What performance parts are actually worth buying?

I have a 1995 Ford F-150 4×4 with a 5.8L engine. I was wondering what performance parts actually work cuz I hear good and bad about them. Which ones are worth the money? Headers, throttle body spacers, special spark plugs, etc?

    They all work with varying degrees. You wouldn’t know the difference in some of them unless you are on the race track where they could take time off your runs.

    For instance, a K&N could take off up to 0.2 seconds off your time depending on the engine buildup. For REGULAR safe and sane street driving it does no more help than any other filter.

    Unless you want to "race", no performance part is actually worth buying.

    I don’t think they do anything to help your gas milage.
