In my opinion, you are going to get the best performance, and economy, with the plugs the vehicle was manufactured with. Others may claim improvements, and I think that is just a catch to get you to purchase their product. You can get them from the top, the rh rear plug(#8) is going to be the most difficult. Often times the plug wire boots can be a bit of a struggle to release.
