I know there has been debate over the K&N air filter in previous threads. In case anyone is interested, they now have one available for the 2010 RX350.

Just FYI.

 

Yup! I just installed mine today.

I ordered a K & N filter through my local Canadian Tire here in Vancouver. Lordco had no listing yet. The person I talked to at CT said they have an account with K & N and could order one. She said it would likely cost $80 to $100. I asked them to get an actual price and it turned out to be $55, which you have to pay in advance for a special order. I've seen them online for $49 + $20 shipping, so Canadian Tire is a good deal.

Installing the filter improved the dismal city mileage slightly. But then, the current filter sucked up a lot of dust during a summer road trip.

 

More air = more dirt.

 

Which CT did you order it through, and how long did it take? Thanks!

 

Does the RX350 and the RX450 share the same air filter?

 

Yep they should call it the K&N dirt intake lol. I am using a Wix Paper filter for my car, and thats what I recommend.

 

I am asking what is wrong with the OEM filter for this car?

 

i wish true flow made a filter for the RX

 

Billy, there's nothing wrong with the Lexus OEM filter; there are better ones out there. However, if you require higher quality or push your car harder than normal (hills, dirt roads, etc...), there are solutions available. Another solution is to change your filter more often than specified. It's a personal preference and decision.
