Spare Plugs and Glow Plugs
Spark plugs and glow plugs work so your ignition is always reliable and ready to respond.
Spark plugs work differently depending on the fuel: in petrol engines they begin the combustion stage, creating the spark that ignites the air-fuel mixture; in Diesel engines they work with self-ignition. The fuel is injected and ignites when the air-fuel mixture reaches self-ignition temperature.
For a reliable and efficient ignition
TO EACH ENGINE ITS OWN SPARK
Able to work under extreme conditions
High tolerance to stress and high pressures
Control of high temperature variations
Prevention of chemical corrosion
Designed and created to tolerate temperatures that range from ambient up to 2,000°C – 2,500°C and the chemical corrosion by fuel and unburned gases, our spark plugs are self-cleaning because they completely burn soot deposits.
Remember that every engine requires a specific spark plug, as combustion temperatures vary from model to model and, for each of them, there is a spark plug with a compatible heat rating.
THEY GIVE YOU
- Reduction in fuel consumption and emissions
- Increased performance at any speed
- High ride comfort
- Engine flexibility
NATURAL POWER SPARK PLUGS
For those who choose cars powered by gas
WHETHER LPG OR METHANE, CHOOSE EFFICIENCY
Increased tolerance to the high temperatures of gas combustion
Lower voltage required
You are one of the many who chose gas power, it’s important for you to know that combustion with a gaseous mixture is considerably different from an air-fuel one.
The voltage and combustion temperature, in fact, are much higher and lead to increased erosion of the spark plugs.
This is why it’s important to always choose original spare parts: our Natural Power spark plugs are designed to ensure top efficiency during ignition and reliable start performance, even under extreme conditions.
THEY GIVE YOU
- Increased ignition capacity
- Top level performance thanks to a carefully researched distance between the electrodes
So your Diesel has top ignition conditions
A SAFE START WITH NO SURPRISES
High ability to preheat air for combustion
High self-ignition performance
Your Diesel car works using the self-ignition mechanism. This means that the ignition is not triggered by a spark; instead, the diesel is burned by the air it comes into contact with heating up.
In this process, our glow plugs must set the proper thermal conditions to achieve the spontaneous combustion of the air-fuel mixture.
Check often and, if necessary, replace with original spare parts; this is important to always have exceptional ignition performance.
THEY GIVE YOU
- Reliable starts, even when cold
DID YOU KNOW THAT …?
The gas mixture ignites less easily than the petrol mixture
A spark doesn’t always start a fire
The combustion of the gas mixture is more chemically stable than the air-fuel one. Which is why you need ignition spark plugs with special features. In fact, without sparks, you need more energy and a higher firing voltage, and combustion takes place at higher temperatures. The Natural Power spark plugs were designed to withstand this stress, ignition after ignition, with special nickel coatings for the metal body and a platinum ground electrode.
By looking at the spark plugs, you can learn a lot about your car
A healthy appearance is a sign of inner wellness
If you look at the tip of the spark plug insulator you can find out how healthy your car is. A light hazelnut colour, with a few traces of deposit, tells you that the engine is in good condition. Ash deposits on the electrodes, instead, tell you that you used a poor quality fuel, or are a symptom of excessive oil consumption, or that the engine is in subpar conditions. Remember to have the status of your spark plugs checked often, and to replace them, especially when there are deposits that may cause pre-ignition to occur.
If the spark plugs are always in shape, your engine is healthier
A spark plug does not live forever
Spark plugs carry out a challenging task and are subject to wear, even when they’re made with the best materials and technologies. Which is why we recommend replacing them regularly, as specified in your car’s User and Maintenance Handbook. Otherwise, you could come across issues with the combustion, pre-ignition, damaged pistons, all the way to melted electrodes, misfiring or a damaged catalytic converter. Checking often means taking care of the health and wellbeing of your engine.
There’s a lot of work that goes on behind a cold start
A warm heart, even when it’s freezing outside
In addition to air compression, ignition starts in Diesel cars with the help of the glow plugs, located in the cylinder head. Capable of reaching over 1000°C, they heat the air in the combustion chamber, beginning the preheating process that precedes the actual start. Reliable and functioning glow plugs offer crucial support for every cold start, ensuring a rapid start and an environmentally friendly combustion, even at sub-zero temperatures.
