Hello people,

just got the Legacy a major service, changed lots of fluids but I havent had the air filter changed. The car has had the same Subaru air filter since I bought the car, and it may have been the same all its life (looks reasonably clean). The car had just hit 80,000km. How often do you change the air filter? Also, which wrx one will fit the bh, the GD one?

Thanks

Will

Not sure which ones fit which but I changed mine on Friday night just gone and that was about 12 months after the last change (~25,000kms).

Old one wasn't too dirty but it's good to keep it all clean.

Matt does his every 5000kms

Did you just go with the Subaru item?

[aekOne]

Yeah I do mine every couple of services or so. In between i just get the blower on it and get as much of the dirt, dust and crap out as I can

I thought most Subaru's share the same filter (liberty bc/bf bg/bg be/bh impreza gc/gf gd/gg forester sf sg)?

Got a Ryco one.

They're all the same AFAIK?

Just don't get one that you need to oil.. AFM will go spazzo!

[alexGT]

every 5000km, ryco replacements are $7 for gen2/gd wrx/lots of other subaru (A360) as it is the same as most commodores

[Matt]

Ayyy another frequent changer!!

[bigboyscottyb]

Ryco ones are the way to go, i stupuidly bought a k&n one as they were listed on the website with their own part number (so hence i thought that they were special) then upon further investigation... Ryco ones are like $7.50... for that price Matt you hit the nail on the head

Just put it up to a light, if it doesn't shine through the element . Its f*cked.

[SUBARU]

Paulio... How have you been mate? What's news?

[Soop]

I've been good.

Hi guys. Can anyone confirm that my my02 b4 has an ej208 engine and uses a ryco a360 air filter?
I have a k&n panel but wondering if it's better to go back to stock.

[Tim.]

Yeah swapped mine last week. B4 has an A360.

[migoreng]

Thanks Tim. $12 at autobarn!

[Tim.]

Because commodore air filter.

[migoreng]

The k&n is drying outside while I'm driving around with the paper ryco filter.

I know the MRT site says no gains but anyone have more info about OEM filter vs k&n panel?

I know I have to be careful not to over oil it.

[Morgan]

Don't use the K&N.

It will coat your AF sensor in oil.

It's an air filter.

If it's clean, it will work.

[aekOne]

^ this

don't use an oil type filter

your oem paper filter is fine

[Adam]

My motor would have over 150000km on it now.

I haven't sucked in a piece of engine exploding dust yet with a paper filter

I think the stock airbox on the B4s account for 2% of the restrictions in the stock inlet. Leave it stock. Anything else is inviting problems, or reducing your flows.
