PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
- The A7TJC spark plug is specifically designed to cater to the stringent demands of high-performance engines. Its construction, with a 7mm thread length and a heat range classified as 'T', denotes its suitability for engines that require a slightly hotter spark for optimal combustion. The 'J' in the model name refers to the gap configuration, indicating a conventional gap setting that ensures consistent ignition.
