$400 for that??? jeeeeeez...
Here's the breakdown:
(Not really sure how it's "Easy" for Stazi, but anyways...
1. Plugs-Autolite/Motorcraft whatever you fancy= $4 a popx6=$24(double plats)
2. Wires-Motorcraft-Anywhere from $65-85 However the Ford Racing wires ae cheaper- I think $50 or so, but that's an iffy.
3. Tb clenaing-carb cleaner-$2-3
4. New air filter-Motorcraft-I think they're like $10-12
So you're looking at a bit over $100. You can definitely do the filter, plugs, and tb cleaning yourself. Wires will require the removal of the UIM, if you're up for it. Ask one of the guys in you're area, I'm sure the wouldn't mind helping you out.
