I got the idea from Project Car magazine. They did this and some kind of plywood splitter on one of their sentra SE-R's. Thought the idea was kind of cool, so I decided to try it out. Lowes sells aluminum strips like this for around $20, so it's really cheap... in case it rips off on a speed bump.

I'm kind of hoping it'll help with airflow into intercooler, and hopefully enough to my radiator and oil cooler to where I won't need to upgrade them. Hopefully...

I just had to do some more trimming to my new bumper, damm fmic blocks alot of air from coming in.

Is there a clear path on the bottom of your bumper for air to flow into the undertray or is it obstructed by the IC?

Nope. Completely blocked. I'm thinking of fabbing up some sort of low profile aluminum scoop (made into the factory underpan) to direct air into the radiator, but that might mess with the IC airflow then....

have you driven the car yet? I bet it will end up running hot like mine does, well alot warmer then I would like it to.

On my last bumper I cut the middle completly out and it was a night and day difference in the engine and inlet temps because now the undertray had a clear air path.

On my new bumper I tried not to cut it, instead put 2 slots in the bumper, but I drove the car for the first time today with this new bumper and the temps slowly rise, so instead of chopping the whole middle out I did it a little different, but it started to rain and I could not get a good picture of what I did.

Better than all the other "ghetto" lips we've seen. Most are terrible and held by tie wraps. Looks like some quality was finally used here.

Thanks!

As for airflow, I'm a little worried still. I'm still waiting for parts so I can finally start this thing up, but I just don't know if I'm going to get enough air to my radiator.

I'm trying to maintain as much stock look as possible, which is why I painted the IC flat black to try and hide it as much as I can. Hell, that's the whole reason why I went to a FMIC anyways, is so I didn't have to have the TII hood! The lip, I think, just looks good, and can be a functional piece on any car, which is why I went ahead and made it. Anyone got any ideas on how to get some airflow without cutting the bumper? I just can't stand the look.

How about my idea of making an aluminum undercar duct? Would that work?

the duct needs to direct air into the undertray.
I tried to get pics of my new set up, but they come out looking like a stock bumper. Im very happy with my new set up compared to my old one.

Maybe on a sunny day I can try to get a picture, but it photos like a stock bumper because my car is black, but it looks like some crazy add on spoiler thing in the opening.

I drove the car today and the car runs 10000% cooler and different then it did before I cut the bumper. Extend the undertray into your air dam, make the center of the dam open to direct the air flow.

the only thing is that will get chewed up unless you plan to stay stock suspension forever.
