Factory-louvered 124 fender

[linjam]

Pretty cool. Maybe we should modify our fenders to look the same. Looks cool and adds cooling:

Yes these came on the multivalve diesel W124s only. However note only the one side had the vents!! Therefore to me it looks a little strange to have one fender with big vents and the other side plain. The vents are also shaped such that you could not cut one out and weld into the opposite fender - it would require a panel specialist to press the appropriate vents into the left fender which would be $$$ to get done.

But yes it is a nice mod for air intake etc just that my OCD doesnt like having it one sided is all

I believe it was all diesels after about 1988. The 1990-up 124.128 (2.5 Turbo, OM602) had these as standard equipment. Diesels only had air intake on one side.

I've seen the vents welded into 036 fenders but that would be a crazy amount of work for almost no benefit.

I agree. Both sides or nothing.

No benefit? You sure? Our cars tend to run a bit warm, eh? A lot of engine in a small space. Anyway, even if no benefit, would look really cool.

That is correct. Diesels only. Air box with filter was on that side of the engine compartment and drew air directly from the finned area. If you look in the lower left corner you can see the boot between the air box and the fender.

Having seen engineers design cooling systems for large industrial engines that had sound attenuating enclosures over them, I can tell you that simply cutting an opening in an enclosure doesn't mean it will help cooling. Some times it makes it worse.

The idea is cold-air intake, I believe, same as on the diesel application. Of course the 034/036 already have this, pulling air from around the headlights, and people have fabricated slotted wiper panels to increase the ram-air effect... with minimal improvement at sub-autobahn speeds.

Having the vented fenders open would just be pushing air into the engine compartment and be of questionable benefit. The airflow has to exit somewhere else, and could cause issues at high speeds. As Dan described above, engine compartment airflow is engineered, and messing with it can sometimes backfire.

 

[skikrazey]

As GSXR & Dan have stated airflow is engineered, wind tunnel time etc. The air coming in has to go out, our cars have the under engine cover that channels air flow, etc. Not worth the time and money to risk messing things up. You could have an airbrush artist paint louvers on both sides for the aesthetic affect.

Exactly this! Not worth the effort (although my hoard may or may not include a vented 124 fender and cold air Intake duct) Both sides or nothing. I also donated a 124 vented fender to a local guy building a turbo OM606 w201.

Ok. I have been appropriately chastised on the air flow idea.

I still think they look nice. Could simply cut louvers into both fenders for looks and cover somehow from the inside to prevent air issues. Better than painting on louvers, I think. Anyway, fun to think about.

[gsxr]

I do like the appearance. And if they were made into a cold-air intake, that would be relatively safe!

 

[skikrazey]

linjam, responses were not meant to chastise you, just friendly advice from fellow enthusiasts.

I, too, like the appearance of the louvers, and as GSXR said if they could be made to work, there would be safe.
That being said, finding the room for the ducting would be a challenge as real estate under the hood of the .036/.034 is at a premium to say the least!

They are very cool looking on a "pedestrian" W124......of course I am alittle biased b/c there's one on my '92 300D. It's kinda of a subtle diesel bling...... if a diesel can have bling?? Haha.

I did just remove a vented fender from a '91 300D at the local PNP just like this one and in pretty good shape. It is smoked silver. And oh yea I'd take $343 for it like the one shown above. Boy talk about a markup!!

Correct Dave all 1990 and up 300D 2.5L Turbo. 124.128. OM602 engine. Come on all you nondiesel guys, you don't know what you're missing!

And as GVZ likes to regularly remind us, the "chick factor" has to be considered. Having a diesel and a 500E is off the map for chicks! When they want to....or have to....drive your car, the coolness factor all comes home to them when they have to choose. The diesel = it may take me an hour more to get there?? The 500E = I may get 2 speeding tickets driving to wherever!!

I doubt this would work well as cold-air intake. The diameter is roughly as big as one of the M119s two intake tubes.
And adding a second "diesel-intake" on the drivers side would collide with the ABS-unit...

In USA, we had limited diesel options... AFAIK the vented fender appeared in 1988 but those were not imported to USA. We only had the 124.128 chassis starting in 1990 USA model year. (And the 124.131 as well, 1995 USA model year only, E300 non-turbo).

In Europe, I believe all turbodiesels had the vented fender after ~1988, and the DOHC (OM605/606) non-turbos had them as well when those were released around 1993-ish.

Appears to still be available new for under $300 in USA from discount dealers, not sure why anyone would pay more for a used one?

Yes, you are correct!
I believe the non-turbo, four-valve diesels got the vented fenders in the US as well.

Skikrazy, no, I did not take it that way. Was just being tongue-in-cheek.

The Norwegian Brabus 6.5 has dual vented fenders. The owner told he used a right side vent from a Turbodiesel, split and turned each slot to get a mirrored vent. He has also vented the bonnet and I think he used slots from a splitted right side vent for that as well. The headlight wiper panels are also vented. He did all this to reduce the high engine bay temp, and said it was a great improvement. The owner ran a bodyshop earlier and have done all the mods himself. The finish on this car is absolutely gorgeous - with 350.000 km milage!

I don't know him personally but AFAIK he still has the car and use it regularly every summer. He had it up for sale some years ago, but I think the asking price was scaring for the public, somewhere around 70-80 000 Euro.

He has a nice W124 grill, and his tatoo makes him pretty connected to his Brabus.

Yes it was the turbo diesels that had the side vent on one side.
I picked up a new 300TDT Kombi in Essen in 1988, & it had this side vent.
It was a great car which towed our race trailer at 100MPH everywhere!

Now that is precisely what I was thinking regarding the front fenders. Pretty cool look.

Very interesting to hear his report on the reduction in engine temp. I wonder how much of that was due to the fender vents vs the hood and headlight panel vents. I wonder also if he routed any airways from the fender vents to the intake or just let external air flow in to the general engine compartment from the vents.

Would be very interesting to know. Is there any way of finding out? Can he still be reached?

These slots are actually of use on diesel. A while ago I was doing a conical filter mod along with heat shield in my e300d and the slots were great to add good amount of fresh air to filter.

Maybe dual side will be good for similar mod on 500e etc.

A guy from japan did 500e widebody mod to his 250d and he added slots to one side.

If its about adding fresh air inside engine bay for temperature reasons, I think its better to add hood scoop then say fender vents.

 

[036]

Does anyone have pics from 036 prototype with vents??

 

[500AMM]

If i´m not wrong- 036 prototype had those vents...

Arkady, isn't that a typical "it should have/ I've seen one/ I've heard about/ it would be cool" rumor??

I've never seen any prototype from the W124 development with that vent. It was introduced on the Turbodiesels (not diesels w/o turbo) for colder and less restriction of the inlet air due to higher suction volume with turbo. The 036 power pack is adapted from the R129 introduced in 1989, and it was developed in parallell with the W140 as well, so I guess any need for a vent like that was well debated before they started on the prototypes. But if someone can prove me wrong I'll applaude that - it's always exciting to reveal unknown production facts.

That Brabus has no custom air ducts inside the engine bay from those additional vents.

So then the question is how much of the cooling benefit the owner received came from those vents vs the ones in the hood and headlight panels? Do we know his name or how to find him in Norway?

He lives an hour away from me and I can reach out to him at any time by phone. I have never seen him active on our MB club forum, maybe he is on Facebook, Twitter..., I don't know. I'm not sure he has put much science into those vents but common sense to improve air circulation and thus cool the engine bay - without destroying the cars appearance.
The most crucial situations giving peak temps in the engine bay are when the car stands on idle and in slo-mo traffic. When driving the engine bay is vented anyway.

Another thing - the intention with vented [headlight] wiper panels is to improve engine breathing [air cleaner intake], while fender and bonnet vents improves engine bay air circulation.

Well, if it helps, it helps! Would be interesting to hear more detail from him on that, Arnt, if it’s possible and not too much trouble.
