Are aftermarket ignition coils as good as OEM?

If you buy aftermarket coils that produce only 20K volts, they won’t work in your engine. It’s always better to play it safe with OEM ignition coils made just for your engine.


Do better ignition coils make a difference?

A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.


Does NGK make good ignition coils?

NGK ignition coils cover over 95% of vehicles in operation today. Each coil is tested to meet or exceed OE performance expectations. You can rest assured that the same product expertise engineering and manufacturing quality found in every NGK spark plug is inherent in its coil line.


Is it OK to use aftermarket ignition coils?

Aftermarket ignition coils are never worth the extra few bucks in savings. In a few cases, you can get away with using a cheap universal aftermarket part as long as it doesn’t affect: The engine’s performance. The vehicle’s safety.


Should I replace all ignition coils with spark plugs?

So, should you replace coil packs with spark plugs? It depends. The most common component to replace in conjunction with the ignition coils are the spark plugs. Worn spark plugs can cause unnecessary load on the coils and there is often some overlap in the labor required to replace both components.

Are Blue Streak ignition coils good?

Compared to the OE, the two Blue Streak® ignition coils tested had a 9% higher spark energy and 18% higher secondary voltage, which leads to better combustion of fuel mixture and reduced exhaust-gas discharge.


How long does an ignition coil last?

Average lifetime of ignition coil is around 100,000 miles or more. It is not an easy worn out replacement car part but still could fail for variety of reasons.


Which spark plugs are better Denso or NGK?

Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.


Where are NGK coils made?

The company has ten group companies, two production plants in France and South Africa and a Technical Center in Germany. Its European sales account for 26% of NGK Spark Plug’s global turnover.


Do new coil packs make a difference?

Generally speaking, coil packs are much more reliable than distributors, because there are no moving parts and because they fire much less often than a distributor. Coil packs usually create a better spark, which in turn produces better combustion and horsepower in a car’s engine.
