Secondary air filter

The secondary air filter is part of the secondary air injection system, designed to reduce harmful exhaust emissions, particularly during cold engine starts. This filter cleans ambient air before it’s directed into the exhaust manifold, where it helps burn off unburned fuel particles, thus improving emissions performance.

It is typically located between the secondary air pump and the valve. If the filter becomes clogged or damaged, it can cause reduced engine efficiency, increased emissions, or trigger a check engine light. Routine inspection and maintenance of the filter is recommended.

Replacement can be done with new car parts or used car parts from an auto parts shop or online car spare parts store. Many drivers use a car parts catalog or browse spare parts online to find affordable and compatible parts. Secondhand car parts can be sourced from car breakers or salvage services. For urgent needs, a 24-hour auto parts shop can be helpful. For reliability and proper fitment, it’s best to choose components from the original parts catalog.
