Hey there Alon,

Thanks for all the replies. I am getting more and more addicted the more I come to this site. By the way... Killer looking Benz you have!
I really like your idea about the bumper scoops... If I understand your idea, we are thinking along the same lines. I can't tell from the pics of your car, but on mine (1990 124 3.0E) on the passenger front left, there is a removable plastic plate on the bumper which covers a tow hook. My original idea was to use that in combination with the existing hose for a dual intake system. However, I really think you're on to something with your idea, and it would really look good. I think I could remove the bumper and do the cutout myself on the drivers side. Then, add some sort of cool screen covering, and wow (Ala BMW M series). I think that is the avenue I will persue. I will keep you updated. I plan to use insulated flexible home air conditioning duct for my intake hose. The ducting is shiny on the exterior, which will reflect a good deal of the radiant heat from the engine. It is also fiber glass insulated which will keep out the convection heat. I think I will also keep the stock hose, for 3 intakes. As time (and money) permits, I will do this and post pics and results.

To answer your question about the cowl, you are precisely correct. You will notice the stock cowl curves around to the front of the radiator, with its opening to the rear, facing the auxillary fan. Not only is the cowl restrictive, but it is in competition with the aux and main fans for the same air. What I did is to cut the cowl where it begins to curve around, so that now, the opening faces directly forward in the direction of travel. I am not exagerating when I say I can feel the difference. I have a degree in Mechanical (Automotive) Engineering, so I feel qualified in my opinion that I am not just imagining the benefits. Thanks for the replies. My 1990 has 140K miles and counting. I have just begun efforts to restore it to its original glory. Next come the headlights. If you know where to get cheap euros, please let me know. Both of my headlights are broken so I have to aim them by hand.

Two final questions, for now. 1) how do you achieve senior member status, 2) My wife drives a 94 s420. Do you know of a factory service manual for it? Thanks!!

Best Regards,

Don Drake
