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.
