Hey Lexus ES300 owners (1999, 2000, 2001 3.0L models), if you're dealing with a cracked or dry-rotted air intake hose, this 2-pack from INFINAUTO is just what you need. This is the hose that connects your air intake box to the throttle body – super important for engine performance and fuel economy. It's a direct, non-OEM replacement that matches the OEM specs and fits perfectly (OE number is 1788120100). Made from durable, high-temperature resistant rubber that's built to last and resist cracking. The inner diameter is about 5.5 cm (2.16 inches), and the overall size is roughly 6.3x10 cm (2.48\x3.94\). Installing it is pretty straightforward – just lubricate the ends, get your spring clamps ready, and slide it into place. Comes in a handy 2-pack, so you have a spare or can do both sides if needed. A simple, affordable fix to restore your car's driveability and keep that engine breathing right. No more whistling or unfiltered air leaks!
