Mud/Stone Guards, Door Window Air Deflectors On A Prius
 

Has anyone installed Mud/Stone Guards, or Door Window Air Deflectors on their Prius?
Concern I have is if installed will they affect the Overall MPG?

I have the "Toyota" door window air deflectors on Pearl. They had no noticeable effect on fuel economy. They do make the car look nicer as well. I can leave the windows down an inch or so and water doesn't come in when it's raining.

Not sure what you mean by Mud/Stone guards. I have the stock Toyota "mudflaps" on all four wheels.

Have both on the wifes and no noticable reduction in her mileage. We have the Weathertech visors and the mud guards from Coastal Tech http://www.coastaletech.com./04prius.htm

Hi Bob 259; I noticed you have the coastal e tech auto door lock on your Prius.

Was it as easy to install as claimed? Does it work like it says?

Thanks, Robert

Well to be honest, I haven't installed it yet. It seemed a little more involved then indicated and I didn't have a lot of time to look so I'm waiting till the weather warms up to do anything with it. 10-20 degree weather :omg: is not the time to be playing with that or the plastics on the car.
