The aFe P5R drop‑in filter for Honda Civic Si (2006–2011, 2.0L) replaces the factory element with five layers of Pro 5R cotton-gauze media housed in a 100% polyurethane boxed frame to increase airflow and filtration efficiency. Deep pleats improve dust capacity and the progressive bump seal provides a leak-free fit in the factory housing. The washable, reusable construction supports repeated cleaning cycles and extended service life.
