    Regular Price: $139.99

    Special Price $79.99

    2JR's Heavy 2 Gauge 5 Point Ground System - the best is finally here. Direct fitment, attaches to the battery, ground point on the drivers fender, to the head, to the passenger shock tower and finally to the alternator bracket. Full grounding of the engine bay. 2J's Sport Ground System can't be compared to anything on the market. High Grade Wire, Silver Crimped Ends, Perfect Fitment! Any electrical component requires power and ground to function properly. If you have a stereo system, HIDS, Fogs, Interior lights and have a bad ground, you will get poor performance from your system. The same is true for any part of the electrical system of your Sentra. If the electrical system has a bad ground, or a barely adequate ground, you can get lower gas mileage, inefficient spark, slower window motors and dim lights. When you add 2JRs Sport 5pt Grounding Kit, you add more grounding points to your B15 to allow your electrical system to function at full capacity, which can make every electrical component operate more efficiently, often increasing horsepower, delivering better gas mileage, and crisper stereo systems Learn More
