Engine Air Filter vs Cabin Air Filter

The difference between the engine air filter and the cabin air filter on a 2018 Nissan Frontier is more than location — each serves a distinct purpose. The engine air filter protects the V6's intake system from dust and debris, directly affecting horsepower, throttle response, and fuel economy. The cabin air filter protects occupants from pollen, dust, and road particulates and keeps the HVAC system running efficiently. Maintaining both filters prevents strain on the engine and HVAC, reduces the risk of costly repairs, and improves daily driving comfort. At Larry H. Miller Nissan Mesa in Mesa, AZ, our certified technicians use OEM parts to ensure proper fit and function. We back our work with dealership warranties, and any warranty-covered repairs must be performed at a certified dealership to maintain coverage. For transparent pricing and options, view our service specials or schedule service online; our team will inspect both filters and recommend the ideal service plan to protect your Frontier and your investment.
