i had a real Sun Auto grounding kit lying around leftover from my Evo. I installed it in my current integra. guess what? i cant really see any immediate differences. However, i havent been on a dyno with this car, nor did i make specific back to back before and after tests with the kit, so my experience may be different than someone eles's integra that has poor/broken/worn grounds. A stock B18B cant be pushing that much WHP (110-115whp realistically) anyway, so any improvement will probably be unnoticable. Am I un-installing the kit? no. i'm sure the factory ground wires have seen their 171k worth of miles, so I'll give em a break.

In a modded evo where its easily triple the power of a B18B (mine was), its been well documented the improvements a grounding kit can make since the factory mitsu stuff is pretty meager. Upon installation, idle and throttle response were immediately noticable.
