Overall the K&N Install instructions are excellent. Head and shoulders above other manufacturers that point you in the general direction of the car and then have numerous text only: "do this, do this, BUT first" style instructions! My few gripes: a heat shield mounting stud location was identified incorrectly and the crankcase hose needed to be trimmed to fit without kinking. A couple of the pictures could have been clearer. The performance increase was noticeable immediately and the increased roar limited to when you tromp on the pedal.
