APEXi Performance Replacement Panel Air Filter for 1999 Subaru Impreza

A'PEXi Power Panel Filters are designed to be a very easy to install, drop-in solution to increasing power. This product is ideal for those who just want a modest increase and power and do not want to modify their factory intake system.

A'PEXi took power and filtering ability into consideration while making these filters to ensure you get maximum performance and filtering ability. Using a progressive density element provides excellent dust/dirt filtering and also maximizes airflow to the engine. The filter uses a dry style element to prevent any pesky oils from interfering with your factory sensors.

Cleaning Notes: We suggest this air filter should be replaced every 15 to 20 thousand miles, depending on your conditions. Although cleaning the filter is possible, we recommend just replacing the filter when it comes time for a cleaning. Even though this method costs a bit more, it ensures you get the best performance out of the filter.
