How to Confirm UF733 Fitment Before Ordering

Match the exact year, Mercedes-Benz model and 4.7L or 5.5L V8 engine.
Compare connector keying, coil body, mounting point, boot profile and printed references.
Confirm ZR6SII3320 for the exact engine.
Follow the vehicle manufacturer's spark plug gap and torque specification; do not guess.
Inspect wiring, connectors and plug wells for damage, oil or moisture during installation.

Diagnostic note: A misfire DTC alone does not prove an ignition coil is faulty. If symptoms remain, continue diagnosis of wiring, injectors, fuel delivery, intake or vacuum leaks, sensors, compression and mechanical timing as applicable.
