Engine Air Filter vs Cabin Air Filter

Understanding the distinction between the engine air filter and the cabin air filter is essential for owners of the 2018 Alfa Romeo Stelvio. The engine air filter protects the 2.0L turbocharged engine by stopping dirt and debris from entering the intake, which preserves turbo health, sustains the vehicle’s 280-horsepower output, and helps maintain the EPA-rated fuel economy (about 22 city / 28 highway). The cabin air filter, on the other hand, keeps pollen, dust, and road contaminants out of the interior ventilation system so passengers breathe cleaner air and the HVAC system runs more efficiently. At Herb Chambers Alfa Romeo of Boston in Boston, MA, our certified technicians inspect both filters during routine maintenance and recommend replacement intervals that suit your local driving conditions. Both filters play different roles but are equally important: neglecting the engine filter can shorten turbo and engine life, while neglecting the cabin filter affects comfort and air quality. Schedule an inspection or schedule service online and ask about current service specials to keep both systems performing at peak levels.

2018 Alfa Romeo Stelvio Cabin Air Filter

The cabin air filter in a 2018 Alfa Romeo Stelvio is the first line of defense for in-cabin air quality, filtering pollen, dust, and road pollutants that otherwise circulate through the ventilation system. For Boston drivers, seasonal pollen and coastal dust can clog the filter more quickly than average; our technicians at Herb Chambers Alfa Romeo of Boston recommend regular inspection and replacement as needed. We use OEM filters to ensure the correct fit and filtration efficiency and we document every service for transparency. Choosing dealer service brings added assurance: factory-trained technicians, warranty protection, clear pricing, and the ability to use service financing when needed so you can get care now and spread payments over time. We also frequently publish service specials that lower your out-of-pocket cost. Our goal is to deliver a comfortable, healthy cabin and help you avoid downstream HVAC repairs—book a convenient appointment to have us inspect your cabin air filter and recommend the right plan for your driving habits.

2018 Alfa Romeo Stelvio Engine Air Filter

The engine air filter is vital for the 2018 Alfa Romeo Stelvio’s performance and longevity.

At Herb Chambers Alfa Romeo of Boston, our service center in Boston, MA provides quick inspections, OEM replacements, and expert installation by certified technicians who understand Alfa Romeo engineering.
