2014 to 2018 Chevrolet Silverado 1500 5.3L engine air filter

Reference guide. A general procedure compiled by Wrenchpit, not a first-hand write-up from one owner's vehicle. Torque figures, capacities and part numbers vary by model year, engine and trim — check them against your service manual and the labels on your old parts before you rely on them.

Applies to roughly 2014-2018 model years. Filed under 2016 because a guide carries a single model year.

Change the engine air filter on the K2XX Silverado at 30,000 to 45,000 miles depending on how dirty the environment is. GM's official interval is 45,000 miles for normal service and 22,500 for severe service. Any truck that spends time on rural gravel, farm work, or towing behind construction trucks is in severe service whether the owner admits it or not.

A dirty air filter on the 5.3L will not throw a check engine light on its own. What you get instead is a slow drift in fuel trims as the MAF reads lower airflow than the engine is actually pulling, and eventually a rich condition that costs 1 to 2 mpg. Pulling and looking at the filter every oil change is the cheapest inspection you can do on this truck. If sunlight will not pass through the pleats when you hold the filter up, replace it.

Cost runs 15 to 25 dollars for the ACDelco A3110C. The A3181C is a wider filter that fits certain LT and Z71 airbox variants across the same year range, so verify what came out before you order. Both filters are commonly stocked at any auto parts counter and the AC Delco variant is worth the extra couple of dollars over the cheapest store brand.

Do not run K&N or oiled cotton filters on the 5.3L. The MAF sensor on this engine is sensitive to oil migration, and even a properly cleaned and re oiled cotton filter will send enough oil vapor downstream over 30,000 miles to foul the MAF hot wire. That leads to a P0101 code and 200 dollars in cleaning or replacement to fix a problem you did not have on a paper filter. Dry synthetic media is fine if you want a lifetime filter that can be washed and reused, but skip the oiled cotton style.

If the airbox lid will not seat cleanly, the intake tube behind it has slipped off its lower fitting. Reach behind the lid and confirm the tube is fully seated on the airbox outlet neck before you fight with the clips again.

Check your part numbers against the labels on the old filter and the airbox lid before you order. Trim and cab configuration shift the airbox size on this truck, and the A3110C versus A3181C decision is easiest to make by comparing the old filter frame dimensions.
