Scope of application: generators, , air-conditioning compressors, engine blocks, automatic transmission boxes, frames, etc. Advantages: Strengthen the current loop of each electrical aging circuit and restore its performance; enhance high-voltage ignition, make combustion more complete, save energy and increase torque; reduce power loss and extend battery life; start smoother, louder horn sound; idling speed More stable; faster response and faster acceleration. High quality: Each end is welded with copper ring terminals to maximize contact bonding and heat shrinkage to that everything is not weathered. Note: Recommended for old cars, professional installation is strongly recommended. If the installation is wrong, it may cause poor contact and the performance will be worse! colour:Red Material:PVC Package Contents: 2 x 100cm grounding wire 2 x 80cm ground wire 1 x 60cm ground wire 1 x screw kit Only the above package content, other products are not included.
