The engine air filter protects the hybrid powertrain's 3.5L V6 from particulate contamination, preserving 338 horsepower output and preventing abrasive wear that can shorten engine life. The cabin air filter protects occupants from pollen, dust, and urban pollutants, keeping the climate control system efficient and the passenger compartment comfortable. At Park Place Lexus in Plano, TX, our certified technicians inspect both filters during routine maintenance and recommend OEM replacements when needed. Using genuine Lexus parts ensures correct fit, filtration performance, and continued warranty coverage.
