- Another benefit of using iridium spark plugs is their ability to improve cold starting performance. Iridium plugs require less voltage to produce a spark, making them ideal for starting your engine in cold weather conditions. This can help to reduce wear and tear on your engine and battery, as well as decrease the likelihood of stalling or rough idling when starting up.

They are a testament to the intricate interplay between various components in an engine and how even the smallest detail can make a substantial difference. Whether for daily commuting or high-performance racing, investing in quality 7mm spark plug wires is a smart move for any vehicle owner seeking to maximize their engine's potential.
- Low compression
a) The shaft on which the oil seal is to be mounted should be ground with the surface finish or surface roughness between 0.2 to 0.8 Microns. It is best for the shaft to be hardened atleast to 40 – 45 HRc in order to prevent groove formation on the shaft due to the pressure exerted by the spring.
- small amount of amine corrosion inhibitor, it will rapidly age, and therefore has been replaced by
- Maintenance is another critical aspect of spark plug use
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.

Choosing Quality Spark Plugs for Vehicles

ELASTOMER MATERIAL + PTFE – THE PERFECT COMBINATION

An oil seal is a device used to prevent dirt, dust, water, or any other foreign matter from contaminating shafts and bearings in the rotary shaft equipment. Also known as a shaft seal or dirt seal, it also blocks the leakage of lubricants such as grease and oil along a rotating shaft.
2. PRESSURE: Oil Seals cannot endure a lot of pressure. You need to understand your machinery’s pressure capabilities and ensure you use the correct seal to withstand its pressure levels.
