Has anyone added skid plate (Part # PT93860240) to their GX 550 Premium + or Luxury? My Audi A3 has the cleanest engine bay, because Audi includes the lower engine cover (splash guard) as a standard accessory. I would think, adding the Lexus genuine accessory PT93860240 front skid plate to the GX 550 Premium Plus will help in keeping the engine bay cleaner by providing a substantial barrier against road debris, water, mud, and dust, much like the lower engine cover on your Audi A3.
