Sport V.2 Counter Spring. This current version of the Naraku tension spring uses a modified alloy spring that provides better strength and above-average durability. Replacing the spring is essential when tuning engines, as it prevents initial resistance from the variator, thereby increasing engine speed. Delayed engagement will boost power during startup. The markings on the spring help you identify its durability.
