My 2005 4.3 V6/5 Speed W/T will be hitting the 100,000 mile mark within a week or two. I have had the truck for the past 50,000 miles and all I've done is regular oil/filter changes. Planning on plugs/wires and gas filter change along with air and oil filters this time around. Anything else I should look at and/or change at this mile mark? With so many types of spark plugs is there any recommends for plugs or wires brand or type? Thanx in advance! -Pete.
