Re: [MBZ] Increasing air flow in Diesel
I agree with Allan, that diesels do generally run "lean"; with a oversupply of air. However, there is some advantage to "cold" air intakes, inputting cooler air than the heated air that is present from behind the radiator. Some claims are for a small density increase and some fuel efficiency and horsepower gains. I have also read of intake vents that are positioned at the windshield/hood interface to take advantage of the higher pressure differential that occurs there. Supposedly, cooler air as well as a small pressure increase is worth some mileage and horsepower gains. The other advantage is that by removing the high pressure air that the aerodynamics of the vehicle improves since the drag coefficient is now lower.

Re: [MBZ] Increasing air flow in Diesel
Friend with 06 Ford F250 Diesel has gotten hyped up about and has ordered parts to, supposedly, "increase" air flow in his Diesel and, supposedly, increase fuel mileage by 10 to 15 mpg. Parts include "Coolair" filter and larger exhaust system. Somebody, please remind me about airflow (trying to improve it) in a Diesel, lack of throttling, etc. I'm only aware of improving the air flow, and especially cooling the intake air charge, to gain more horsepower rather than to improve mileage. But I'm spoiled, and can have 25 MPG out of my Dodge any day I care to drive that slowly. (Unloaded.) -- Jim
Re: [MBZ] Increasing air flow in Diesel
Modern US diesels are under-rated for pickup use (so the frame doesn't bend up like a pretzel and the tranny lasts most of the warrenty), so it's very easy to get LOTS more hp from them (double in some cases). Just re-program the computer to deliver more fuel. Reduces the already pitiful milage that much more, though. K&N lives on -- won't do any more for you on a diesel than on a gasser. Peter
Re: [MBZ] Increasing air flow in Diesel
Those are fine for pickup trucks, bigger exhaust and cold air intake. Will give you a couple more miles per gallon. NO WAY it will give you 10-15 mpg more. No reason to do that in a mercedes diesel though. wilton strickland wrote: Friend with 06 Ford F250 Diesel has gotten hyped up about and has ordered parts to, supposedly, "increase" air flow in his Diesel and, supposedly, increase fuel mileage by 10 to 15 mpg.

Re: [MBZ] Increasing air flow in Diesel
I have heard that you CAN increase power and mileage in modern diesels, though I heard most of that with a computer update. But free-er flowing stuff is good for that too... But, uh... 10-15 mpg?? Like near doubling it??? Now THAT sounds like an awfully big crock...
