Lower Air Box

The Lexus F-Sport Lower Air Box (PTR03-53081) is a genuine Lexus accessory designed to replace the stock lower air box, functioning as a cold air intake component. This F-Sport lower air box is compatible with a range of Lexus IS models, including the IS250 and IS350. Specific fitment includes: - 2006-2012 Lexus IS250 Base models with the 2.5L V6 - Gas engine. - 2006-2012 Lexus IS350 Base models with the 3.5L V6 - Gas engine. - 2010 Lexus IS350 C models with the 3.5L V6 - Gas engine. It's important to note that while some sources indicate fitment for 2006-2012 Lexus IS models, other information suggests potential compatibility with later models such as 2014-2020 IS350 with no modification needed. However, this specific part number (PTR03-53081) is explicitly listed as NOT fitting a 2021 Lexus. Always verify fitment for your specific vehicle year, model, and trim.
