The OE throttle valve spring is weak, resulting in low line pressures and insufficient throttle pressure for higher performance applications. Our stronger TV spring helps to maintain higher line pressure and improved throttle valve performance. This spring may be used with the OE valve configuration or the Sonnax replacement valves kits.
