Fitment Notes

• Lexus GS400 fitment covers the S160 platform (1998-2000) only; the earlier GS400 (1993-1997) uses a different filter
• Lexus LS430 fitment covers all UCF30 model years (2001-2006) with the 3UZ-FE 4.3L V8
• Toyota Celsior UCF20 uses the 1UZ-FE VVT-i 4.0L engine; UCF30 uses the 3UZ-FE 4.3L - both confirmed fitment
• Toyota Crown Majesta UZS186 fitment applies to 4WD models with the 3UZ-FE engine - confirm drivetrain before ordering
• Does not fit the Lexus LS400 (UCF10/UCF20 1989-2000) - that generation uses a different filter
• Does not fit 2007+ Lexus LS460 - see K&N 33-2381 for that application
• Toyota Celsior and Crown Majesta are Japanese domestic market (JDM) models only

Product Description

The K&N 33-2137 is a washable, reusable drop-in replacement air filter designed for the Lexus GS400 (S160), LS430 (UCF30), and their Japanese domestic market equivalents - the Toyota Celsior (UCF20/UCF30) and Toyota Crown Majesta (UZS186). Covering the 1UZ-FE 4.0L and 3UZ-FE 4.3L V8 engines across model years 1997-2006, this filter seats directly into the factory airbox without any modification and is fully compatible with OEM MAF sensors and engine management systems. Its 4-layer oiled cotton gauze construction delivers more airflow than a stock paper filter while maintaining full engine protection.

Only needing cleaning every 75,000 miles, the K&N 33-2137 is an excellent long-term upgrade for owners of Lexus's flagship sedans and their Toyota-badged counterparts. Whether driving a US-spec LS430 or an imported Celsior UCF30, this filter delivers improved throttle response and efficiency from the legendary UZ-series V8 without voiding the factory warranty.
