it's $42 last time i checked on newlexusparts.com:
Collision Catalog - 1995 - Lexus - Es 300
Engine / transaxle, Air intake, Hose, Hose - 1994-96 1 $41.28 $0.00 $41.28
it's easiest to just remove the entire intake hose along with the air filter lid and MAF sensor in one piece then take them apart when they're out of the engine. this way you can also clean the MAF sensor and throttle body with some o2 sensor-friendly spray.
