Direct Air intake Kit - dieselkid - 04-04-2008
I'm working on an air intake kit like this with tig welded metal oil bypass chambers instead of cheap spraypainted glued pvc ones. What are you guys using to make your turbo breath. And what are you going to do to make the liberty turbo breath. I'll be selling these soon. Egr Kits available too.

I am using something similar with an oil separator off of an airplane. My intake was intended for a Honda. Be prepared for K&N filter haters.
Re: Direct Air intake Kit - ForcedInduction - 04-05-2008
That is also known as a Hot Air Intake kit and its actually a downgrade instead of an upgrade.
Your best bet is to stick with the stock air filter setup as long as you can. It is a true cold air intake, it flows well more air than the engine can consume, it has a built-in oil separator and it is a good design for our engines.
Re: Direct Air intake Kit - dieselkid - 04-05-2008
I'd have to disagree with you on that one. My mechanic is one of the most well known mercedes gurus in the Pennsylvania area. He owns his own mercedes repair shop. His dad is full blooded german and worked for Mercedes in Germany. The mercedes dealerships send him jobs that they can't figure out. All that to say that he knows what he's talking about. I've heard him say that the original intake system on the mercedes was a poor design and that the engine can't breath the way it needs to.
my two cents.

I believe he is wrong on that one. Having a smaller filter that does not filter as well and sticking it on the end of a tube in the engine bay so it takes in hot air from behind the radiator is not a better alternative to the minimal restriction the stock setup has.
If you want to reduce it's restriction, get rid of the metal cage the filter sits around and make a larger diameter snorkel tube.
Re: Direct Air intake Kit - GREASY_BEAST - 04-05-2008
Problems arise when you have to put things where the stock aircleaner resides. My solution was to use a GM 3.8 airbox, which is somewhat restrictive. I think I am going to put a great big K&N cone on, and make a sheetmetal shield to try to keep the heat out.. I was also thinking of cutting some thin slots in the hood to let cold air in directly into the filter. This, combined with heat shielding, should ensure adequate airflow at the coldest possible temperature...

Why not cut a hole in the inner fender and some louvers in the fender like the W124 has?
Re: Direct Air intake Kit - winmutt - 04-06-2008
bgkast Why not cut a hole in the inner fender and some louvers in the fender like the W124 has?There is already a hole there for the cali? intake. Maybe its a gasser. Whatever its there.
Re: Direct Air intake Kit - bgkast - 04-06-2008
The '85 cali cars draw air from the fender like the W124 turbos. AFAIK they were the only W123s that had this air filter setup.
Re: Direct Air intake Kit - ForcedInduction - 04-07-2008
The 85 Kalifornia filter setup is a great alternative. Both federal and Kali W123s have the fender hole, the SD takes air from the normal front scoop location.
Re: Direct Air intake Kit - SteveM - 04-07-2008
Check a W201 2.5 Turbo or a W124 300D 2.5 Turbo. Both of these cars have "gills" on the passenger's side fender for fresh air intake. There is a seal which presses against the outer fender and is ducted through the inner fender and into an airbox. Then there is another heat sheild between the airbox and the main engine compartment. The only component on the "hot" side of this heat shield is a 90 degree fitting which goes to the turbo inlet.
This seems to be the best design for getting fresh, cool air to the turbo. If you want to use a K&N style filter, you could fab a similar seal against the outer fender with the gills.

The air filter assemblies from the 86-87 300SDL and 87 300D are also great. They flow even more air than the 617 filter and the offer two different inlet and outlet options (SDL and D). I'm working on installing one of them right now.
RE: Direct Air intake Kit - Gurkha - 01-29-2009
The original air intake is your best and safest option. Please veer off K&N, speaking from personal experience.
RE: Direct Air intake Kit - ForcedInduction - 01-29-2009
I have a California TrapOx filter system on the way. Its a big filter, its a true cold air intake and its mostly bolt-in. The only down side is $50 every year or so for a filter.
RE: Direct Air intake Kit - winmutt - 01-29-2009
If it makes you feel better the Motoroam's filter is $200. I will be washing it out and using as is

The a/c dryer hole is conveniently sized for the plumbing of that intake's inlet to drop down behind the front air dam with zero reduction in ID... unfortunately, you need a 90*

hippy.
How big is it? The filter.

Thats exactly the inlet I'll be using. In fact the rubber grommet used on the fender inlet of the 1987 300D is exactly the perfect size for that hole and the intake accordion tube.
RE: Direct Air intake Kit - winmutt - 01-30-2009
Why not make shark gills like on the 124. That shit is hawt!
RE: Direct Air intake Kit - ForcedInduction - 01-30-2009
I'm seriously thinking about it. I have some very nice vent grilles from a Corvair that would be perfect for the job.
RE: Direct Air intake Kit - bgkast - 01-30-2009
Do it, that would look great!
