"Instructions took you through the process step-by-step. Took some time though, make sure you have the right tools (metric sockets, allen wrenches, car jack(under driver's seat), lug wrench, etc). Taking apart/reinstalling the under-fender parts was a bit tricky & some of the parts you have to unbolt were in tight places and often difficult to get loose (try to avoid stripping bolts). I put silicone around the headlight to ensure no water leaks through on rainy days. Product has a nice appearance, but there was no real sound difference or noticeable horsepower increase (so in my opinion not really worth the $$ spent on the system). Overall, just a fun project for my Dad & I could work on." —Michael O from Baton Rouge, LA bought an AEM Cold Air Intake System for a 2009 Toyota Yaris.
