Dynamic air scoops..."snake oil" or practical?

Hi y'all from toasty Texas:

An advertiser on Ebay is selling "aFe Magnum Force" air scoops that mount behind the grill. They are supposed to direct more efficient air flow to the air box thus increasing horsepower and fuel economy. Where have we heard that before? Anyway, do you have any opinion regarding air scoops?

I know little of such matters, but I suspect the flow most affected is that of cash out of your wallet and into the seller's pocket.

Air scoops, in the age of very controlled engine air flow, are the last bastion of shadetree entrepreneurship!

Pay no attention to that anonymous Ebay fellow. What you want are Kaiser Kahuna Performance Scoops.

These may soon be offered by Dinan, but you can acquire them now at a low, low introductory price!!

Please PM for cost info and Caymans bank routing spec. You won't be sorry - these scoops will supercharge your ride!!!



N54 may experience larger gains than N55.

I purchased them originally for aesthetics, but after installation I did noticed that I gained a full MPG in the efficiency department.

For the record, I purchased mine through Cyba over on e90post.com. $40 shipped

They won't give you any kind of performance boost. I had it, and it's easy to install (screws under the hood). If you get them in a nice color it will give a cool asthetic. Other then that, it's possibly it may help funnel air better towards your engine cooling it off just a little bit more - not enough for you to notice anything. If it makes you feel better then go for it

Snake oil on a turbo, minimal difference on an NA at speeds above ~70mph (6th "seems" to pull minimally better in my M3 based on my butt dyno)
