Pros
It made power, installed in five minutes and looks good underhood. The A'PEXi Super Ground Stabilizer is universal to vehicles with electrical systems, meaning it can be easily transferred from one vehicle to another. And it's an all-inclusive product-there aren't any parts to lose in the shuffle. The included installation guide identifies grounding locations for popular platforms, and gives a good idea of where to fasten grounds in universal applications.
Cons
Negative reputation. It seems most people are slow to trust grounding systems in general, and we're sure we'll have to defend our reasons for adding the product to at least a few clowning skeptics every time the 240's hood is propped. Applying the kit to the SR20 engine required we attach one of the wires to the coil harness grounding point on the firewall side of the cylinder head-not the easiest place to access, especially on a hot engine. Nissan takes the heat for this "bad".

Notes
Efficient electrical conductors (like wires used for engine grounding) are made of expensive copper, so, it goes without saying that OEMs will limit the application of ground wires from the factory to reduce production costs. Adding more grounds can often times be beneficial, but only when done correctly. Ground wires should be applied to stock locations as well as points where electrical noise might occur among sensors and other devices; DIY kits with more grounds or thicker wire than necessary won't result in more power. The A'PEXi kit includes just enough additional grounds at the right gauge to tame electrical noise and properly channel rogue currency back to the battery ground. It also offers an active voltage-stabilization control unit which further smoothes turbulent current with its electrical noise filter; something not found in DIY kits.
