NP, I learned the hard way by trusting this forum without checking I wish I recorded my installation when I found out the recommended filter won't fit. It would have been a 60 second video with a long expletive beep

 

Where can I buy CF12157 online? It's not available on Autozone, Walmart or Amazon as they advertise.

 

 

You can also try RockAuto which has a after market cabin air filter for less than $10. And yes it is also carbon filter without the Fabreeze smell.

Update: I received and installed Premium Guard cabin air filter. It's exactly the same size as OEM, fits perfectly.

 

I got my air and cabin filter today from mylparts.com. Use CL5 in promo code for a 10% discount. There is confusion over the filters. A lot of sites are showing the 2013-15's fitting the 2016 and newer. The air filter part number is 17801-0P090 and the cabin filter is 87139-0E040.

 

Cabin filter a bit pricey.

 

I got a TYC 800208C and it fit perfectly.

 

Pic shown is a square shaped cabin air filter that fits 2015 and earlier. 2016 and later has a rectangular one.

Cabin air filter 2018 RX 350 …...Where is it? ….looked in back of glove box…not there. Help please!

 

I purchased an OEM engine airfilter, 17801-0P051, on amazon for $18.99 (free Prime shipping) for my 16' RX 350:

 

Did you drop the glove box all the way down? I haven't changed mine yet but that's how it is done on my other car. Disconnect the catch and the filter is housed behind there.
