Ya it is called that. On Carbed engines they may. On FI they don't work. And Throttle body spacers that fall into this category too. They my work on carbs but not FI.

1) K&N drop in air filter.
2) Remove restriction to air filter. There is an air tube that goes off the air filter to the grill. There is a block off tube over this tube at the grill that restricts flow. Take this piece off and cover the hole with some screen.
3) Tune-up. Running good plugs, dist cap, wires, rotor and good fuel filter helps performance.
4) Check ignition timing. Sometimes timing can be off and affect performance.
5) Exhaust. I put a Magnaflow cat and Heartthrob cat back exhaust on my Dakota.
6) Headers. Edelbrock makes nice headers that bolt right on to the 3.9 V6 pre-magnum engine.
7) Intake/carb. I believe that Mopar Performance had a 4bbl intake available for these engines, but not sure how easy they are to find.
I've done mods 1-6 to my 90 Dakota Sport and the improvement was noticeable.
