From The Driver Seat:Intake: The filter and the mass airflow assembly fit together through the heat shield, although it was a little awkward to get it right. Otherwise, it was a pretty standard installation.

Exhaust: This was easy as pie, and sounds pretty good, too.

Suspension: This was very simple, since it was essentially about replacing springs and shocks. There was no cutting involved.

Wheels and Tires: The Toyo tires and Eco wheels are a good-looking package on this vehicle.
