They are really not hard to replace. The book time is one hour and you just want to twist the boots of and not pull them. The anti-seize is a very good idea with the aluminum heads, (I always use it)
Then, with a spark plug socket and an extension they are pretty easy to do. You also want to apply equal pressure when tightening them up, so that the socket doesn't put pressure on the new plug.
Spark Plug Replacement Removal Procedure Notice: Observe the following service precautions:
Installation Procedure Notice: It is important to check the gap of all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. Use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine. Notice: Be sure plug threads smoothly into cylinder head and is fully seated. Use a thread chaser if necessary to clean threads in cylinder head. Cross-threading or failing to fully seat spark plug can cause overheating of plug, exhaust blow-by, or thread damage. Follow the recommended torque specifications carefully. Over or under-tightening can also cause severe damage to engine or spark plug.
Notice: Refer to Fastener Notice.
Tighten the plugs to 20 N.m (15 lb ft).
Hey thanks for the answer. Unsure as to torque spec, one place indicated 15 N the other 20 N. Please clarify.
