Thinking of putting on an add on voltage stabilizer. What do you guys think about these. I don't know much about them, except what the company claims. Just wondering if anyone here knew of anything. Thanks

 

a capacitor?

 

I am not sure if they are the same or not, but these are listed as voltage stabilizers

 

it is.

on later models, big capacitor is installed to prevent the voltage drop because the control units were more sesitive.

 

Are you having problems with voltage drops? if not leve it alone

 

It's funny. I purchased Sun Auto's Hyper Ground and Hyper Voltage systems for my Ford Focus. I have no dyno tests to prove it, but my engine idled far more smoothly, I had (what felt like) significant more torque, and great mpg (if I wasn't enjoying the HP too much)
HOWEVER, I transfer Hyper Voltage System over to the Benz but thought better of it. I really like the way my V6 runs and while I don't think the HVS could harm anything, why mess with a good thing.
BTW, before you deride this "electrical tuning" mod, both Toyota and Lexus are so confident of the benefits, they offer it as an option on their Japanese models.
