The Mazda front mask is fairly easy to install. The only tool I needed was a stubby Phillips screwdriver to replace the wheelwell screws. I found that a regular length screwdriver was too long cause the tire was in the way, even turned hard left or right.
Altogether the install took me about 30 minutes. You might want a friend to hold one side down for you while you stretch the mask across the front end. It's a tight fit, but that's what happens with form-fitting accessories.
Important tip: Always COMPLETELY remove the mask before washing the car. You'll be amazed and disgusted with how much crap gets underneath, which is no good for the paint. :mad: I'm considering leaving the mask off for the summer... maybe.
