◆Cable Color◆ Red ◆Principle◆ Earth current flows back from electrical equipment to the battery (-) via the body (steel plate), but various electrical resistances exist in that path, and the resulting resistance and noise adversely affect the electrical equipment. Therefore, by connecting an earth cable from the vehicle body and electrical equipment to the battery negative terminal, the flow of electricity is dramatically improved, significantly reducing losses in the electrical system and improving the efficiency of the electrical equipment. ◆Expected Effects◆ ① Improved starting performance ② Stable idling ③ Improved engine pickup ④ Increased torque in the low and mid-speed ranges ⑤ Increased power in the high-speed range ⑥ Improved fuel efficiency ⑦ Cleaner exhaust gas ⑧ Improved power generation and charging capacity ⑨ Reduced noise, improved sound quality, and improved reception sensitivity of onboard AV equipment ⑩ Increased light output of headlights and room lamps, etc. ◆Earth Points◆ The earth points are ① Alternator ② Distributor ③ Injector ④ Throttle body ⑤ Igniter ⑥ Intake manifold ⑦ Surge tank ⑧ Bulkhead ⑨ Left and right struts ⑩ Engine head ⑪ Engine block ⑫ Near headlights, etc. The optimal locations are selected for each vehicle model, considering the installation work. ◆Points of Emphasis◆ ① Includes a vehicle-specific "color installation manual" with enlarged photos of the earth points. *Also includes "secret techniques" that make a difference in the effect. ② No troublesome work such as removing auxiliary equipment (excluding engine covers, belt covers, etc.) or jacking up is required. These are vehicle-specific products (pre-measured, cut, and crimped terminals), so they can be easily installed in about 30-120 minutes. *Installation is possible for those who can use a spanner, box wrench, or ratchet wrench. ③ Considering the engine heat and electrical capacity (alternator's power generation of about 70A-80A), high-efficiency 8-square KIV standard copper wire with a heat-resistant coating (about 110°C) from a leading domestic manufacturer is used for the cables. ◆Delivery Time◆ It takes about 7-10 days from purchase to delivery. Please note that delivery may be delayed on weekends, holidays, Golden Week, and the year-end and New Year holidays (December 27th to January 5th). ◆Caution (Please read carefully)◆ The effects vary depending on the vehicle model, vehicle condition, and driving style. We are not responsible for any damage or trouble caused by installation. Please purchase only if you understand and agree to this.
