I dont have it on and was wondering if there is any negatives to not having it. It doesnt seem from my experience so far that it affects the driveabilty at all. I was a little worried about the engine and everything getting covered in water and road grime but it seems as though it stays dry without it. I was also worried about sucking water into the intake(HKS) but that doesnt seem to be a problem either. Anyone else have any experience???

 

mine got ripped off from all the chunks of snow in the road all winter, ive been running witout one for a few months and there are no problems i have ran into yet, but there could be something that i dont know about that somebody could fill me in on

 

I am running Without it either Not for a very long time but i am for now Dont feel like putting 154623477 Screws back on i will after i get my car dynoed later on this upcoming week

And it dosnt seem to hurt anything at all but just to be safe i will put it back on.

 

ran around with mine off for about 2 months cause i orderd so many parts in those 2 months didnt want to take it off and on like 40 times... never had an issue it snowed rained etc....

 

I had mine off after I put on my IC pipes, and left it off for a while and it was totally fine through the rain, but put it back on before it snowed here...

 

Probably doesn't make any difference in real world driving, day to day, but it does have those deflectors to channel air towards the brakes. How usefull they are in actuality, is anyones guess.

Anyone not planning on reusing theirs and want to sell it?

 

yah i would be interested in buying one if someone wanted to sell it

 

i'll sell my.i can't find the small center piece,but have the main big piece,and two side pieces.pm me up if any of you's wants it

 

People People People. I took mine of also, when I was putting my intercooler piping. BIG MISTAKE! I drove thru some gravel. Nothing major- thats what I thought some of the gravel got into the pulley system and ripped a piece of the belt off. Any way put it back on went to the dealer. They replaced belt and tensioner free of charge. I also think they said its good for undercar aerodynamics.

 

I would think its good for something. It seems like it protects from water splashing up on the motor and over time its got to be keeping a lot of road grime off the engine block. Also wouldnt it help help the air turbulance going underneath the car ?

 

had mine off 2 months now.. im lazy.. but ill have alot of cleaning to do this spring.. my work car died so know i drive the evo... it sucks only being 4 inchs off the ground when it snows.. oh well..

 

Airflow control.
I would expect the car to run hotter in the warm weather because it should be helping to control the airflow across the radiator and IC. Many car have some type of air dam undertray for just this reason. Thus the reason it runs all the way forward to the front fascia. Also, the oil cooler should suffer since the air that enters up front can exit below and not flow across the cooler.

 

very true.. but for everyday driving its fine.. on of the main reasons mitsu put it there was aerodynamics...
