Air Filter Pre Filter

What is the purpose of the prefilter before the air filter? I drive very dusty roads often, yet my air filters are clean. How do you know if the prefilter is clogged?

 

It’s not a pre filter. It’s a charcoal filter that filters emissions that back track from the intake when the vehicle is shut off. The charcoal filter isn’t in the intake path. Rip that sucker out.

 

Thank you.

 

Why?

 

Good question. I am not touching mine until I figure out is Toyota will recall the 2024.

 

I’m not forcing you too. You might see some gain and some turbo noise.

 

They won’t. My 24 build date is way past. If anything we’ll see short blocks and not full engine replacement.

 

So is the Tundra engine in the Sequoia?

 

Yes it’s a hybrid. Tundra can have either.
