Front skid plate?

Hi guys so i needed a new front skid plate, I'm not even sure what it is called but it's the plate u take off to drain the radiator fluid, and if u look down where the bottom of the engine u can see the ground, with it on u can't see the ground, mines all busted up, the guy before me broke a bunch of screws, anyone know where I can get a new one?

If it's the piece I'm thinking of it's called the front air deflector.

That's it!! Thanks Matt I searched everywhere but couldn't find it because I didn't know what it was called

I've just been running without mine. There are a lot of hills around where I live and it would scrape frequently. Not to mention the fact that it's split along the edge.

Really? Me to but does it protect anything? I live in utah with all the salt and stuff, that's why I wanted a new one but if it's not really worth it I won't get a new one

I've noticed a dirtier engine bay, but nothing a bit of work won't fix. If you're worried about it just leave it on and deal with it.

Yah but that's the point, mine broke off lol, I might get one for next winter and take it off in the summer, could it help with gas mileage you think? On the highway?

I can tell you one thing, it protects those 2 front cradle mounts. When I replaced my cradle mounts, I bought all 6. The 2 front ones were practically mint. I had to chisel the other 4 off to replace them.

The main purpose of the air deflector is cooling. It is designed so that more air flow is directed through the radiator instead of around it. Most cars today have a series of baffles surrounding the radiator that direct most air flow goes through it. I would imagine this would also keep the engine bay cleaner as the radiator would serve as a filter.

Wow I didn't know that I'm gonna get a new one ASAP then
