Review the hidden work

On the final pass, compare your hardware inventory and before/after photographs. Account for the harness clip released underneath the old box and the connections transferred to the new assembly. If the installed part number or bracket shape differs from the illustrated kit, ask K&N to identify the revision before modifying the vehicle. Keep the original intake intact and label its parts for a later return to stock.
