FAQ
Will this injector increase horsepower?No—this is a stock-flow AD-code reman designed to restore OEM performance and reliability.
How do I confirm AD vs AE code?Check the white tag on the valve cover harness or scan your existing injector code. Many 2003 trucks use AE; E-Series often remained AD longer.
Do I need tuning?No tuning is required for stock AD-code injectors.
What else should I replace during installation?At minimum, replace the injector O-rings and inspect the valve cover gasket/UVCH. Consider fresh glow plugs and sealing the fuel filter housing if it seeps.
