The normal stock air filter is a small and light component used to remove solid particles from the air before it enters the engine, causing additional wear. The tubular-shaped container is colored an almost black violet, with other parts colored a metallic silver. It costs DM 20, and can be purchased from Laika Dealerships, or found in Abandoned Cars and in the player's Home. The normal stock air filter is used as part of the tutorial with Uncle, and will be the first type of air filter the player will install in their Laika 601 Deluxe.
