Air Filter - Denso 143-3112

Engine Air Filter - FTF Air Filter

The engine air filter prevents dirt, dust, and debris from entering the engine, protecting internal components and ensuring the correct air-to-fuel mixture for efficient combustion. Signs of a clogged filter include: reduced acceleration, lower fuel economy, a rough idle, or a visibly dirty filter element during inspection. Replace your air filter on schedule to keep your engine breathing cleanly and running efficiently.
