My 05 seems to be sluggish. Want to change the plugs and wondering how difficult it is to do that. Also looking for recomendations on plugs.

The plug replacement job is difficult. Access to #4 is very tight. There are many posts addressing the issues you face, so a little research of the site is warranted.

As for a recommended plug, the OEM plugs for the engine are a very good choice. Your engine should be COP, Coil-On-Plug, so some Bosch P+2 plugs would work well....a set of those plugs in my '94 LTC 4.6L returned improved performance and a little better fuel mileage compared to OEM plugs or the Autolite equivalent.

Its easy as pie. Prolly take you 1 hour or so and use motorcrafts or autolites.

Be cautious use highest quality tools. Extreme care with plug hole threads. Platniums please.

and x2 on the platinums even double platinum is great too.
