I forgot to re-attach the lanyard and just pulled it back off without removing any of the screws. Honestly, I would suggest you pull off the glove box before loosening any screws.

Once all that is cleared-out, accessing the filter is easy. Just remember that the locking tab for the filter door is on the right side. It pops right off then you slide out the locating tab on the left.

You know, I never put those screws back in since I first pulled it off. Much easier when i change the filter or mess with anything back there.

Do this at your own risk, I'm not responsible if you break something using this easier modified directions.

First off. there are 7 screws total. Screw #6 is sort of a hidden screw.

Remove screw 1 -> 4. if you have a super long screw driver then remove 5 -> 7 also, if not then read next step.

Next pull off the glove box. Grab the 2 spots circled in red and pull upwards. This allows you VERY easy access to screws 5 -> 7 as well as a much easier time removing the panel. This step is OPTIONAL, but as i mentioned, it gives you easy access to screws 5 -> 7 and it also gives you a spot to grab panel to pull it off. To put the glove box back, just line up the hinge and pop it back in.

Next GENTLY pull off the panel starting from the RIGHT side first. You don't wanna damage that extension area on the right side by pulling too hard on the left. Insert finger where the arrows are and grab the bottom with your other hand and pull. Do the same on the other side.
Removing the glove box lanyard is optional (actually, mines popped off as i was figuring how to put the glove box back in after accidentally removing it) but it gives you more space to work with.
Remember, pull GENTLY, you shouldn't have to pull hard after removing the hidden screw, #6.

The rest you can follow caneman88's to install/replace the filter. I just have one thing that I found might be useful and that is to cut 4 slots on the bottom of the filter wall so that you can close the vent door without smashing the filter. You'll know what i mean when you take off the vent door. Just line up the slots with the 4 things on the door and make like a 1/4" -> 1/2" cut. See pic for approx locations, measure the actual location with the vent door.

Yes the arrow on the filter points down. Air is sucked from the top and down into the circular thing.

I assume you guys know how to reverse the directions to put everything back.

Rep points much appreciated if you found this addition helpful

*edit* Fixed broken image. Let me know if the links are broken and I'll upload it again.

Well… I know this is an ‘old thread’, but please don’t cut any slits / slots in your air filter. The white plastic ramps serve a purpose. They push the filter up against where it seals as you close the access flap.

How long do these filters usually last?

If they're similar to the one I have in my Toyota, it is recommended to replace them annually (possilby a bit earlier if your in a dusty climate).

I notice which one you put in but others have said to use a CAF1766
filter. Is there a better one than an other? Do they all fit the same,
or have less constricted air flow than another?

The correct filter and equivalents are:

STP: CAF1766
Purolator: C35479
WIX: 24883
Fram: CF10157

No need to notch the filter. The tapered posts on the door hold the filter up and in place away from the fan below. This is the one meant to go in there...

This is a Lexus/Toyota equivalent P/N Toyota 87139-32010 Apparently several Manuf. use the same air handling unit.

Fitment: Lexus ES330 v6 3.3l 2004-2005, RX400 Hybrid 2006-2009, Toyota Avalon V6 3.0L 2002-2004, Camry V6 2002-2005 & 4Cyl 2006, Highlander V6 3.3L 2004-2007 & Hybrid V6 2006-2007, Sienna V6 3.3L 2004-2006, Solara 2003-2006

The filter I got shown in my previous pic was pretty flimsy so I returned it. They didn't have any of the ones listed at the two Kragen's I went to.

I asked at a few places for the Fram CF10157 since it's a charcoal filter, but everywhere I looked it had to be ordered since it was a newer filter. So instead I went with the Fram CF10140 which is for the G35. It fits way better than the stock one which was a bit skinnier. This one is the same length and width, and leaves no gaps around the sides.

LOL! Those might work for some things - but 350Z's were famous for wonderful mildew smells from the air vents. Maybe the 370 will be a bit different?

Thanks for the DIY I would have never seen that screw #6

cab83_750 · 02-07-2010, 06:50 PM

I am not sure if I am paranoid but I could not figure out if CAF1792 would be the correct one because it might be too thick and too long.

In test fitting, there is a vent door that I believe will need to open and the filter may prevent it from swinging open. What I need to find out is if this door swings upwards or downwards.

I am out of time today so I apologize for leaving everyone hanging.

Btw thanks for the writeup.
