The Lexus LS500h Valve Stem Seal protects each combustion chamber by stopping the intrusion of oil yet allowing the valve stem to easily glide around in high speed, keeping power crisp and emissions low. Trusted throughout each LS500h production year, this Valve Stem Seal employs a pliant fluororubber lip that hugs the stem, meters a thin oil film, and shrugs off searing temperatures that can reach hundreds of degrees within the cylinder head. Because it ensures no carbon buildup on the valve and prevents spark plug fouling, the Valve Stem Seal maintains the reliability owners of Lexus vehicles come to expect, all while the hybrid V6 and its Multi-Stage system provide torque without smoke or misfires. Drivers experience faster throttle response, a steadier idle, and even better gas mileage thanks to a critical Valve Stem Seal working in tandem with intake and exhaust valves. Durability testing has found that one quality Valve Stem Seal will often last the life of the sedan, limiting service interruptions and adding to the low-maintenance reputation of the LS500h line. Fitment is simple as Lexus kept it with a single specification, which means the same Valve Stem Seal will fit early 2018 sedans to the recent 2023 facelift, including rear-wheel and all-wheel LS500h variants. By keeping the oil out of the combustion chamber, the seal also aids the cleaner functioning of catalytic converters, which make it possible for safety suites such as Lexus Safety System+ 2.0 to operate without the distraction of warning lights being triggered by excess emissions. Owners rave about the build standards of a Lexus, stating that the Valve Stem Seal remains leak-free even after hundreds of thousands of hybrid miles. Its dependable performance allows the LS500h to be whisper-quiet on the highway, and the LS500h continues to set standards, in part due to the Lexus engineered Valve Stem Seal that minimizes friction and heat.
