Injectors are an OEM Genuine part that is a direct replacement injector. Each injector has a $75 core charge and is fully refundable if they are shipped back within 90 days. All Industrial Injection / OEM products are covered by a one year/unlimited mile warranty. When replacing the injectors in your LB7 Duramax we highly recommend replacing the injector fuel lines to avoid new injector contamination. The most common failure of new injector installations is contamination and the problem that we see most on these comes from the fuel lines. NOTE: Fuel Lines MUST be replaced or sent in for cleaning to retain warranty! *All Industrial Injection Performance Products Are Not Legal For "On-Road", "Off-Road", or "Dual-Use".
