If your Toyota or Lexus is leaking oil around the filter housing, this aluminum oil filter housing cap is the fix you need. It replaces the common plastic OEM cap (part number 15643-31050) that can crack or warp over time. Made from durable aluminum, it's stronger and less likely to fail. The kit includes the cap, a new drain plug, and a sealing gasket for a complete replacement. It fits a wide range of models, including Toyota 4Runner, Avalon, Camry, FJ Cruiser, Highlander, RAV4, Sienna, Tundra, Land Cruiser, and Lexus IS, ES, GS, LS, RX, and LX from various years (check the detailed list for your specific vehicle). Installation is simple—just swap it out during your next oil change. Stop the leak, protect your engine bay from oil mess, and ensure a proper seal for your oil filter. A must-have for DIY mechanics and a smart preventative upgrade.
