MODS
I modified my grill so that air will force into the intake. Its not like i just put a huge funnel on the grill, nothing crazy. I cut the supposed "holes" in the diamond grill so that air fill flow through the grill and into the intake tubes.



Nothing major, I did this on both sides, I still want to cut out the other 2 diamonds.
Thanks!

I just got performance tuning from powerchip. I'm in the middle of doing a wright up about it but the thread has already been created.
Thanks for the suggestions. any others?
I am not trying to attack or insult you. That statement has ignorance. Everything has room for improvement.
As for the intake ports on the R class, they seem better than many cars as they are directly facing forward with no turns and minimial angles. Most cars turn up 90 degrees to avoid water ingestion. This is the safety/reliability compromise. The R class compormise for water ingestion seems to be the blocked off grill. So yes, open that up to get more air flow.
As to the ones who say MB has already done it all. Yes, possibly. For the volume of air the 3.5 L engine requires, the dual intake probably suffices. So why open the grill? If you want to get the abolute max air flow at the lowest possible temp. Will it make much difference? Not likely on the factory tune. But if you can increase the engine efficiency through other modes, it can help.
I have K&N filters because I like the ability to keep the fliters at their cleanest. If there is increased airflow too - well thats another bennie. Never had dirt problems in the TB in every car I have put a K&N in. You just have to oil it properly.

Agree to this, do not over oil the K & N filter after cleaning because it will damage or contaminate the mass air sensor.
The best way is discard the old K & N filter and replace with the new one, If one does not want to clean the filter and re-oil.

good point!!

One thing they did to prevent taking in water is to have the air filters on the top, so they suck up, and the water will settle at the bottom.

I have made driveway mods with bolt on parts on my Corvette that have netted 60 hp at the rear wheels.
