Toyota Lexus Genuine Air Filter 17801-31110 traps 99.8% of airborne contaminants before they enter the engine intake. Triple-layer paper media prevents grit from scouring cylinder walls. This dry element fits Lexus IS250 and Toyota Mark X engine housings without modification.
Key Features
- Triple-Layer Media: 99.8% filtration efficiency across 240x238x52 mm surface area. Road dust won't reach the internal combustion chamber.
- Polyurethane Frame: High-density perimeter seal prevents unfiltered air bypass. It locks the filter into the Lexus IS250 airbox.
- Japanese Manufacturing: Heat-resistant construction maintains structural integrity under high engine temperatures. The filter won't collapse during heavy acceleration.
- Extended Service Life: 15,000 km maximum durability under standard operating conditions. Heavy BD road dust reduces this interval to 10,000 km.
