Lexus, you have never let me down!
I asked for original equipment and that is what I received. Delivery only took a few days from a dealer mid way across the country. A perfect FIT.

Great Filter - shipping needs to be improved
The air filter was great and would recommend the OEM filter. My only
Complaint is that they didn’t ship it in a box but only slapped on a shipping label on to the original air filter box.
It took about a week to get to me (Arizona) and the box looked really beat up and luckily the filter was still ok by the time it got to me. Recommend putting it in a box to protect it from damage.
