88 300E Cold Air Intake Project
so i have been researching air intake options for my 88 300E because A: I dont like the look of the stock air cleaner B:i want to attempt to improve my performance.
ive seen a few people pull this off but they placed the filter in an ugly position where there is little to no air flow my idea is to run my pipe over the valve cover and place the filter behind a custom heat shield near the passenger side head light. i was thinking of fabricating an air duct under the bumper to divert air to my filter.
i think this may work and im gonna give it my best shot. has anybody else attempted this?

This is something I am going to ATTEMPT, its just an EXPERIMENT on MY vehicle.
There are a lot of very nice, very helpful people on this site and I appreciate everyone who takes the time to answer my stupid questions. But don't act like I'm an idiot just because I wanna try something different.

Jesse, I'm toying around with the same idea. However, the important thing to note is that the w124 already comes stock with a cold-air-intake, so as noted above, improved performance is likely impossible.
All you can do is unrestrict it a bit by changing the airbox and make it a colder air intake (as I did) by insulating it with some high R-Factor insulation wrap. Another alternative is to use partitions to partition it off from the rest of the bay.
I'm going to work this summer on making a "track-kit" intake that will bypass the stock airbox and bolt straight to the throttle body. Reason? I want to hear the intake noise.
Go ahead & experiment

Wow calm down...didn't I just say that this will more than likely NOT IMPROVE MY PERFORMANCE.
This is something I am going to ATTEMPT, its just an EXPERIMENT on MY vehicle.

Suit yourself.
Those of us who have been on this board long enough have seen the millions of threads from new owners about increasing the power and all that. None of it works. You think AMG and everybody else bored out the engines because they wanted to go one step bigger or because there weren't significant gains by just changing the cam, the intake, and headers, using a high perfomance exhaust, like you'd do on a BMW or a Japanese car?
The M103 does NOT sound sexy. You're going to get more noise. It's not going to be sexy noise. If that is what you want, go for it.

I have a K&N in there, not for performance but cause its a cost-wise clean able filter, and yes it does sound a bit different. The engine vacuum isn't muffled as much. It's subtle enough, mostly on releasing the throttle fast, as it recoils..
If you want a colder engine bay, get a new fan clutch and hood vents....
As I keep repeating, fix the wear items! Your engine air intake will work its best if there are no vacuum leaks; all the rubber vacuum hoses, properly sealing valves, a good camshaft...
The M103 is different in not having variable cam timing, it screams as opposed to grumbles...

Way way way back when I used to be a mechanic, the shop manager and body shop manager raced a 300GE in rallies. This was in Africa.
That thing sounded marginally better than a tractor. Bone stock engine, modified intake and exhaust. The mods were more for water fording than power.

M104 sounds pretty hot though

Is the m103 really that different in sound?

I've also been looking at getting the 5.0L V8 from the 500E, but idk how much that would cost."
