Modded factory air box

[Expygator]

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...

Want more power for the sho?...grab a tune

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.

^  But its cool and thats all that matters

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……..

Ariflow is reverse, bottom up through the filter.

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).

 

[Brucelinc]

The factory snorkle picks up cooler air from the grill area and feeds it into the airbox.  Maybe I have lost my zen but I don't see how removing the snorkle could do anything beneficial.  I am surprised that it even changed the sound.

For me I like the concept in an attempt to catch more air as it seems the snorkel is too small especially when compared to that of the F150.

Removing the snorkel does give you almost twice the area of the opening of what you have with the snorkel installed. Unfortunately seems like it gets negated since its getting a lot of its air from behind the radiator which is hot. Further modification might make it better than stock but then you have to chop up your stock air box.

Correct me if I am wrong. I don't think there has been any evidence that the stock box can't flow enough cool air to a bolted and tuned car. From what I have gathered, aftermarket intakes have not shown any significant improvement over the stock box with a K&N or a dry flow filter installed. Not saying there is not room for improvement, but if the engine in its current configuration "whatever that is with your parts" can't pull more air and that is not due to a restriction in the intake then what is the point? Cooler air is another story of course, but taking the snorkel off its not going in the right direction.

Right now the snorkel opening area is actually larger than that of the 3 inch intake pipe that connects to the top of the air box so I have to agree that there isn't much point. I think I saw bpd making some type of custom piping which has individual pipes coming from the turbos vs the Y that is there now.
