AEM 28-20452 DryFlow Drop-In Air Filter 2008-2011 Lexus GS460 4.6L V8

Vehicle Fitment

• 2008-2011 Lexus GS460 - 4.6L V8 (1UR-FSE) - all trims

Fitment Notes

• Direct drop-in replacement for the factory engine air filter - installs in the existing OEM airbox with no modifications required.
• Dual airbox application - two filters likely required. The Lexus GS460 4.6L V8 uses a dual airbox configuration with one filter per cylinder bank. A complete air filter service for this vehicle requires two units (2x PN 28-20452). Verify your vehicle's airbox arrangement before ordering to confirm the quantity needed.
• This filter is specifically engineered for the 2008-2011 Lexus GS460 4.6L V8 (1UR-FSE). It is not interchangeable with other Lexus GS models equipped with the 3.5L V6 or 2.5L inline-four, which use different airbox filter dimensions.
• This filter will not void your Lexus factory vehicle warranty.
• Sold individually - one filter per package.

Features

• AEM DryFlow Oil-Free Synthetic Media - Up to 99% Filtration Efficiency: The 28-20452 uses AEM's DryFlow non-woven synthetic filter media, delivering high airflow and up to 99% contaminant capture efficiency without requiring filter oil. Eliminates the risk of MAF sensor contamination from oil overspray on the Lexus GS460's mass airflow-metered 1UR-FSE V8 engine, and the synthetic media does not degrade from repeated cleaning cycles the way cotton gauze can.
• Increased Horsepower and Throttle Response: AEM's lower-restriction synthetic media allows more air volume into the Lexus 4.6L V8 compared to the factory paper element - improving throttle response and supporting power gains across the RPM range on the GS460's naturally aspirated V8.
• Tall Panel Design - 2.25-Inch Height: At 2.25 inches tall, the 28-20452 is significantly taller than typical flat panel drop-in filters, providing substantially more filter media volume within the near-square 9.125 x 9.063-inch footprint for improved airflow capacity and extended dust-holding service life matched to the GS460's high-flow V8 intake requirements.
• Washable and Reusable - Lifetime Filter: Clean with AEM filter cleaner (PN 1-1000), rinse with water, air dry completely, and reinstall - no oiling required. Designed to last the lifetime of the vehicle.
• Shed-and-Flow Design: Non-woven media sheds trapped dirt under engine vibration, maintaining consistent airflow performance as the filter accumulates contaminants between cleanings.
• Direct Drop-In Fit: Engineered as a direct dimensional replacement for the OEM paper element in the factory Lexus GS460 airbox - no modifications, adapters, or additional hardware required.
• Will Not Void Lexus Factory Warranty: The 28-20452 will not void the manufacturer's vehicle warranty when used as directed.
• Made in the USA: Manufactured by AEM Induction Systems to precision quality standards.
