Anyone know what bumper this is? I'm thinking of doing something like that to my stock bumper to feed the engine bay some cold air.

 

I think arrows makes one like that. I think you can contact bulletproof to get it.

Hmm its not quite the same.

You really don't want any air to enter the engine bay without going through the radiator. If you were to add a vent for more cold air to reach the engine intake, that's fine, but any air that goes into the engine bay without going through the radiator actually reduces the amount of air flowing rhrough the radiator and ultimately increases engine temperature.

 

Fwiw, cold air is already entering - there is a plate that directs cold air up from the bumper and into the air box. This would just be a way to get air "straight in" vs up and in.

 

I think this is completely false, Thats like saying if you took your bumper off you would have higher engine bay temps...?

 

Unfortunately, it would only be false to say that you know what you're talking about.

I didn't say that engine BAY temps would increase from it. I said ENGINE TEMPS would increase. Unless you are hiding illegal immigrants under your hood, why do you care what the engine BAY temp is? Our engines are NOT air cooled. They are water cooled. Don't get too hung up on the temperature of the air inside the engine compartment. Just let the radiator do its job.

 

I have a full race turbo manifold and it gets really hot in the engine bay plus i don't have a stock airbox so there is nothing directing air inside ......anyone in socal have the custom vent stock hood cut out?? i wanna check that out and considering doing that mod.

 

its an ap1 front bumper that got all cut up, the ducts you see are made my chargespeed, i have the cf versions on my car and fitment is definitely spot on

 

I think you can get that bumper pretty cheap at extreme dimensions.

Im personally not a fan of the way it looks.
If you want a vent cut out in the bumper there are far better looking ones out there.

 

I'll say do a good job cutting it and save money!!
