I think I've heard of these before. I don't know that I've heard anything about how well they do or don't work though.
I think Mpgmike said he was going too test that?

I'm pretty sure they are just a small capacitor that helps even out the voltage spikes from the injectors turning off and on.
$4.99 each, I see! I'd guess that at Radio Shack or anywhere like that, you could get a big bag of these for $4.99.

That would be my guess. The tricky part may be in finding the capacitance value. That could require a guinea pig to buy one and do a postmortem exam. :wink:
let's paypal someone 1 dollar each so that they buy one and find out what it is.
0.1 uf according to [url]http://piccquote.com/PDF/HAFC_TrainingCourse.pdf[/url] - not that I am at all sure there is any benefit to the things.
Here: [url]http://www.autonerdz.com/cgi/yabb2/YaBB.pl?num=1212494356/5[/url] is some interesting info I found.
Holy crap is that an old version of the manual! We've updated that thing several times since that version (10-20-08 being the last update).
I played with caps of a variety of capacitance ratings and found that as you use a larger capacitor, you dump more fuel. We were able to practically flood a Ford Excursion with 25 uf caps. On a Kia, anything above 4 uf would practically shut it down. While tuning a late model Nissan, the addition of the 0.1 uf caps on the injectors meant the difference between no gain and a 50% gain, all else being equal. The "dixie caps" did the trick.
These caps come in different voltage ranges....from lower ranges like 50v up to higher....like 250v.
Does the voltage matter?
Here is an example:
Voltage tolerances for capacitors don't, in general electronic usage, matter as long as they meet, or exceed, the circuit's voltage. Injectors on cars run at 12V nominal, so 50V is sufficient.
However in this kind of application, who knows? Purple ones might work better than black ones!
Sweet, then I'll definitely go purple!
BTW, hypothetically, what would happen if we put say a 0.1 ohm resistor on the fuel injection wires instead of a 0.1 micro farad capacitor......you know....for kicks? Humor me.

If you went "across" (parallel to) the injector with a 0.1 ohm resistor you would either burn out the wiring harness or melt the resistor (more than likely the resistor will instantly smoke).
If you went in-line (series with) the injector it wouldn't make any measurable difference.
