Spark plugs.

[jonscott1972]

I am getting our van ready for a road trip and was wondering...has anyone tried E3 spark plugs? We will be driving from northeastern colorado to los angeles and I want to maximize my fuel use. I am planning to switch all my fluids to synthetic to help out too. Any help would be great..thanks.

Take pictures while you replace the spark plugs. A lot of members are curious to see what kind of challenge it is.

Spark plug replacement

I replaced plugs in my 92' 3.0L astar and it is a lengthy process, and will
remove some knuckle skin if you are not patient. Did it 3 yrs ago and it
took me several hours. Jacking up and removing the tires will help
greatly. Hardest one to get too is rear passenger side. blast the area
around plug wires and head with compressed air to clear debris from
falling into opening. Im doing a compression test on mine today and
not looking forward to it, but it uses a qt. of oil a week and I suspect
now that it is sooting up the plugs and causing a slight bit of rough
idling when engine is first started, but settles down once it goes to
normal idle, (engine warm). Put on some good music and enjoy!
