Best Ignition Coil For Performance Engine FAQ

What is the biggest advantage of upgrading to a high-performance ignition coil?

The biggest advantage is increased voltage and energy output, which translates to a hotter, longer-duration spark. This allows for more complete combustion, especially at high RPMs or under boost, helping to prevent spark blowout and improving overall engine response and horsepower. A strong best ignition coil for performance engine ensures consistent power delivery under all conditions.

Do I need to upgrade my spark plugs when installing a performance coil?

While not always mandatory, it is highly recommended. High-performance coils produce much higher energy, which can wear down standard copper spark plugs quickly. Upgrading to a quality plug (like iridium or platinum) designed for high heat and high energy ensures you can fully utilize the coil’s potential and maintain proper spark plug gap without degradation.

What is the difference between a canister coil and a coil-on-plug (COP) system?

A canister coil (like the Pertronix) is typically found in older vehicles; it sends high voltage through a single wire to the distributor, which then routes the voltage to the plugs. A COP system (like the TRQ or DG508) has a coil directly mounted on top of each spark plug. COP systems offer superior voltage control, eliminate high-voltage wires, and allow the engine control unit (ECU) to precisely control dwell time for each individual cylinder.

Does a higher-voltage coil require a specific resistance rating?

Yes, especially for older vehicles. Canister coils are typically rated by primary resistance (measured in Ohms). If you use a coil with too low a resistance value without an external ballast resistor, you risk overheating and damaging the coil or the ignition module/points. Always check the required coil resistance specified by your ignition system manufacturer.

Will a performance coil fix my engine misfire issue?

If the misfire is caused by an old, weak, or failing coil, then yes, installing a best ignition coil for performance engine will likely resolve the issue. However, misfires can also be caused by bad spark plugs, faulty fuel injectors, compression loss, or vacuum leaks. It’s important to diagnose the root cause; replacing old coils is often the easiest starting point.

What is “dwell time” and how does it relate to performance coils?

Dwell time is the duration, measured in degrees of rotation or milliseconds, that the coil is charged before the spark is released. Performance coils, especially on COP systems, can handle optimized dwell times (often slightly longer) to store maximum energy, leading to a stronger spark. Modern ECUs are usually calibrated to maximize the dwell time for the coil being used to ensure maximum spark energy delivery.
