Top 12 Best e3 Spark Plugs Review

Do you know what affects the quality of your smooth drive? It's your spark plugs. Yes, those tiny and tough critters -made to screw into your car engine and deliver the pack of electricity have a lot to do with the quality drive you get.

Typically, the car spark plug is generally a simple device but a spot on for withstanding intense pressure of heat and electricity. These plugs are strong enough to withstand years of continued jarring and vibration.

A quality spark plug has high endurance power and tops on performance meter. Its top-notch metal tips can withstand constant sparking. The material of such spark plugs are compatible coefficients of expansion; thus, the heat doesn't cause them to crack.

As you can now understand that these little spark plugs are much more than they seem. But, if you're still not sure about why it is essential to invest in a good spark plug, read on.

Why is it Important to Invest in a Good Spark Plug?

We know for a fact that investing in a quality spark plug often goes overlooked. This happens especially when money is tight, and we don't pay much attention to replacing spark plugs. It's that time everybody is trying to cut back on any non-emergency auto repair and maintenance items. But, I have some super-rational reasons that should convince you to invest in a quality spark plug. There we go:

Reason:1 New quality spark plugs are good for your engine's performance and efficiency levels. That is obvious every car on the road misfires from time to time. But as soon as these misfires become frequent, they also become troubling. Recurring misfires implies added exhaust emissions, reduced power, and wasted gas. Misfires led by worn car spark plugs cause older cars to stall, buck run rough, or start slower than ever. All the vehicles manufactured since 1996 have OBD II onboard diagnostic systems that trace misfires and sparks a warning light. 

Reason 2: Brand-new spark plugs can improve cold starting of your car. Worn or dirty car spark plugs need higher voltage to have a strong spark to start a car. As soon as you crank the engine numerous times, hoping for an eventual start, you may have made your battery dead. This brought you two problems now. Having to use a quality spark plug means lesser voltage requirement, which lessens the chances of an ignition misfire and leaves more amps for the injectors. 

Reason 3: If reasons 1 and 2 weren't good enough to convince a car owner into buying a quality spark plug, this one is sure to do it. Good quality spark plugs will lessen the risk of catalytic converter failure. Only one misfire and you will have enough draw fuel into your car's exhaust, which can lead to overheating and damaging. Consequently, the extra load of unburned gas in the exhaust will jack up the operating temperature of your converter. This may cause a meltdown of the converter substrate. This, in turn, will create a blockage of the exhaust, choking your engine. Your car may work, but it won't have the power and consume more fuel.

To sum up, when it comes to change your old spark plugs, it is like, "pay a little now or a hefty cost later." However, if you choose E3 spark plugs, you are sure not to pay the heftier price later. But, there is a vast range of E3 spark plugs out there, designed for different conditions and vehicle.
