Direct-fit EFI kit for 2004 applications

The MSD Ignition 2900 is a complete fuel-injection replacement designed specifically for 2004 fitment. It targets owners who want modern electronic fuel delivery without custom fabrication or extensive wiring changes.

Returnless design cuts plumbing work in half

The returnless fuel system design eliminates the need to run a second fuel line back to the tank. ECU-controlled ignition timing and self-learning technology adjust the air/fuel map automatically, so the installer does not need a laptop tune to get the engine running cleanly.

Bolt-on dimensions suit stock engine bays

At 21.00" wide, 10.30" long and 8.80" tall, the unit fits within typical 2004 engine compartments without major clearance work. The 15.50 lb assembly replaces the original carburettor and intake, but it will not support forced-induction builds that exceed the ECU's airflow calibration range.

Questions about this item

What maintenance will the 2900 fuel system need over time?

The returnless design eliminates a return line, so only the in-tank filter and injectors require periodic inspection or replacement.

What limit appears first during sustained high-load running?

The ECU-controlled ignition timing and self-learning fuel maps adjust continuously, so the practical limit is the injector duty cycle at peak airflow.

How much heat and noise does the 2900 produce during all-day operation?

With half the connections of traditional EFI kits and no second fuel line, the system runs cooler and quieter than conventional return-style setups.
