05 hood rubber inserts

so the rubber inserts when u pop the hood that go in the hood scoop well can be popped out, is there any downside to doing this, i know i wont really see any performance gains but maybe it will keep the engine a little cooler.

Keeping the engine cooler will produce performance gains. I removed my fuel rail covers and hood plugs at the drag strip and did some playing around. The car cools a lot quicker between runs without the plugs and fuel rail covers. In the summer I also noticed a difference of 1-2 tenths due the engine not heating up as much in the staging lanes and during staging.

That is what ferg was referring about. I took mine out and only put them in when it's raining and when I was it. As far as performance, maybe a little. The more air you have running through your scoops the better to keep your motor cooler.

I took mine out and the motor does seem to cool down a bit better. I've left them out in a few of our FL rain storms and nothing's happend. However i've noticed more dust building up in the enginge area with them out. I'm having to wipe it down twice a week now.

Same thing happened here as far as dust, dirt and bugs on the engine. I never put mine back once I took them out. The fuel rail covers protected the coil packs though so the only time I took those off was when I was at the track.

I've haven't noticed any dust(now you are making me paranoid) but I forgot to put them in one time when it was raining and the motor was pretty wet.

maybe put some mesh or some little crappy filters in place of those rubber baffles? Might cut down on that dust buildup and keep water out.

I was thinking around those same lines. Maybe over lap the existing screen with some type of mesh screen. Definitely would help out with bugs but I doubt it would help with the water issue.

When I'm at speed--say, 80 or so on a freeway--I've noticed that the hood shimmies a bit. Just keep an eye on the panel gap between the driver's side front fender and the hood and see if you don't notice it, too.

I have a notion that whatever air is getting through the hood scoops (I've left the rubber inserts in place) is causing a bit of lift under the hood, making it vibrate a bit. I'd be curious to know if '04s do the same thing, or if their hoods sit still.

Anyway, I'd imagine that taking the inserts out would only increase this phenomenon in steady-state cruising at speed.
