Why iridium spark plugs

Iridium spark plugs last the longest. Typically iridium plugs last for at least 96, km, and it could be as high as , km. Some vehicle owners do not even need to change the car plugs before they eventually sell their cars. So may as well consider it a long-term investment. Iridium is about six times harder than platinum, eight times as strong, and has a higher melting point at several hundreds of centigrade.

It takes considerably less voltage to fire up iridium spark plugs because of the tiny electrode at the centre. As such, it provides your vehicle with a more even spark. And consequently, you get a faster ignition and fewer problems associated with starting your car for the first time in the day.

The more voltage needed to produce the spark needed to start your vehicle, the more fuel is burned. With iridium plugs, minimal voltage is required, and so little fuel is used up.

Because fuel is burned more efficiently when you use iridium spark plugs, there is a decrease in exhaust emissions, leading to a cleaner ecosystem altogether. The tiny point electrode also increases the firing efficiency i. The combined effects of reduced fuel consumption and plug firing efficacy imply that iridium spark plugs help reduce exhaust emissions in ways that other spark plugs don't. Cars run faster and perform better when you use iridium plugs. You'll find that hills are also easier to climb since fuel burns more efficiently and overall power output is more efficient.

It is possible to clean and reuse iridium spark plugs. Thus, you get to make the most of using highly durable spark plugs in your vehicle. Concentrated Spark: The electrical spark that generates from the iridium spark plugs are highly concentrated and strong that helps in quick combustion.

This is reason why it has a small electrode present right in the center. Copper is one of the best conductors of electricity, which is why it is used in tubing and wiring. Thus, it should not be surprising that copper is also chosen for spark plugs. However, iridium makes the best spark plugs for several reasons. A major downside to copper spark plugs is that they have to be replaced soon because the heat inside your engine and the sparks produced make the copper start deteriorate with time.

It will bring down the performance of your engine considerably. Usually a 0. Service life can be as much as , miles for this plug type. Denso makes the OE parts for many vehicle manufacturers and therefore their aftermarket OE Iridium plugs are the best option to replace the original factory fitted plugs where available.

If a Denso OE Iridium plug is fitted as standard we would not recommend fitting any alternative part unless the engine is heavily modified. Most OE Iridium plugs are available from stock. A traditional ground electrode and a 0. Though not as performance orientated as Denso's Iridium Power, Tough or Racing plugs, the IX range does provide an extended service life and improved performance over standard copper plug types.

Not all NGK racing plugs incorporate an Iridium centre electrode. Those that do will have either a standard ground electrode design, usually in nickel alloy, or a solid platinum bar ground similar to the Denso racing design and a 0. Like the Denso Iridium racing plugs, these parts are designed for strength whilst maintaining optimum performance. We keep the most commonly requested parts on the shelf, others being available to order 1 - 2 working days. A fine Iridium centre electrode and an embedded platinum chip in the ground electrode add to the performance and service life.

The use of high grade materials superior to those of standard spark plugs prevents contamination, abnormal erosion and wear. Initial investment cost is high but overall costs are reduced due to the extended plug service life and improved fuel economy. We keep the entire LPG range in stock. Design is usually a 0. As with Denso OE, we would not suggest or recommend replacing an OE Iridium plug with an aftermarket equivalent, design would inevitably be slightly different and this will most likely have a negative impact on ignition efficiency.

A review of the iridium spark plug advantages and disadvantages can help you to find out! It can improve the acceleration profile of your vehicle. When you make the switch to iridium spark plugs, then you may notice an immediate improvement to your acceleration profile.

This advantage occurs because there is a faster response to your throttle operations. They can make a real difference when you live in regions where it is necessary to get up to highway speeds quickly to stay safe.

You may experience more engine power with iridium spark plugs. Iridium spark plugs can improve the performance of your engine with regard to its power. This advantage becomes apparent in situations where you need to climb steep hills or handle challenging driving situations. You will notice that the experience behind the wheel becomes more comfortable with the upgrade, giving you a smoother touring ability and more control as you navigate.

This advantage works exceptionally well when you have a variable transmission equipped to your vehicle. If you use a manual transmission, then you can still experience the benefits when your shifting is appropriate to the road conditions.

Your vehicle might start better when you upgrade to these spark plugs. The ultra-fine center electrodes of iridium spark plugs work hard to ensure that you have the best ignition experience possible.

Because there is so little dispersion in the position of the spark with this product, your idling also becomes more stable afterward. Iridium spark plugs can improve your fuel economy. Upgrading to iridium spark plugs can immediately improve your gas mileage on the highway or in the city. This benefit occurs because you have an improved ignition profile that allows your fuel to burn more efficiently.
