Hey everyone,

So here's an interesting question: What can I do, as many small modifications, to increase engine performance, without any changes to the overall body and without really getting too technical?

If this sounds like a beginner's question, it is. I have only a very basic understanding of the mechanical workings of cars, but I'm looking for little add-ons and replacement parts which would help engine performance. The theme here is little additions to create a bigger difference.

I figured I'd consult you all because it appears to me everyone here has a much better technical understanding than I do.

Any ideas?
