Car 1984 300sd 126/617.
Hey guys,I have a question,I did search but I didn't found anything for a answer,anyway,did anyone eliminate the air cleaner box on this cars and replace it whit nice cold air kit with K&N filter?
Is this passable on this cars or not?

do not use a k&n


i know your profecient with the gassers (hence the nice stang).. but a diesel sucks in all the air it needs plus more from the turbo charger.. plus the intake already takes air from above the headlights and is pretty cool.

the K&N really doesnt filter that well.. it lets more particles in than the factory filter.


forcedinduction has modified his intake to use an airbox from a buick grand national to suck in colder air.. but note.. completely experimental. but he is using a factory air filter

I replaced the air filter in my 300D with a K&N but it's in the stock air filter housing. There have been reports that K&N air filters don't trap dirt very well and let larger amounts of dust into your engine. Independent testing from the Air Research Institue has proven these rumors to be false, but ONLY if you oil your filter very well. Lack of filter oil was the reason given for questionable performance oil bath air filters like K&N. Also cleaning and re-oiling much more often was recommended. We have severe dust storms here in Arizona and I'm satisfied my K&N is doing it's job, but I clean and re-lube at every oil change. 50,000 miles between cleaning and re-oiling in my opinion isn't very realistic. A cold air tube with an aftermarket filter won't jive with certain emission control requirements in various parts of the country, like here in Phoenix, for instance. But a Oil bath air filter placed into the factory housing passes just fine. i can't get a straight answer as to their reasoning!

Diesels run best at full throttle and even better at higher temperatures, for instance, its easier to start when its warm out, than when its cold. Its probably wont do much if installed

I've yet to see a K&N "cold air kit." The kits I see use a cone filter behind the radiator, and ensure that your intake air is warmer than stock.

Isn't there a hose from the grille to the air cleaner on your car now?

yes.. its easier to start when warm but the air coming into the intake when cold is less dense than warm air thus allowing more to be crammed into the cylinders.

reason for intercooling

why was i thinking grand national.. why... oh well.. its off of some GM pos anyways

At least it was not off some ford pos.

Cold air kits on this cars are pointless, the factory already installed one. They provide no more power, make the engine a bit louder thats all.

I have yet to see two back to back 0-60 runs measured with say a G Tech Pro that shows a cone filter set up improves anything.

Actualy quite the opposite, I think unless your filter is really clogged the turbo will suck in all the air it needs and 0-60 times will not change.

K&N filters are also pointless on any MB, the factory intakes are not restrictive at all. On the newer ones with MAF sensors the oil from the K&N will often cause them to fail.

AMG is able to build 500+hp NA V8's and they don't use K&N's.

I agree that filters have improved dramatically in the last few years, but K&N's will last longer and save you money since they can be re-used. they are not for every vehicle. I use one because Arizona's dust storms have fine dust that a paper filter will NOT stop. Re-oil at every other oil change and you should be fine. Desert dust/sand will turn into industrial diamonds in a disel engine. A multiple layer setup would be best.

A K&N will let even more dust past no matter how much it's oiled, unless it's oil improperly and dripping. The K&N has visible holes in the filter media that you can pass multiple hairs through at the same time.....

Keep it stock, sounds good to me.........
Thanks guys.

I've never seen this unless someone has taken an air hose to blow it out between cleanings! Every filter I purchase will stand up to the light bulb test, hold a very bright light bulb up to the filter and look for pinpoints of white light. Also, I said a multiple layered approach is best. Wrap a foam band oiled well around the K&N and put a layer of magic lube on both sides where it meets the filter housing. Arizona's dust storms have 30% or more of particles smaller than 4 to 5 microns! You can also get oil bath filters with several layers of filter media stacked one on the other. I've never had a paper filter hold up to what dust storms do around here! fine dust collecting on the inside of the air cleaner where oil collects and catches the dust is a dead giveaway! I cured this problem with oil bath air filters.
