Swiss Chees Airbox Mod - Did I just help or hurt?

He's an idiot. And why would you do that to a brand new car?

This

Since he's so good at tuning cars, and recommends this "mod", what does this do to your AFRs?

Moral of the story: don't listen to this guy again...

This

He graduated from UTI. Instant sign you shouldn't take his advice.

Don't knock UTI because some idiot told this kid to do something. I've had several friends go there and they're good at what they do and knowledgeable. Schooling is all what you make of it. Just because someone goes to Harvard doesn't make them smarter than most...

I have a lot of friends that have graduated uti and have a very good understanding of what there doing. Don't knock uti because some kid doesn't know what he's talking about. Anyone can talk like they know what there talking about.

This.

What I don't understand is, what was the point of destroying it with holes. You could have just completely removed that half of the box, and taped the filter to remaining half.

At least that way the ricetastic stupidity is reversable.

Actually, the "Swiss cheese mod" is pretty common on other makes. I remember it was pretty popular back when I lurked on the BMW E30 forums. Over there, it was as common and accepted as the intake silencer delete is for us.

All that being said, this is a totally different car, and I'm not in any way condoning doing this to your WRX, as it already has a sort of cold air intake from the factory, unlike the BMW, but this particular mod is not uncommon on other makes.

It was meant to be one of those just because you're "smart" doesn't mean you're smart metaphors...I think I failed though

i have the "American Cheese Mod." its holeless and flat. works decently up to around 400hp. and the snorkus delete, but i dont think the newer cars come with the intake silencers. didnt they stop that in 08+...?

STIs still have them,WRXs do not.

Yup, what Rage said, I was just illustrating my point that some modifications which are frowned upon in our circles are much more popular and/or beneficial in others.

Drilling the airbox to pieces in a brand new car isn't a good plan in any case though. The cars I saw this done in were pushing 20 years old (and none were Subarus)...

Fixed it for ya!

it definitely won't screw up your A/F, since it's before the MAF sensor.

It can't be too bad, since it won't let particles in, since it's before the filter.

It can't be good, since the filter is still a major bottleneck compared to the rest of that stream, and all the air that is let in is warmer than it could be (and it makes it so less air comes from where it's cool).

I concur. All you have effectively done is make it a Frankenstein short ram intake. Hot air = no bueno.

if you had removed the airbox you would have seen the 4" round area at the bottom that you could have used a single hole saw to cut out and thus drawn cold air from the fender well.

This would also defeat the snorkus "ram air" effect of getting cool air from between the hood and grill (since at speed it would just blow air right down and out of the airbox vs slightly pressurizing the airbox) .. but at least its cool air.

Any way you slice it (haha.. get it.. slice.. ) pulling in warmed air in the engine bay is counterproductive. Tape over the holes and save for a proper intake and tune if you wish to gain power that way.

That piece on the bottom of the airbox looks like it is designed to accept an intake hose. Is this airbox used on other models with an inlet at the bottom? Could that be adapted to this car?
