I am going to be picking up an S202 on Monday and the car has an earthing kit fitted I have heard of people fitting them to Imprezas but what is the practical purpose of them?

 

I think that Impreza engines are not very well earthed, So this aids starting, charging and gives you a better radio signal...... there's probable lots of other things to...... they seem to earth JDM car a lot more.

Prior to purchase you need to spend a bit of time with a multimeter t check the earthing of the car. When I checked mine a bit of cleaning followed by a smear of copper based grease and all was fine. So no need for the earthing kit, IMO.

 

Snake oil, but can't do any harm, it won't weigh much either....

 

Thanks for the answers , TBH I think I will leave the earthing kit as is if it does no harm.
