Thought I'd share my front end mod. I used a 3D printer to make the teeth. They are made so that they can be installed with no tools and require no hardware of any kind. They push in and stay put. I've had them on for several weeks now, went through brush-style car wash twice and no issues. I know they cover some of the cooling area, but I've had no heating issues at all to this point. The temp gauge hasn't moved from its normal reading. Cool weather now can account for that, but I don't think it will affect the cooling even in hotter temps. I have a good six months before it begins to heat up here in SoCal. What do you think?
