COCOAUTO's Engine & Cabin Air Filter Kit provides a direct-fit replacement for compatible Silverado and Sierra models, combining a high-flow engine filter and an activated-carbon cabin filter in one convenient purchase.

This 2-piece kit is made to near-OEM specifications to simplify routine maintenance for 2014–2018 Silverado/Sierra 1500 trucks and many related GM models. The pair restores proper engine breathing and cabin airflow while helping reduce interior odors and particulate exposure. It’s sized and shaped to match original equipment numbers, making installation straightforward for technicians and DIYers alike.

How will this kit affect performance and fuel economy?

Replacing a restricted engine air filter improves airflow into the intake, which can reduce strain on the engine and help recover lost fuel efficiency. While gains depend on vehicle condition and driving habits, a clean filter reduces resistance and supports smoother acceleration.

• High-flow engine filter media to optimize air delivery to the engine.
• Restores throttle responsiveness lost from a clogged filter.
• Helps maintain factory fuel economy when replaced per schedule.

Will the cabin filter really improve in-cabin air quality?

The included activated-carbon cabin filter traps dust, pollen and larger airborne particles while adsorbing many common odors from traffic and exhaust. It helps the HVAC system supply cleaner, fresher-smelling air to occupants without changing factory airflow characteristics.

• Activated-carbon layer reduces odors and VOCs from outside sources.
• Pleated media captures dust and pollen to protect passengers and HVAC components.
• Direct-fit form factor for an easy drop-in replacement.

Which vehicles and filter part numbers does this kit fit?

This kit covers a range of GM full-size trucks and SUVs from mid-2010s model years. It is intended for gasoline and hybrid engines listed; it is not compatible with diesel variants. Verify fitment using vehicle specifics before purchase.

How often should I replace these filters and how easy is installation?

COCOAUTO recommends servicing these filters at least once every 12 months or every 12,000 miles; more frequent changes are sensible in dusty or high-pollen environments. The two-piece set is designed for quick replacement and typically installs in about 10 minutes with basic tools.

• Replace annually or every 12,000 miles; sooner in dirty conditions.
• Two filters included — saves time and avoids separate orders.
• Installation is a simple drop-in for most compatible GM vehicles; basic hand tools required.
