⑥ - Moreover, the BR7EF spark plug's superior insulation material withstands high temperatures and pressures within the combustion chamber, reducing the risk of misfires
- Secondly, OEM spark plugs contribute to improved fuel efficiency
oem spark plugs. By ensuring a more complete combustion of the air-fuel mixture, these spark plugs help reduce the amount of fuel needed to achieve the desired level of performance. This not only saves money at the pump but also helps to reduce harmful emissions.
- Both the PTFE sealing lip and the shaft surface must be completely dry. Do not use grease or oil. If grease or oil is used, the retaining ring will fail after assembly.
- Petrol Engine Spark Plugs Crucial for Optimal Performance
Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.


Quality assurance and compliance with industry standards are paramount in oil seal manufacturing. Leading companies in the sector adhere to stringent quality control measures to ensure that their products meet or exceed industry specifications. Compliance with regulatory requirements and industry standards is essential to provide customers with reliable and high-performance sealing solutions for their specific applications.
Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
Smear gasket sealant on the mating faces of the pump and the engine. Refit the pump and gasket or gaskets and tighten the fixings.
Wipe the head and block absolutely clean with a cloth moistened with petrol.
