2006 Duramax Competition Injector Max Output 580cc (521COBRA5184)

Industrial Injection 580cc Cobra Series competition injector for the 2006 LBZ 6.6L Duramax. The maximum-output option in the Cobra lineup for this application — built for race and competition trucks pushing past what smaller injectors can support.
