Since I had to replace these two filters, this weekend, I decided to document what I did for those who haven't done this before and want to save some money by doing it themselves.

So, take a look and tell me if anything is unclear; I'll do my best to make it better.

Here's the link:

hey that's awesome!!! thanks!

I have to change my cabin air filter soon, now i know how to get to it!!

I'm always amazed at how much trash finds its way into the cabin filter. 15,000 miles is really pushing it when it comes to how much dirt that filter can hold!

Dave, were those filters from NAPA labeled WIX?

I'm curious because NAPA told me by phone that they only carried the engine air filter by WIX but not the cabin filter in any brand.

Tom,

While there is no mention of "WIX", NAPA's cabin filter is considered to be within their "GOLD" line of parts. Here is the link to the fil4883 cabin filter:

...and the air filter:

I also picked up a K&N oil filter (735-5551):

Thanks, Dave.

I'm using NAPA's oil filters now, in part because I could find a spanner wrench to fit them. They told me that they were made by WIX but only have the NAPA Gold label. I'm guessing WIX also might supply the other filters you bought.

But I may still stock up from rock auto as they sell these filters very cheap--both air and cabin filters around $11-12 (prices seem to fluctuate). FYI we have two 400h's in our family.

Tom,

NAPA's website does list a less expensive version of either the air or cabin (I can't remember which), but I decided to go with their premium (Gold) line. They have a non-gold oil filter for many different vehicles, but from what I understand, that one is not made by WIX. I like the K&N because it has that very handy welded-on nut. I simply use an adjustable wrench to loosen the filter. Both the K&N and WIX filters have been given accolades by lab testers, so you really can't go wrond with either.

It's pretty easy too, to make your own re-usable cabin filter too, with a few sites like this one showing what's best to use for filter material & how to cut it to shape etc. For us, the $15 on line price has never broke the bank, so far ... so for us ... we do it the easy way and simply buy a couple at a time.

Dave, I agree with all you wrote. I used the K&N for my first "home" oil change and liked it's quality and the nut on the end but also thought it a bit pricy for an oil filter. I then bought the NAPA Gold (WIX) for $2.79 each for a quantity of 6. (I get a dealer discount at some auto supplies.)

Someone, the guys on the Porsche 968 site have made their own cabin air filters (0 or 2 depending on the year of the 968) out of home air conditioner filter material and come out fine. (The OEM filters are a substantial ripoff and there is only one aftermarket source which is a poor fit.)

Finally it raineth in Arizona after many months of dry. Wahoo.

Thanks, great instructions
