Anybody know what the oem part number is for the intake air filter? Also, who the manufacturer is? I know MAHLE makes the oil filter and just stamps "TOYOTA" on it, but have no idea who makes the air filter that they install at the factory. I would rather use OEM parts but not pay stealership prices if I don't have to.

 

Didn't get an answer so I just forked over the ~$26 at the stealership to get a new one. Made by Denso.

The one from the factory says "TOYOTA 17801-31120 DENSO MADE IN JAPAN >PET< HSA9"

The replacement the dealer gave me says "TOYOTA 17801-AD010 DENSO MADE IN USA >PET< CTNc"

I'm not sure what the second half of the part number means, but it fit so I'm going to assume it was a serial number or something of the sort.

 

In the Toyota world, Japan made P.N.'s are only numbers, that is why you have a Denso Japan P.N.


For North America made P.N.'s, the first portion of the P.N. is the same as the Japanese one, but on the second half includes a letter(s) to differentiate where was made, that is the reason of the second portion difference.


I work for Toyota, that is why I know. But your part is the correct one.

 

Excellent information. Thank you!

 

Just grabbed one myself from Amazon for $16.

 

That's what I plan on doing in the future, I just couldn't confirm the part number and didn't want to mess with taking the old one out until I had a new one to put in.

 

Sorry I didn't message back soon enough lol. It's tough to get real answers on this forum now a days.

 

It's alright. A lot of older car forums are starting to die off. Honda-tech is pretty much dead these days, and it used to be buzzing with active users (although if you honestly have a problem you can't find the answer to already on Honda-tech, you need to learn how to search better).
