What is the function of a spark plug?
In simple terms, the spark plug ignites the compressed fuel-air mixture, producing the combustion that powers gasoline engines. The spark plug converts electrical energy from the battery which comes through the ignition coil and distributor into a spark which ignites the fuel-air mixture. The spark plug has to continuously produce good sparks from the starting and throughout the running of the engine, and thus it is one of the most critical components of the engine. The spark plug is an important factor in determining optimum performance and reliable functioning of an engine as the engine wouldn’t run without it. It must permit reliable cold starting, it must guarantee that there is no misfiring during acceleration, and it must withstand the engine being operated for hours on end at maximum power. These requirements apply throughout the entire service life of the spark plug.

What are the most important parts of a spark plug?
The terminal stud, insulator, shell and electrodes (center and ground) represent the most important parts of a spark plug, and are vital to a spark plug’s performance and life span. 1 Terminal Stud The steel terminal stud is melted, gas-tight, into the insulator with a special conductive glass seal that also serves as the electrical connection to the center electrode. A terminal nut is also attached, which connects to a spark plug wire of ignition coil.
the spark plug shell has an electroplated nickel coating to prevent corrosion, to keep the thread free and to prevent seizing. After the insulator has been inserted into the spark plug shell, it is crimped and heat-shrunk into position. 4 Electrodes
Electrodes (ground and center) must have good heatdissipation properties and must also be resistant to wear, in order to maintain the required ignition voltage over the service life of the spark plug. a) Center Electrode The center electrode projects from the insulator nose. It is melted, gas¬tight, into the insulator with a special conductive seal. The center electrode can be made of many different materials. Center electrodes made of precious metals such as platinum (Bosch Platinum Series) or fused iridium and platinum (Bosch Platinum-Iridium Fusion) are smaller in diameter than the compound electrodes that have a copper core and yttrium-enhanced nickelalloy jacket (Bosch Super Plus). b) Ground Electrode Different Spark Plugs Features: • Different numbers of ground electrodes • Ground electrodes of varying dimensions • Different ground electrode materials (e.g. yttrium) The ground electrode(s) are welded to the shell and usually have a rectangular cross-section. The ground electrode’s service life is highly dependent upon its ability to dissipate heat. In the ground and center electrodes, suitable composite materials are employed to improve thermal dissipation and extend service life. Thicker ground electrodes and multiple electrodes can both be used to extend spark plug service life. Terminal Nut

As spark plugs are consumable items, periodical replacement is required. Since the spark plug works continuously during the engine operation, it is necessary to change them even if the correct spark plug is used. The life of the spark plug depends on the type of spark plug used and the engine condition. If the spark plug is not changed as by the requirement, it can hamper the proper functioning of the engine (refer Q 11). Replacing spark plugs improves engine’s performance, life of the engine and fuel efficiency.

Is it true that I should only install the original equipment brand plug, because they run better than replacement spark plugs of other brands?
No! Bosch Spark Plugs can be used with confidence to replace other brands' OE plugs. Although Bosch Spark Plugs may not be original equipment (OE) in a particular application, be assured that Bosch manufactures all spark plugs to meet or exceed OE specifications whether it's for a car or 2 wheeler. Our goal is to deliver the highest quality product to the consumer.
26902-Bosch Cross Reference Plug@FA.indd 8-9
9 How do I install spark plugs?
• Allow engine to cool • Disconnect cables or ignition coils. Mark spark plug cables/ coils to ensure replacement in proper sequence • Loosen plugs one or two turns and clean surrounding area so that no dirt particles get into the threads or the combustion chamber • Remove worn spark plugs. If the spark plug is extremely tight, loosen only a little to allow penetrating oil to drip onto exposed thread, screw the plug in again and attempt to remove it after a few minutes • Check gap of new Bosch Spark Plugs and adjust if necessary. (Important: Do not gap Platinum-Iridium Fusion) • Thread in Bosch Spark Plug until hand tight. Use a torque wrench and suitable spark plug socket, tighten the spark plug to the manufacturers recommended torque. If torque wrench is not available, follow the procedure below. • Replace spark plug wires or coil boots if equipped Spark Plug Gapping Bosch Platinum-Iridium Fusion Spark Plugs come with gaps pre-set at the factory. These gaps are never to be adjusted. Bosch Platinum Plus and Super Plus Spark Plugs also have factory-set gaps. For most plugs, the setting is shown on the plug package. These gaps are correct for the most popular applications of these plugs. There are applications, however, for which the gap setting has to be adjusted according to the vehicle manufacturer's specifications. To avoid damage to a spark plug in the process of adjusting the gap, it is important to follow these guidelines: • To widen the electrode gap, use a tool that only pulls back the ground electrode, without applying pressure to the center electrode (see illustration 1). The tool must not be wedged between the electrodes as that may cause damage to the insulator nose. • To close the electrode gap, carefully tap the plug, electrode first, on a hard surface, as shown in illustration 2.
10 Is there a specific tightening torque to be used for the spark plug?
12 What are the effects of spark plug fouling?
Bosch recommends when installing spark plugs to use a torque wrench and the correct torque in Nm. listed below. As a general guideline, if a torque wrench is not available, hand tighten the plug until it is seated in the cylinder head. Spark plugs with gaskets should be tightened an additional 90°. Spark plugs with tapered seats should be tightened an additional 15°.*
The following are the pictures of used spark plugs subjected to various causes of fouling:
Normal
Carbon Deposit
Oil Fouled
Severe Lead Deposit
Ash Deposits
Partially Melted Center Electrode
Partially Melted Electrodes
Center Electrode Erosion
Ground Electrode Erosion

Insulator Nose Breakage
*Note: Avoid overtightening or undertightening as spark plug or engine damage may result. Always follow the manufacturer recommended torque specifications.
Failure to sufficiently seat the plug in the engine spark plug seat, or overtightening the plug, will likely result in one or more of the following:
13 What is the heat range of a spark plug and why is it important?

Bosch Spark Plug - FAQ | 9
A plug's heat range is its ability to transfer the excess heat from the insulator tip to the cylinder head. The speed of this transfer is commonly described by the term "hot plug" and "cold plug," A "hot plug" means that the heat transfer is slow, causing the plug to operate at a higher temperature. A "cold plug" has a faster rate of heat transfer, thus it operates at a cooler temperature. In other words, a "hot" plug has a high heat range, a "cold" plug has a low heat range. Plugs are available in different heat ranges to accommodate the operating conditions of different engines and driving conditions. A plug must operate hot enough to stay clean (not foul) and cold enough to prevent pre-ignition (premature ignition of the fuel-air mixture). If pre-ignition were not controlled, engine performance would drop and the plug would eventually destroy itself by overheating. The heat range is determined, for the most part, by the insulator material, the length of the insulator tip, and the alloy material of the center electrode. The amount of heat transfer is affected by the size and shape of the space between the insulator and plug shell and by the quality of insulator material. A positive contact between the insulator and shell must be provided. Figures 1, 2 & 3 show these differences.
14 Can Bosch Spark Plugs be used in gas (CNG/LPG) engines? Yes! you can use Bosch spark plugs specified for gas engines. Due to differences in technology between petrol and gas engines, only the right spark plug guarantees faultfree operation. Bosch Spark Plugs combine impressive reliability and a long service life. To get maximum advantage from gas conversion, spark plugs have to be changed: • Spark plugs with lower heat value have to be used to counter the higher temperatures in the combustion chamber • The spark plug gap has to be reduced because of the higher ignition voltage required • Spark plugs with better wear resistance are needed in such harsh conditions
Gas requires a higher ignition voltage than petrol Higher iginition voltage and higher temperature in combustion chamber leads to faster wear of electrodes
Flexibility of compensating for the voltage Easy installation increase by gap reduction Spark plugs with Yttrium* Longer service life and Platinum of gas spark plugs will increase wear resistance
* Yttrium is a rare earth element added to nickel. It will increase the wear resistance properties of the spark plug (Service life of Yttrium plugs is 50% higher compared with normal plugs). The Bosch Spark Plug range offers the right components for vehicles running on gas, ensuring the reliability, performance and long service life of the engine.
