is there a service interval for the secondary air filter on the stock 1grfe v6 airbox

Just curious, what is the point of the secondary air filter on the stock airbox on a 1gr-fe v6 engine?? And does it have a service interval for when it has to get replaced?? Because im sure after a while it does get dirty, and why is there even a secondary air filter?? It seems kinda pointless if u maintain you regular air filter and/or have a reusable air filter. Any feedback on this is much appreciated

 

Please forgive me for being a little crude but I guess it's akin to wearing a pad with a tampon.

 

Oh my. I can't believe I just typed that. I must be hanging out with the guys a little too much. Shame on me. I better go hang out at the "Proper etiquette" forums...

 

I would think there is no interval since it's basically in there permanently (Unless you're like me and went with the crowd awhile back and removed it for no reason. Aaahhh peer pressure... ).

 

If the pad was an active carbon odor filter.

Hey now there's an idea.

 

Lol,, and its all good lol XP! And that is quite an interesting analogy, thanks you btw xD

 

Oh wow, its a charcoal filter?? Damn I had absolutely no idea, and I didnt know it was for fuel vapor absorbtion, very intetersting and great info!! Thank you!

 

so it really does act like a tampon.... interesting.

 

Lol! Well dont feel bad lol, if I didn't ask about it, I was also gonna take it out too lol

 

I would say if you replace it every ten to fifteen million miles, it will probably be fine.

 

What'd I tellya? I swear. Nobody ever listens to the girl.

 

Feisty today aren't we..... A side of BT we have to tap into a little more...
Hehehehe
