#9 resister
 

Any one ever added one in place of there stock #5? Says it will add hp.. ???? Worth the money or not?

$20 for one I woulod say you would have to put it on a dyno to see the HP gain I have a #9 on my truck was in it when I bought the truck and i like the way it runs

You won't notice a difference. I wouldn't waste the money on it. The only time I would buy one is if you don't have a resistor to put in and halve to buy one any way.
