My Z didn't even have a cabin filter
WTF!!!

Same here. It's an 09 thing.

Same here but the posts on this issue sure enabled me not only to purchase
The best filter but also install it easily. Thanks to all who posted!:hello:

Thanks for this thread.:tup:

Hi, this is a dumb question maybe. Trying to rationalize this. Without a cabin filter, where does that dirt, particles, bacteria, whatever it filters exactly go? The reason I ask is well I have an 09 and I am going to do this ASAP, I am sure the previous owner did not know about this. According to the maintenance schedule it is supposed to be change every 15,000 miles. I am at 56k miles. Where did that funk go? Thanks

Most of it blew out the vents, into the cabin. Some will be caught in the duct work.

Thanks, that's what I was pretty much thinking. I steam cleaned the entire cabin, seats, rugs, carpet, upholstery the whole pie inside a few days ago. Just put in the filter, while I was there I decided to clean as much as possible inside the filter compartment before dropping it in. Yes I am OCD:icon14: Thanks to the OP and everyone that has contributed to this thread, it was a breeze even in the dark, was too lazy to break out a drop lamp or head lamp. :tiphat:

The fan will usually be the worst dust collector. If it's pretty clean, the rest of the system should be OK.

Nice writeup. Did have one question that relates to the last step in your original post.

BSSM?

Its time to me to make this happen this weekend:stirthepot:

my Z arrive to the 30k miles :rolleyes:

370Z Cabin Air Filter
 

Doing some research on cabin air filters for the 370z, I discovered Fram's Fresh Breeze brand does not have an official offering for the 370z. I gave them a call and they said their computer shows it's in development for the 370z, but it's unknown if and when they may have on available on the market. They could not give me an existing product they recommended as nearly the correct dimensions.

Almost the only part listed on Amazon as fitting the 370z is the ATP RA-141 which comes in two flavors, one which is a normal paper filter (CF-246 @ $25.84), and a premium activated charcoal type for around $15.70 + tax and shipping, the dimension are 12.7 x 11.2 x 1.5 inches. Curiosly, the non-charcoal white paper type was about $10 more expensive. Another brand listed is a Beck Arnley 042-2206, 2.5 x 8.2 x 11.8 inches $27.13. I ordered the ATP charcoal type which should arrive tomorrow and will see how well it fits maybe this weekend.

It's difficult to say at this point if the activated carbon is really any good at eating diesel exhaust fumes or other nasty smells over the normal white paper type. But with these prices, the more elaborate charcoal type is much less epensive than their paper cousins.

Watching some varying youtube videos on the subject, it appears the luxury car's are the ones with the more elaborate designs. They often employ two or more filters in the system, usually a paper type in the front end, and a more elaborate and thick charcoal type past the fan for more ordor elimination.

I'm unable to find the dimensions of the Nissan OEM B7277-1EA0B filter part for comparison.

The Fram CF10157 mentioned in the first part of this thread has dimensions of 9.8 x 0.9 x 9 which seems quite different than the offering listed as officially compatible with the 370z.

Update 12/30: I disassembled the glove box which wasn't too difficult and discovered the OEM Nissan cabin filter in my 2014 370z already appears to have activated carbon in the media. Nissan apparently changed their part some time ago and included carbon in the newer part number. The ATP I purchased from Amazon looks nearly identical to the OEM. The main reason to purchase an ATP may simply be the price, but it's not likely their is much difference in performance between the two. I can't say I notice any difference with the ATP over the OEM Nissan in odor control as some odors can still enter the cabin. For example, driving through an neighborhood where someone is operating their fireplace, and/or diesel fumes from a truck ahead of you. The OEM filter had a few spiders in the media and some dirt, but was in good shape (only 2,200 miles on the car).

I just removed the cabin air filter to check the dimensions. A few people on this thread have reported that they have used either the Fram CF10157 or the CF10140, and that they both fit. I am confused because their dimensions are different (significantly, in the case of the CF10140) from the OEM filter based on the info I found at framcatalog.com. Do these Fram filters actually fit properly?

Nissan OEM (27277 1EA0B): 7.875" W X 8.5" L X .75" H

Fram CF10157: 8.59" W X 8.87" L X .79" H

Fram CF10140: 7.88" W X 10.72" L X 1.18" H

Also, as Z Ninja pointed out, the OEM filter in the 2014 models has charcoal embedded in it; it is not white. Do the 2010-2012 models have white filters?

the one i posted is the one that's in my Z. no issues with fitment on my 2009.

Like i said and i post in the pics... I use the STP and the fitment its perfect... an the answer of the white filter on the 09-13 is yes... my Z is from 2013 and have a white filter ;)
