Question Air Shrouds for a 400EX? Really Work Or Hoax?

Can anyone tell me whether or not the aftermarket air shrouds that go under the front fenders on a 400EX really work or is it a farce? I'm sure you all know what I'm refering to and am sure some of you are running them. What are your thoughts and experiences with them? Any evidence that they do work? Are they really worth the $50-60 or is it a waste of money? I'm debating on whether or not to buy a set to keep my 400EX 's chill factor in check.

Actually they do aid in directing more air to the engine.

Yes they do help. I just bought a 4" spal fan to mount to the oil cooler for the same price.

Im looking to buy them as they actually do help out a good bit. i bet is you added a fan, larger oil tank, and the scoops you would have a helluva cool running 400ex

I run them on my 400ex even as we speak and even balls to the wall racing it never climbs over 200-225 as long as I am moving at a decent pace the motor stays nice and cool.

here is a pic of mine on there

For the 05 and above 400ex, air scoops are non-existent on Ebay. Do see plenty for 99-04. Would some customizing on the 99-04 make it fit on the newer version?

Any chance you could post a link to show the fan? Also where did you wire it in and how did you fab up the mounting? Got any pics?
