- The letter combination (1-4) before the heat rating indicates the thread diameter, hexagon spanner width and the design.
- The 5th position ( number) stands for the heat rating.
- The 6th letter identifies the thread length.
- The 7th letter contains data about special spark plug construction features.

How do I know which spark plugs I need?
The different types of spark plugs can seem overwhelming at first, but the simple way to find out what kind of spark plug you need is by checking your owner's manual. The manual will specify the right plugs for your vehicle.
What are the different types of NGK spark plugs?
Types of Spark PlugsPlatinum Spark Plugs. ... Spark Plugs with Multiple Ground Electrodes. ... Spark Plugs with V-Groove in the Centre Electrode. ... Spark Plugs with Supplementary Spark Gap. ... Semi-surface Ignition Type Spark Plugs. ... Hybrid Spark Plugs. ... Racing Spark Plugs. ... LPG/CNG Spark Plugs.
How are the spark plugs numbered?
The plug number is used to decode the spark plug and the stock number is used by our sales associates to aid in stock management, as alphanumeric numbers are harder to inventory. The stock number is a random 3-, 4- or 5-digit number and has no relation to heat range or plug type. An example is: DPR5EA-9; 2887.
Which NGK plug is hotter?
On NGK spark plugs, the lower the number the hotter the plug (higher numbers are colder). Thus, your NGK BR9ES is colder than a BR8ES.
Can spark plugs increase horsepower?
When you change your worn-out spark plug with fresh spark plugs, you'll notice a much faster engine response when driving. While spark plugs don't technically increase your engine's horsepower, they bring it back to its optimal combustion level.
What is the life of a spark plug?
A standard copper spark plug has an average life span of 10,000-20,000 miles. Silver plugs, used for older vehicles, can last up to 20,000 miles. Expensive iridium spark plugs or platinum spark plugs can last 60,000 miles. Extended life spark plugs or long life spark plugs can last 100,000 miles.
Is iridium or platinum better?
Iridium is arguably eight times stronger and six times harder than platinum. It has a higher melting point of about 700 degrees compared to platinum. Platinum spark plugs wear out faster than iridium spark plugs. Iridium plugs are said to be more durable compared to platinum plugs up to 25% more.
What does the R mean in NGK plugs?
Resistor[R] Resistor - If an R is present, this indicates a resistor type spark plug. Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio.
What is the difference between NGK Iridium IX and laser Iridium?
These two plugs perform similarly, due to their fine-wire tip design, but the service interval is different; the Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium IX® spark plugs are designed to last 40 to 50 thousand miles.
Are all NGK Spark Plugs iridium?
Iridium spark plugs are globally the best performance category of spark plugs having superior technology. These spark plugs use very precious Iridium metal at the tip of center electrode of diameter 0.6mm....NGK Iridium Spark Plugs.FeaturesBenefitsSpecial thermo edge design for center electrode.– Good anti fouling performance.1 more row•Jul 1, 2020
What is the most important aspect of spark plug installation?
Torque is one of the most critical aspects of spark plug installation. Torque directly affects the ability of the spark plug firing end to dissipate heat to the cylinder head. A spark plug that is under-torqued will not be fully seated in the cylinder head and heat dissipation will be slowed.
How to tighten spark plugs on a car?
Remove the dirt at the gasket seal of the cylinder head. Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench. (Taper seat: About 1/16 turn more.)
What happens if you stretch a spark plug?
Stretching of the spark plug metal shell can break the inner gas seals or cause a fracture in the spark plug insulator. The most dangerous result is pre-ignition when the heat dissipation is reduced due to metal shell stretching by over torquing. In short, over torquing can cause severe engine damage. The spark plug holes must always be clean prior ...
Should you remove spark plugs in a cool engine?
Of course, you should only remove and install spark plugs in a cool engine, because metal expands when hot and thread damage can happen. Proper torque specs for both aluminum and cast-iron cylinder heads are listed below. Spark Plug Type. Thread Diameter. Cast Iron Cylinder Head (lb-ft.)
Do spark plugs need to be cleaned?
The spark plug holes must always be clean prior to installation; otherwise, you may be twisting against dirt or debris and the spark plug will be under-torqued, even though your torque wrench indicates the proper torque.
Can spark plugs overheat?
As a result, the firing end of the spark plug can overheat and pre-ignition can occur. Serious engine damage can follow. Over torque can cause the metal shell of the plug to stretch. The threads can crack and/or break off. Stretching of the spark plug metal shell can break the inner gas seals or cause a fracture in the spark plug insulator.
What is the stock number on NGK spark plugs?
The stock number is a random 3-, 4- or 5-digit number and has no relation to heat range or plug type.
What is the plug number for NGK?
DPR5EA-9 is the plug number and 2887 is the stock number. The exception to this is racing plugs. An example of an NGK racing plug is R5671A-11.
