My AEM is a dry filter and doesnt need to be cleaned (which I find a bit bizarre); I tend to air blow it every 6 months just to give me piece of mind.

 

K&N on the other hand need to be oiled - not sure whether that applies to their entire range..

K&N are lifetime guarenteed, I know the one you have and it's covered by the warranty. They are a wet filter so need oil applied when indicated (can't remember how often).

But do they need cleaning somehow or just spraying with there oil & if so how often ???

Every 50K with K&N spray cleaner and then re-oil.

amazing isnt it considering that the stock toyota air filter needs to be changed every service.

Just give it a blast of compressed air before applying new oil, don't go putting it in the dishwasher Not sure what type the oil is, but it's only a few quid from K&N.

Long way to go before that needs sorting out

Just don't let K&N know you did that.

Not sure where you got that one from mate, the service schedule says to replace it every 30k miles or every 3 years, whichever is sooner.

[Homer]

Just don't let K&N know you did that.

 

Not good then?

[Miguel]

I'm not going to say anything if you don't.

Oh dear, I used to wash out bike K&N filters with carb cleaner, dry and re oil, lasted for ever, engines never popped either. I'll probably do the same with my AEM filter too but not adding oil

But your warranty didn't

the dishwasher is a great place to clean a K & N, when the wifes not looking of course , new K & N oil can be purchased from Halfords, comes with instructions

[TLicense]

I think the directions on the K&N cleaning kit tell you to use compressed air from the inside to the outiside to remove any loose debris, then spray with the cleaner, then using low pressure water from the inside wash the cleaner off and let it dry. Once dry apply the oil and again allow it do dry.

Job done.
