I just recently- July 3rd- picked up my new Mustang- a 2002 Roush Stage 2- and have a few questions for those more informed than I- which should be just about everyone as I am mechanically challenged- I was hoping for someone to answer four questions for me- in the above picture- marked with arrows and numbers- what are those engine parts that are marked- and their major function? I have a basic understanding of some of the components of the engine, but basic as in- oh- thats where the oil stick is and such. Thanks in advance for all answers and help!!!!
