• Both filters affect comfort and efficiency: a clogged engine filter reduces power and MPG; a clogged cabin filter reduces HVAC performance and can affect air quality.
• Stevinson Chevrolet uses OEM-grade parts and certified techs to ensure both filters meet Chevrolet specifications and warranty requirements.
• For proactive care, schedule service and ask about our service financing options and current service specials.
