Well I've seen the caps go for anywhere from$130-$99. I bought mine of a guy who bought it new and said he didn't need it anymore. Purchase price$40 that's all I paid. So even if it doesn't make much of a difference I didn't pay much for it. Now using the resistor I got with it I charged them on my power supply then installed it. Made it super easy only took about 1 hr. to add it into my system because of having to cut 0guage wire and install reducers etc. Will make another video and I will let you know if it made a differance.
