In the center hole in my front bumper cover (hole that feeds air to radiator) there are two black plastic walls making the opening smaller. It seems like I hardly ever see them on other FD's.

Is there an advantage to having these? Should I remove them so that more air may pass through?

If I should remove them, is they're an easy way? They seem to be permanently attached to the bumper. Should I just hack them off?

Thanks.

 

i have never paid attention to that. but it seems that if you took them off it would be better... better air flow.

 

it's for non foglight cars

 

My FD has those, and I had the oem foglights still.

I don't have the oem foglights anymore though.

 

I have a feeling that in a stock setup it probably won't improve airflow to the radiator / intercooler, simply because there would be no reason to have them there, with or without foglights, if they did.

My guess is that the smaller opening versus the larger exist at the base of the hood and under the engine creates a low pressure area in front of the car, drawing more air in and reducing turbulance. It might also be there for purposes of ducting...

Just some throughts.

 

no you got it all wrong, those are there to make the air from the outside be forced through the radiator. think about it, if there is a big opening, the air will flow through the sides but with those on, it forced all of the air to go through the ac condensor, then the radiator and then the intercooler on a stock setup.

knowing all that, i still took mine off. it just looks better and there is not that big of a difference because the only time you will ever overheat is in traffic when you are stopped. if anyone wants those for a MB color car, i have a set in good condition.....

 

So how do I take them off?

 

im really confused, i dunno if my MB has this or not lol

 

dremel tool and/or reciprocating saw

 

take them off and put on airsheilds

 

Ack! There is NO NEED for any exotic removal methods!
There are two T-shaped pins in the bumper that the little plastic things just slip over, they have corresponding T-shaped slots.

I have pics if you want.

Really, these just slip on and off....easy!

 

 

i was under the car day before yesterday looking at these. can you get them off without taking off the front fascia?

 

Just slide them off from the top (where the T-shaped pins and slots are) and then lift out. Simplest thing to do. You don't have to remove anything, though if you take out the front row of screws that holds the spoiler to the undertray it will be easiest. Literally you can just grab the damned things and pull them off! I'm surprised these aren't highly stolen items, as easy as they come out.

 

who would want them

I am gonna rip mine off this weekend. I think the whole channeling air thing is a crock(but hey I am not an engineer). To truly route the air they would have to go all the way back to the edge of the condenser. I think they just block air flow (again I am not an engineer).

 

What about the blank on the passengers side...the one that is an oil cooler on the drivers side. Any problem/benefit with opening that up?

 

i keepin mine.. too much rocky around my area, bend my ac densor and side of the radiator.. the fin on all my open area of the oil cooler are bent

 

Damn, it seems like I have tried to just pull them off before. I guess I just have to pull harder!

Also, for those of us with "cold air" intakes (intakes that pull air from the gap next to the radiator), won't removing them provide a more direct air flow?

 

yes, it will
