Comparison Insights

When looking for the best ignition coil for dodge 318, your choice depends heavily on the engine year and your performance goals.

If you own a classic 318 (pre-1990) still running points or early electronic ignition, HEI conversion kits (A-Team Performance, LaMulaAuto, AiYiGu, MAS, JDMSPEED) are the gold standard. They eliminate the external coil and ballast resistor, boosting spark energy significantly. A-Team Performance stands out for its proven track record and high 65k output.

For later model 5.2L Magnum engines (1992+), your ignition system is vastly different. The DRAGON FIRE PERFORMANCE Power Pack is the premium choice here, offering a comprehensive performance upgrade including low-ohm wires, which is crucial for maximizing power in these EFI systems.

If your vehicle is a later-model Dodge and you need a simple factory repair, Spectra Premium C-624 is an excellent standalone coil known for its OE fit and superior component quality, especially the copper windings. The OEG Parts coil is also a great value replacement for specific late-model applications.

Don’t overlook the importance of accessories: If you choose an HEI distributor, invest in quality wires like the A-Team Performance Red Silicone Spark Plug Wires Set to handle the increased voltage output effectively.

Final Verdict

Choosing the single best ignition coil for your Dodge 318 depends on which generation of the engine you own and what you plan to do with it.

The A-Team Performance High-Performance V8 HEI Ignition Distributor takes the top spot. It delivers a proven 65,000-volt punch, simplifies the wiring with its one-wire setup, and provides the ultimate reliability upgrade over points or early Mopar electronic ignition systems.

Best Comprehensive Kit for Magnum 5.2L (1992+)

The DRAGON FIRE PERFORMANCE Power Pack is unbeatable for later-model 318/5.2L engines. This complete solution ensures all components—coil, distributor, and wires—are perfectly matched for maximum performance gain.

Best OEM Replacement/Reliability

If you require a simple replacement for a stock system (canister style or later model pack), the Spectra Premium C-624 Ignition Coil offers superior construction, 100% copper windings, and rigorous testing for long-term dependability.

Best Ignition Coil For Dodge 318 FAQ

Q1: Why should I upgrade my factory ignition coil on my classic Dodge 318?

A: Older factory ignition systems (especially points) generate a relatively weak spark. Upgrading to a high-output coil (often integrated into an HEI distributor) significantly increases the voltage and spark duration. This leads to more complete combustion, resulting in better throttle response, easier starting, smoother idling, and potential small horsepower gains.

Q2: What is the benefit of a HEI distributor conversion for the Dodge 318?

A: HEI (High Energy Ignition) systems integrate the ignition coil and electronic module directly into the distributor cap. The main benefits are a much hotter spark (60k+ volts), the elimination of the external coil and complicated ballast resistor wiring, and the removal of maintenance-intensive ignition points. This offers simplicity and vastly improved reliability.

Q3: Do I need a ballast resistor if I install a new ignition coil?

A: If you are using an OEM-style replacement coil designed for classic Mopar electronic ignition (or points), you almost certainly still need the ballast resistor to drop the voltage from 12V down to the 7-9V required by the coil during operation. However, if you install a one-wire HEI conversion unit, you must bypass or completely remove the ballast resistor, as HEI coils require a full 12 volts to operate properly.

Q4: Will a high-performance ignition coil require new spark plug wires?

A: Yes, it’s highly recommended. High-output ignition systems, particularly 65,000-volt coils, can sometimes “leak” through low-quality or old spark plug wires. Always pair your new high-performance coil with quality, high-resistance wires (like 8mm silicone) to ensure all that spark energy reaches the spark plug tip.

Q5: Are the components used for the early 318 (LA block) the same as the later 5.2L Magnum engine?

A: No, they are fundamentally different. The older 318 LA engine uses a traditional distributor and typically an external canister coil. The later 5.2L Magnum engine (1992+) uses a different distributor design that triggers a coil pack or separate coils (depending on the year) in a more modern electronic fuel injection (EFI) setup. Always double-check fitment for your specific model year.

Q6: Can a faulty ignition coil cause my engine to misfire or run poorly?

A: Absolutely. A failing ignition coil cannot produce the required voltage, leading to a weak or intermittent spark, especially under load or high RPM. This often causes engine misfires, rough idling, poor acceleration, and difficulty starting. Replacing a weak coil with the best ignition coil for dodge 318 performance is a common solution to these issues.
