Purchased a new mass airflow (MAF) sensor from Lexus dealer for 1999 LS400 (with LS430 engine)
177,000 miles and 21 years is not bad service...
Pulled a (MAF) trouble code and cleaned sensor with CRC brand MAF cleaner and the code dissipated, but sensed time to replace.
New sensor was boxed and in a sealed bag but did not include a rubber gasket.
Anyone purchased an OEM MAF sensor from Toyota or Lexus...and did it include a gasket?
Otherwise, does anyone know Toyota MAF gasket P.N.?
Was able to reuse original gasket, but it is 20 years old.
Located this image online...which depicts gasket in question.
The new MAF improved idle, transmission shifting (less "notchy" on acceleration AND deceleration) and more sprited part and full throttle acceleration.
This fits a 430 so not sure if it's correct for your application or not...
It's just a simple O ring. Take the old one to any parts store I'm sure you can find a match.

Using LS430 long block, but all other items, including the air intake components are LS400.
Amended post with this image depicting LS400 gasket for clarification
LS400 MAF Sensor next to MAF gasket. Lexus LS430 parts diagram for air inlet depicts MAF sensor and o-ring seal...
LS400 air inlet assembly depicts MAF without gasket... go figure
Anyone purchase a Toyota MAF sensor for 1998 - 2000 Celsior?
Anyone outside North America purchase a Mass Airflow (MAF) Sensor for their 1998 1999 or 2000 Celsior (VvTi 1UZ-FE) (LS400)?
If so, did the new MAF include the replacement rectangular rubber gasket?
