For the front Spark Plug Wires, make note of their positions before removal and twist the spark plug boot 1/2 turn and gently pry heat shield up from spark plugs with a spark plug boot removal tool (K J 38491) and remove the wires. Then remove the spark plug harness from the retainer and remove the air inlet grille. Repeat the steps for the rear Spark Plug Wires making sure that their positions are marked, twist the boots and use the spark plug boot removal tool (J 38491) while using the tool to pry the heat shield away before pulling out. Last, pull the spark plug retainers from the rear lift bracket and Fuel Rail.
