What's the best way to get to the spark plugs?  Jack it up and remove the front wheels?  Through the doghouse?  Any tips?Thanks!-Erik

If I remember correctly you can get to all of the passenger side plugs from inside and the rear plug on the drivers side from inside and the rest from underneath. Be sure to replace the heat shields on the plugs that have them, if you don't the plug wire boots will burn in short order.
