- Finally, the installation of LS1 spark plugs is a relatively straightforward process that can be performed by most DIY enthusiasts. However, it's important to choose the right type and size of spark plug to ensure optimal performance and longevity. With the right tools and knowledge, anyone can install these high-performance spark plugs and enjoy the benefits they offer.
- Despite their compact size, oil seal rubber parts have a significant impact on overall system performance and safety. Regular inspection and timely replacement of worn-out seals can prevent major machinery breakdowns, saving substantial costs associated with repair and downtime.
- 'SS' in the CR6HSAA spark plug signifies a single ground electrode configuration
cr6hsa spark plug. This design provides a focused spark, enhancing ignition stability and fuel economy. The 'A' following it represents the heat range, suggesting that this spark plug operates in a slightly cooler temperature range, preventing pre-ignition and ensuring stable performance under high RPM conditions.

Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.
