Best Spark Plugs 2019 Buying Guide
Before going further we need to know a few simple facts about the spark plugs. Firstly, while choosing a spark plug there is no “one size fits all” in this case. So you need to search for a spark plug that fits your vehicle (the thread diameter and reach, the insulator nose projection and incorporated gasket or conical shape) and it’s better to stick to the owner’s manual for the type recommended. Secondly, sparks travel from the sharpest point in the central electrode to the sharpest point in the side electrode. So, the longer the electrode edges retain their sharpness, the longer or more miles will the spark plug last. Thus harder metals with high melting point like platinum and iridium are preferred over the nickel alloy electrodes found in traditional copper spark plugs. Thirdly, the smaller the diameter of the central electrode the lower is the voltage needed to start the spark.
Types of Spark Plugs
- Copper Core Spark Plugs
- Iridium Spark Plugs
- Platinum Spark Plugs
- Double Platinum Spark Plugs
The details about every type of the Spark Plugs you should take a look as they are different in cost and quality.
1. Double Platinum Spark Plugs
These have the longest life span and had been specially designed for the “waste spark” DIS wherein the spark travels from the center electrode to the side for the cylinder in the combustion stroke and then back from the side to the center for the partner cylinder to return the electrical impulse to the ignition coil. The center tip as well as the side electrodes are welded with platinum for the reverse spark effect. These can be only upgraded to iridium-platinum combo plugs where the side electrode is platinum welded.
2. Copper Core Spark Plugs
The most inexpensive ones available in the market, the copper spark plugs will last you around 20000-40000 miles. Made from a solid copper core and a 2.5 mm diameter nickel alloy center electrode these tend to erode quickly, the edge looses its sharpness and require a higher voltage to ignite a spark. But being the most conductive out of the four types they provide the highest level of performance which lasts only for a short duration and hence lacks longevity. They are best for older (pre 80s) vehicles and some late model high performance engines that have been designed for copper spark plugs. It’s recommended not to upgrade to spark plugs of higher metals if the owner’s manual asks you to use a copper spark plug.
Know check the iridium vs platinum spark plugs below.
3. Platinum Spark Plugs
A single platinum spark plug is a step up from the copper spark plug wherein it is styled on the copper spark plug with a platinum plate welded on the centre electrode. Platinum can withstand high temperatures and prevent depositions or fouling and also holds the sharpness of the edge for a longer period of time. These spark plugs can last for a good 1,00,000 miles and are ideally suited for vehicles with electronic distributor based ignition systems (DIS). A platinum spark plug can be upgraded to double platinum or iridium spark plugs but never downgraded to copper ones.
4. Iridium Spark Plugs
Iridium is the hardest metal used in spark plugs but the least conductive. So they tend to last 25% more than even platinum ones. Owing to the high cost of iridium, manufacturers reduce the diameter of the center electrode to as low as 0.4mm. This is not only reduces the cost but also increases the firing efficiency and operate at a much lower temperatures thereby increasing the longevity. The iridium spark plugs are best suited to cars with COP ignition systems and cannot be downgraded to any of the above mentioned spark plugs for optimum performance.
So after referring to the owner’s manual of your car and following the instructions mentioned along with a detailed study of this best spark plugs 2019 buying guide you can choose your spark plug wisely and enjoy a hassle free smooth drive that would also ensure optimal fuel efficiency. Hope it answers your questions and queries regarding spark plug reviews.
