I think its time for a tune up on my 03 Edge 3L. So far i know i want to replace/upgrade the plugs, wires,and coil pack, clean the MAF
sensor, clean air filter, and upgrade the underdrive pulley. I have already replaced the camshaft position sensor and put in a K/N filter. Ill probably be ordering most of this stuff online.
1. Who makes good/high performance plugs, wires, and coil pack?
2. Where can i find the upgraded underdrive pulley?
3. What else should i do to my truck? upgrade the cat. convertor? I heard about this 'sea foam' stuff that cleans out the entire engine...is that worth it?
