The air filter is housed in a rectangular plastic box on the passenger side of the engine bay, toward the front. A large intake hose runs from the box to the throttle body, and the box is secured with clips or screws for easy access.
In 2015 Silverado models with various engines, the air box generally sits on the right side of the engine compartment (the passenger side when facing the truck). Access is gained by releasing the lid’s fasteners, lifting the cover, and replacing the filter with the correct orientation before reassembling.
Location in the engine bay
The air filter box is a rectangular black housing located on the passenger side of the engine bay near the front fender. The lid is held down by clips or screws, and a thick plastic intake tube connects this box to the throttle body further into the engine, guiding filtered air into the intake system.
How to replace the air filter
The following steps outline how to locate, remove, and replace the air filter on a 2015 Silverado.
- Park safely, turn off the engine, and open the hood. Let the engine cool if it was running.
- Locate the rectangular air filter housing on the passenger side of the engine bay near the front wheel well.
- Release the clips or remove the screws that secure the lid of the air box.
- Lifting the lid, remove the old air filter and note the correct orientation for the new filter.
- Clean any debris from inside the housing with a clean cloth if needed.
- Insert the new air filter, ensuring it seats evenly and matches the orientation of the old filter.
- Reinstall the lid and secure all clips or screws firmly; reconnect any hoses that were moved.
- Start the engine to verify there are no unusual noises and that air intake connections are properly sealed.
Concluding: Replacing the air filter is a straightforward maintenance task that helps ensure the engine receives clean air and maintains performance.
Tips and considerations
Use the correct filter size for your engine (check the owner’s manual or a parts retailer for the right part number). In dusty or harsh conditions, inspect and replace more frequently to prevent reduced air flow and potential engine wear.
