By replacing the stock pieces with the Granatelli's connectors and coils, you will improve spark, which in turn improves mileage, throttle response and adds power. Granatelli's spark plug connectors have 0 ohms of resistance, and no radio interference. This kit adds approximately 12 HP to naturally aspirated motors and about 25 HP to vehicles with forced induction or nitrous. Installs in about an hour.
