The Air Intake Thread

This thread is for your air intake mods and general discussion.

I'll start with my first mod. On the left is the charcoal / carbon filter from an older car. On the right is the filter from a newer car. As you can see over time it gets clogged up pretty badly.



Good idea to have this unserviceable filter removed from the air intake box? Absolutely!

Did this as well when I installed the TRD filter.

It's just a panel air filter replacement like a K&N but I like it. Makes the throttle a bit more responsive, the car feels slighly peppier, and there is some added engine / cabin noise (I have the 6spd so this is more than welcome as before I could barely hear the engine). I prefer to hear the engine than to have to look at the tach to figure RPM.

Here is a diagram of the stock intake. #8 is the inlet tube. That design can't be good for flow.

Awesome picture! I was wondering what that snorkel dipped down into... It looks like you have to remove the headlight to get to that U-Joint though. Do you have access to a tech manual that would show how to remove the headlight? I would like to remove that U-Joint completely as it all just kind of snaps together.

I had actually ordered a Corolla HPS shortram intake, but canceled the order after I got the car and saw the design of the stock airbox. The stock airbox actually draws cold air from the front of the car. Every shortram intake I have seen for the Corolla's is on back order, but more importantly the cone filter is drawing air from right behind the intake manifold much closer to the header / backside of the engine. There would be almost no performance gain what so ever. The cold air intakes I have seen from the Corolla go into the fender well through a hole that doesn't look like it would line up on our cars.

Is anyone here planning to get a short ram or cold air intake?

Having done both in the past, a short ram is what i'll be most interested in. If you have a manual iM it'll make driving one even more enjoyable.

10mm deep socket and an extension should do it... Number 8 should def be out for a nice deep sound

Just wanted to make sure, do I remove the charcoal / carbon filter? If so how do I do it, it looks like it is stuck in there?

Thank you
