Useless for you? Or useless for every 4.0 (including F/I cars)
Useless for you:
Headers: shorties or longtubes (maybe LT's are worth like 2 ponies...)
Dual Exhaust (compared to single aftermarket axle-back)
TB Spacer
Coil Pack
Ignition Cables
Larger Injectors
Useless to everybody:
TB Spacer
Coil Pack (seems so according to Doug)
All the things that I put as "Useless for you:" that did not appear in "Useless to everybody:" do help F/I applications. Also, a good throttle body can show some very nice gains. A new TB that was just released made 9rwhp on an X charged system, with no tuning. Apparently it leans the cars out a bit, so with tuning you will for sure see more power. I actually bought one today, and am getting it installed and tuned for with a bunch of other stuff in about 2-3 weeks. This TB is from Zabteck Perf. It is the best system for our cars because it uses the stock electronics and housing, meaning that the electronics remain stock and untouched. It is a bit more expensive than most TB's, but it is worth it. Plus, for an introductory price, they are have a $50 off special until the end of this month.

Throttle Body Spacers only add weight and nothing else.
Cold Air Intakes without tunes are a waste of money.
Adj Panhard bars with stock size tires and lowered less
that 1" are pointless. Upper strut tower braces add weight
and nothing else (IMHO)unless they are the three point
kind and tie into the firewall. Aftermarket SUPER SPARK
PLUGS are a waste unless you are supercharging and need
a colder plug. Plug wires are aall show and no go add on.
Non functional hoodscoops.......
