I don’t like the idea of these resistors. They can cause various problems such as a malfunction indicator light to come on.
What it will basically do is cause your engine to run a little fat. That will result in what's perceived as a performance boost, however, your engine will not like running this rich.
And, this resistor should only function until your ecu goes into a closed loop state; AKA warms up, at which point it will be ignored.
If you wanna use your car as a guinea pig, you can take a good look at whatever E-bay picture they have and go to your local R. Shack and buy the same resistor. They are designated by the various colored bands on them, so if you find one that's like the picture, you'll find what you need.
The seller may go ahead and tell you what type it is. It'll cost about $.02 to buy at a store.
