Hi Guys, I just got me an escape 2009 3.0L Does tuneup only involves changing the spark plugs or there's something else? what it the most compatible spark plugs for ford and how much they cost? where to buy? im new to this, i just thought it would save me money if i just buy a spark plugs and have a technician intall them. Will be waiting for your help. thanks in advance
