Hi everyone! Like the title says, I have a 2013 Corolla LE, and I just want to share my mods with you guys. If you have any questions or advice, feel free to comment below! :thanks:

The first mod I did was install a K&N panel air filter, and so far so good. After that, I removed the ribs inside the airbox, sanded it down, and started to clean out the little particles



LED door strips



Plastidipped the front grill black(looks whitish in the photo) and added a rubber lip

I'm going to guess Home Depot

Those damn engineers at Toyota have no idea what they're doing...

Why put stupid ribs on the inside of the air box!?!

Hmm, maybe it helps to reduce turbulence and increase flow?

Naaaaah they're just dumb!! REMOVE THE RIBS I SAY!!

Haha, I'm joking, but joking aside, I'm serious... :)

I have no idea what those "ribs" are there for. Im just giving a point of view.

I remember on my first car, I got a drill and one of those attachments used to cut door knob holes and drilled a bunch of holes on the air box. Gave it that throaty intake sound under acceleration.

The sound of an aftermarket intake for SUPER cheap, since I already had the tools.

It was fun messing around with the car. I certainly appreciate what the OP is doing.

The ribs act as a air silencer and restricts airflow!

As for drilling holes, did you ever have any problems? I made a thread before about drilling holes but I was told it wasn't worth it :dunno:

Looking good so far. I'm also waiting for my rubber lip to arrive. But the shaved rib idea on the air box isn't a bad idea, I might do it myself even though if there are no noticeable gains. They're probably there to make it more quiet anyways like all the other useless little compartments that most stock air boxes have.

It's like a port and polish for the stock air box :rofl:

I think the lip I got is the same as the EZ lip. They look all the same on ebay so I got the one that looked the most decent and cheapest. I'm pretty sure it's just a garage door seal also. I'll probably add some screws or clips underneath along with the 3M tape.:lol:

I checked out my local home depot already here and they sell a different type of garage door seal now which can't be used as a lip.

I probably should have drilled on the lip instead of taping it :/ I wonder how long it will last for me :dunno:

There's always the option of buying it on the Home Depot website!

Wow, I just saw your post on drilling the holes. I see nothing has changed in 10 years. Same discussions going on...

Like they said. Some people argue less restrictive air flow is better, others argue colder air is better. That debate is older than air itself.

Either way, to me just for the sound, it's worth it!!

I would like a more throaty sound, but I actually just went back and read my post and they said to remove the snorkel completely? When I was removing the ribs, there were already 2 small holes on the bottom of the box. Hmm a sign to make them bigger?
 
#23 ·
If you drill the holes, removing the snorkel would be for weight reduction only but it won't hurt you if you leave it on. Besides if you ever decide to go back to stock it will be easier to just replace the box than to have to reinstall that snorkel.
 
#25 ·
What l mean is that if you drill the holes I would just leave the snorkel on. Even though it would serve no purpose, if you decide to go back to stock, all you would have to do is replace the box and hook the snorkel back up.
 
#26 ·
AH! Sorry for that misunderstanding. I'll probably take off the snorkel first and see how that goes. If the sound isn't as nice as I thought then I'll see what I can do with drilling holes!

little known fact, the MAIN bottleneck on the 1.8l toyota engine is the air filter itself. if you remove it completely it will increase performance AND you will have no need for the air box to be there as well. so if you remove the filter, you can also remove the air box.

:eek:

You can't be serious.

Thank you!

But for some reason, the stock rear is definitely higher than the stock front so how would the rear be lower now even though the springs are both a 1.5" drop? :headbang::help:
