I was reading the October issue of Top Gear and i saw these items, and thought of installing it in my car.

Could you guys tell me the pros and cons of these?
Here are the short descriptions of these items.

RAIZIN VOLT STABILIZER BY PIVOT
cost: Php 3850
+Engine start easier
+ICE will sound better

GROUNDING WIRE KIT
cost: Php 1800
+Helps Efi engines run better by reinforcing the electrical system.

"To further improve car's electrical system combine the Raizin Volt Stabilizer with this grounding wire kit"

Worth getting or not?

I will install this in the Gen2 Crv.
