Engine Air Filter vs Cabin Air Filter
The 2018 Lexus RX 350L uses two distinct filters with different roles: the engine air filter ensures clean air enters the 3.5L V6 to maintain the vehicle’s 290 horsepower and efficient combustion, while the cabin air filter protects passengers from allergens, dust, and road debris. Regularly servicing both filters preserves performance, reduces emissions, and improves interior comfort—critical benefits for Colorado drivers using their RX-350L in variable conditions. At Stevinson Lexus of Frederick we explain these differences clearly, inspect both filters during routine maintenance, and recommend OEM replacements when needed.
