Has anyone bought these?

Rumor has it they're made from Home Depot mixing bins. I contacted one person who bought them and they reported the bins, er, scoops ripped upon installation and instructions were worthless. |

Make them yourself if you really want them. Also, search the word Scoop or scoops and you'll find a multi-page thread on them. Some indicate some airflow increase. Had some for a bit, looked like my van had ears that stuck out too far. No difference noticed in the drive or power. A funny looking placebo if you ask me.

seeing as how those vents are more for heat exhaust, than air intake...
i dont see the point...

Ahhh, no, fresh air flows down the pillars. Considerable low pressure zone below and behind the van when moving, so heat leaves out the rear of the vehicle. Also the air intake draws air from there so the intaken air is above the dusty level near the road; makes your A/F last a lot longer.
Adding scoops would increase the flow down the pillars but it is already considerable. Oil coolers and intercoolers work really well when positioned in this airflow.

I messed around with them to see if they pushed more air down the D-pillar. I used a manometer to check before and after air pressure across my air to oil oil cooler that is mounted at the bottom of my passenger side d-pillar. The scoop made a notable difference, almost twice as much air pressure across the oil cooler under all conditions. Its all documented in one of the "scoops" threads.

As tencent said, air most certainly goes down the D-pillar when the vehicle is moving at anything more than walking speed.
Bottom line, if you have an intercooler or an oil cooler at the bottom of the D-pillar a scoop could be of use to you, if you have a stock van scoops are a waste of time and money.

I have my intercooler at the base of the passenger side D-pillar. Perhaps there was some benefit, but it wasn't anything I was able to notice. I remember reading the thread and saw Jack's manometer clips (which prompted me to try it in the first place), but I didn't notice any appreciable performance difference. Vanity ultimately won out and I am now scoop-less.
Now, if there were something other than plastic tubs for scoops I might be convinced to give'er another go, but it's gotta look pretty!

I think you would have seen lower IAT temps in Vagcom (assuming you have an E-TDI) with the scoop, but that doesn't make much difference in power, but does help keep the EGTs down a little.

Andrew--I've been thinking the same thing. Forming a scoop like this would not be the hard part--fastening it to the van elegantly, now thats another question. But, I have toyed with the idea of a flat piece of sheet metal applied (somehow) over the rear half of the outside edges of the indent that forms the scoop into the d-pillar.
Try it! Place a piece of sheet metal over the the trailing 1/2 to 2/3 of the scoop area directly onto the body work. You'll see the shape of bodywork would project the edge of the sheet metal into the airstream going past the scoop. Getting a nice fitment would be the biggest challenge, that is of course if form is as important as function.

I have an oil cooler on passenger side and an intercooler on the drivers side. Seems like it could be of benefit. Those look like the real deal they arent home depot bins.

Thanks for clearing that up ten.

.. do vans benefit from any ram air intake systems? or cold.

yeah, I bought them too a while ago, I have them around but haven't tried them on the van yet, maybe I'll never do,
Not a direct fit, I think they look better in a picture than in my van. |

| i have a pair of the above scoops what are a definate improvement in air flow for the porsche engine, but a speeds they flex and go out of shape so i replaced them with the more rigid carbon fibre ones what are loads easier to fit |
