Keep your Lexus running smoothly with this A-Premium engine air filter! It's designed to fit a range of models, including the GS350 (2007-2011), GS430 (2006-2007), IS250 (2006-2013), and IS350 (2006-2015, including C F Sport/C Model). This rigid panel filter directly replaces OEM part numbers like 17801-31110, AF3998, PA5798, and others. Measuring about 9.33 x 9.25 x 2.15 inches, it fits the front side of your engine and uses fine filtration media to trap debris without restricting airflow. That means better engine performance, improved efficiency, and protection from harmful particles. Experts recommend replacing your air filter every 12 months or 12,000 miles (or as per your vehicle's manual), so having a reliable filter like this on hand is a smart move. Easy to install and built for durability, it's a straightforward upgrade for your Lexus.
