Hey everyone I'm new to this forum and I have a 2.3 4cyl Mazda 6. I wanna Start by asking if anyone has upgrade their factory grounding system to an after market grounding system. Every car will have different affects from doing this but i read it never results in a power lose. So if you have done this mod please state to what car and if it resulted in any power gains on a dyno or have just plan noticed more power.
 
I think your money would be better spent on other items directly associated with the engine. Intake and exhaust would be my first move, not a grounding kit.
 
I agree with you guys .both those upgrades are in the works.But i was just wondering if anyone has put an after market grounding kit on and if you could tell a difference in power at all.
 
I got the JDM Apex-i grounding kit.
And yes, throttle response is a lot more sharp.
My intake is CP-e
