Modded factory air box

I removed my snorkel from the front of the box.   I had  GTP prior to this car and I modded that box with excellent results. I would like to create another opening in the box and run a tube/ piping down underneath to the front, or into the fender well.

Who has done this?

What did you do?

What were the results?

Would you do it again?

Thanks.

I thought the stock opening went straight to the grill, grabbing ambient temp air and even forcing it in a bit at speed?...can that be improved on?..just asking...is wheel well or fender air better than the air in front of the car?

How did you measure the "excellent" results of the mod to the gtp...

I've done it with a 3" hose/tube. Went down to the lower front grille.
I don't have pics. But I'll take some tomorrow.
I did not remove the factory snorkel.
IAT go to atmospheric temps faster and it recovers from heat soak quickly.

The hole in the SHO box is considerably larger than that of the inlet on the snorkel. As for the G T P, I swapped between a modded stock airbox and a fender well intake. My IAT dropped when I installed the port on the side of the airbox and ran it into the fender.

I added another intake to the stock airbox on my MKS and also left the original.  Due to the adaptive headlights, I think there is a little less room on the MKS than on a SHO.  I ran the tubing through a tight opening in the inner fender and down to the area beside the lower grill.  I cut an oval hole in the plastic insert as can be seen in the photo.

Thanks for the pics. What did you use for tubing?

I first attempted to use 3 inch tubing that I got from Autozone.  However, due to the contortions of getting it through the fender well, it basically crushed down to a little over 2 inches.  Rather than that, I settled on some 2.5 inch vaccuum cleaner hose.  It is very tough and flexible.  The inlet into the airbox is 3 inch PVC drain pipe that is glued into the airbox.  You can see the rubber reducer that I used to attach the vac hose to the PVC.  Again, I think the MKS is a bit tighter in this area due to the headlights that swivel when turning.  With the SHO, you might be able to use 3" all the way.

I tested this with a house fan positioned in front of the car and can definitely feel air flowing into the airbox.  Also, I am getting a lot more bugs into the filter than before.  Having said that, I cannot claim that it helps performance at all.

I did something similar on my Flex.
Better sound and keeps the IAT down closer to ambient.

I took off the snorkel last night and it definitely sounds healthier. With the snorkel I hear a definite suction sound with LMS tine. Without the snorkel, I don't hear that anymore. At speed its probably fine, in traffic im sure its worse.

Forgive me if I missed something here. But sounds like you are sucking in un-filtered air. As I recall from stock air box, air flows from top of box , then downward to turbo inlet. So unless you are installing another filter inline I would NOT perform this mod. Again, maybe I missed something somewhere. If so, I rescind my comments. If not, well........

after a bunch of driving, I can't seem to tell a butt dyno difference. Charge air temp is higher so in the summer it probably won't be good. Put it back to stock.

Im not sure why yo think you would be able to feel a difference.

There is a type of Zen some of us feel with mods that maybe don't add power but add to the feeling of the car, no change in Zen with removing the snorkel (IMO).
