues, it might be time to clean or replace the filter.
