How to Mod your stock airbox to flow better
Everytime I post in a thread about modding my airbox, I always get PM's asking how.
So, I decided to create a seperate thread for this, so that it can be easily search for if someone needs it, assuming they actually search.
First pic, If your car has a baffle here, put your hand in through the top and grab it. Rip that **** off. It's an air silencer, and getting rid of it will enlarge the cold air intake opening.
Second pic. Take the airbox lid off, look at the underside. You'll see another baffle, and yet again, it's an air silencer, but a HUGE restriction in airflow. I'll explain why with picture #3. Drill out the plastic rivets, as you can see it the pic, and it comes right off.
Third Pic. It's my K@N filter. See how the dirt pattern on it is rather uniform across 90% of it? That's a good thing, as we are maximizing surface area and thus, airflow. If you have that baffle in the airbox lid that you are about to remove, Your filter is dirty only on the left side and practically brand new looking on the right side. Look at the pattern of dirt on your filter, because that is where all your air is being pulled in.
There is nothing but good things to come out of removing these baffles. They are there to silence the intake, but really, you won't notice the difference in intake noise unless you have the hood open.
Do yourself a 10 minute long favor and get rid of that ****. It really only takes 10 minutes, does nothing but good, has no drawbacks....why wouldn't you?

If anyone can get me a picture of the baffles intact, that'd be cool. I did this years ago and din't take pics, so it'd help other visualize what it is they are removing.
I might could be persuaded...

Just to add, as I have been planning to do it but haven't, get rid of the ribs inside the airbox. The airbox and lid are reinforced on the outside, the ribs on the inside are also used to silence the system.
If it isnt too cold this weekend, I'll have a go at it, and post pics. We are having a 150yr record breaking cold spell so, we'll see.

It was under my impression that you are putting holes in the air box so and that'd suck air in that is not coming from the snorkel.
Unless that's not what this mod does and its just increasing the overall flow, I thought it was increasing flow by adding another place for air to breathe into the air box.
Sorry if I seem stupid , I'm really not I just learn alot by seeing pictures and reading, not just one or the other.

You are not making holes.
Take the top of your stock airbox off and look whats on the underside of it.
I've already modded my airbox years ago, and I don't have before pics. These are AFTER pics. If you look at your stock parts, you'll see what I removed.
