Genuine Lexus Filter / Quick Delivery
Initially I had installed non-genuine Lexus filter, which the seller claims it fits Lexus RX. That filter fits (kinda). After installing the air-filter and closing the lid, I could see the edge of the filter because the lid did not close tightly. I am not a mechanic, but I was concerned. Hence, I ordered the genuine Lexus filter from Lexus dealer through Amazon. I paid twice more than non-genuine filter (including extra shipping charge of $10.00). Genuine filter arrived in the FEDEX box (looks and feels pretty sturdy enough to protect the filter) only 2 days after I placed the order. I have just replaced the filter. The lid closes perfectly. Although I spent total $40, for the peace of my mind, it's the money well spent.

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.
