I did my plugs and found out that 4 coils were cracked. The plugs arent that bad... Really! I did mine with simple tools and long extensions in 2.5 hours. May seem long may seem fast but the first 4 were easy and the four in the back sucked. Thats what took all my time. But, they came out and the new ones went in.
