So I put a piece of screen from a screen door in my air box and it sound like my car is dying. Any tips to fix this? The cut isn't pretty and i didn't glue it to the filter. Also I am getting a K&N tomorrow, should I do the screen to this as well?

Remove the screen. It does nothing for the engine.

The window screen farce is all over the internet. Remember, if it's on the internet it must be true.

 

[Dragonsys]

umm, your air box already has an air straighter...
Please say you are a troll

 

[BowtieGuy]

I mean I could understand where someone could read a little too much into them on the internet and sort of believe it. But that someone would cut screen from a screen door and think that it would have any "air straightener" properties is pretty out there.

 

[obermd]

I actually saw that as a procedure on one of the crank sites.

For the factory air box, not necessary. For the Injen intake, big difference. Many people have installed this screen on their cars on factory intakes (K&N and Injen) and noticed a significant improvement in driveability and part throttle power smoothness. The reason is because, as poor of a filter as it is, it does filter the air a bit and smooth out the airflow so it isn't as turbulent. I can personally attest to the fact that it works, which is why I created a thread in the Powertrain section advising that people try it. Some noticed a slight, low single digit hp loss in the very top end as it will restrict some air, but many people said the benefit was more than worth it for how more driveable their high-powered 1.4T became.

Bottom line, it reduces turbulence, but isn't necessary on the stock intake. It was only intended to be a temporary relief until people found themselves a proper honeycomb air straightener designed for that purpose.

I don't need no stink'n air straightner................I got the TORNATO!!!

bahahahaha I love that thing its hilarious.

This is why I'm hesitant to recommend an aftermarket intake for these cars. Unless there are some serious mods necessitating more volume it generally gives little to no gains over a res delete air box with a drop in filter, and results in issues.

As far as air "straighteners"? In my opinion there is a better way. I feel a redesigned MAF sensor and or placement that provides better stream metering should be coupled to a CAI. Further more IF that much air is required perhaps a speed density approach should be explored.

It isn't a matter of velocity but a matter of turbulence, and that turbulence is a consequence of poor intake design. Even the factory intake has an air straigtener. In all their brilliance, none of the aftermarket intake makers have one on their intake.

And yes, there is little to no performance gain on an aftermarket intake.

Xtreme, any news on finding a company to make a short ram for us??

TRE was supposed to be helping us, then they fell off the grid. Kinda wondering if the guy I was working with got laid off, or if they gave up on the project. I told them if they didn't get back to me within a week, I'd find someone else to do it. That was 2 months ago. I'll call them tomorrow.

I put and intake on mine just so I can hear the spool ... some may call it childish but think about it like this why do people put exhaust on muscle cars the same reason I put an intake on mine

No, not a troll. I tried it because of your post in the power section. Meh, haven't noticed anything major. So should I get a honeycomb for my K&N filter drop in?

Your factory air box already has an air straighter build into the lid(look when you have it apart next time). Its mounted just in front of the MAF sensor.

Yup, put in my K&N and saw that. It has some pretty big holes. Wish it was a tad smaller to be more effective.

It doesn't need to be any more effective, it works perfect for the stock intake, as it is.

 

[XtremeRevolution]

For the stock intake, it really is perfect. No need to add anything else. The holes are bigger, but that's by design. That intake doesn't suffer from much turbulence.
