Stock inside wheel well covers and fuel economy?

I lost mine somewhere along the way, and besides having a wicked water leak as a result, I'm wondering if this would impact my fuel economy?

I'm not so sure how airflow in the wheel well works and is manipulated, but the basic issue is that now I have big, gaping wheel wells that are unobstructed up to the shell of the quarter panels.

Thoughts? Thanks

Haha, I was actually just emailing that guy. I wonder where mine went, lots of money to waste. Oh well though. It's probably better for aero anyway...

Off I go to investigate front lips for air dam purposes...

You are right it is a lot of money, junkyard would sell them to you for $15 bucks for both I bet.

I'm not totally sure about airflow in the wheel wells, but I tend to believe anything with a smoother surface has less resistance so a rounded well would probably be ideal (stock.)

The ones on my car, have integrated mudflaps in the front.. bummer! I found some that don't have that on there in the junkyard though, may have to switch!

wheel wells

Research published by SAE reports that wheel-house volume plays a measurable role in drag.Minimizing the volume lowers drag,so we can deduce that the absence of the inner fender well would increase drag by default.
