spark plug types comparison

In addition, carbon core breaks down more quickly than other materials so they require relatively frequent replacement. So if you have a stock engine it’s better to just use the spark plug which has been recommended by the manufacturer. We’ll start with one … The most common types of spark plug wire cores are as follows: Carbon Core: This is the common OEM-style core used on most modern vehicles. The single platinum spark plug is based on the copper spark plugs but the difference between the two is the platinum plate welded on top of the center electrode. NGK SPARK PLUGS. This created a plug that is very durable in DIS systems, lasting upwards of 80-100K miles. This point we will discuss below. To make this even more complicated, one spark plug attached to each coil is positive polarity, while one is reverse polarity. compare NGK spark plugs with Champion, AC, Denso, Bosch, KLG and Auto-lite Spark plug … Platinum spark plugs are also slightly hotter, preventing fouling.

ACDelco 41-993 Professional Iridium Spark Plug. Both Platinum and Iridium also come in a “double” variant, which will be explained. Nickel is softer than platinum or iridium, and thus has a much shorter life. The metal center of spark plugs is exposed only on the ends. Since the platinum plate is stronger than copper so it lasts longer for around 100,000 miles. Platinum plugs use a platinum disc that is welded to the end of the center electrode, which allows the plug to last longer than a copper plug, retaining its edge better, which means better conductivity. Latest vehicles operating on electronic distributor based ignition systems are better suited to the platinum spark plugs. Granted, the plug will work, but will wear prematurely and not perform as well. If your car needs new spark plugs and needs replacement you should be able to do it fairly easily and quickly by yourself.

If your manual specifies iridium spark plugs, best practice is to absorb the extra cost associated with this rarer metal for best performance. This is one of the most asked question related to spark plugs and the answer to this question is fairly simple. On the exhaust stroke the spark returns from side electrode’s platinum plate to center electrode’s platinum plate, since the combustion process is going through exhaust stroke, spark is wasted and ignites nothing. NOTE: Cross references are provided as a guide only. The second factor is the diameter of the center electrode. Champion spark plugs are original equipment on many outboard and inboard motors and are excellent replacements for everyday engine maintenance. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Harder than platinum, Iridium plugs came on the market in the mid-2000’s as coil-on-plug systems began to get more popular. We recommend that you consult the owner’s manual and act according to manufacturer’s recommendation on which spark plug to use also don’t downgrade to copper spark plugs if manufacturer has recommended the platinum spark plugs but there is an option to upgrade to double platinum spark plugs. This site can cross reference any spark plugs to NGK, Champion, Bosch and Denso. Copper spark plug’s core is made up of full copper but the center electrode is made of nickel alloy.

In doing this, both spark plugs that attach to that single coil pack spark at the exact same time – the difference is that one is firing on the compression stroke, and one is firing on the exhaust stroke of the sister-cylinder, which is referred to as a “wasted spark”. “As an example, an Autolite copper 105 versus an XP Iridium 105 will have identical ceramic temperatures and the carbon burn off will be the same,” says Reeves. Now a thing has to be noted here which is the diameter of the center electrode, as we have previously said that the larger the diameter of the center electrode the higher voltage it is required to produce a spark.

The metal used to coat the electrodes is how different types of spark plugs are known and defined. So which kind or spark plugs are there in the market? The first factor you have to keep in mind that the spark produce by the spark plugs is between two points. Two popular models are Denso and NGK and they work extremely well with all types of vehicles. These spark plugs are classified into four types due to the material used in their manufacturing. Iridium plugs usually feature the smallest diameter center, which can increase efficiency by reducing voltage needed to create a spark. The copper spark plugs are widely used in old cars which have low voltage distributor based ignition systems and their use in latest cars equipped with high voltage distributor less ignition system (DIS) and coil on plug ignition systems (COP) is non existent. Let's find out. Out of these four types, three are widely used, which are: Now which one should you choose between these spark plugs? Double Platinum Spark Plugs. Common thread (nut) sizes in Europe are 10 mm (16 mm), 14 mm (21 mm; sometimes, 16 mm), and 18 mm (24 mm, sometimes, 21 mm). To counter this quenching U or V shaped channeling is created on the receiving side of the spark so that the spark channeling through the side electrode will allow the flame to grow quickly as well as provide a larger channeling area.

Learn typical price ranges and what can make change that cost. If the diameter of the center electrode is larger it will require more current to generate a spark compared to the center electrode having smaller diameter. Also the running temperature of the platinum plate is higher which is good in terms of preventing carbon buildups overtime. Below is a cross-reference list of spark plugs for use in most Harley models.
