VALVE EXHAUST*1320257Y00 for Nissan – High-Performance Engine Valve Assembly for Optimal
Combustion Efficiency This precision-engineered valve exhaust component, model number 1320257Y00, is specifically designed for Nissan vehicles to ensure seamless airflow management within the internal combustion engine. As a critical part of the engine's valvetrain system, it works in tandem with the intake valve to regulate the flow of air-fuel mixture into the
Combustion Chamber and the expulsion of spent gases post-combustion. Whether you're maintaining a classic Nissan sedan or optimizing a performance-oriented model, this OEM-grade exhaust valve delivers reliable function and long-term durability. Key Features: - Precision-machined from high-strength alloy steel for resistance to thermal stress and wear - Designed for exact fitment with Nissan engine models requiring part number 1320257Y00 - Compatible with both SOHC and DOHC configurations found in many Nissan engines - Ensures consistent valve timing through robust
Camshaft actuation - Reduces emissions by promoting complete combustion and efficient gas exchange Detailed Description: The valve exhaust mechanism plays an indispensable role in engine performance by opening at precisely timed intervals during the engine cycle—specifically during the exhaust stroke—to release burned gases from the cylinder. This process clears the combustion chamber for the next cycle, enabling optimal air-fuel mixing and maximizing power output. Unlike generic replacements, this valve is manufactured using advanced metallurgy and strict quality control standards to match original equipment specifications. Its surface finish minimizes friction against the valve seat, while its heat-resistant coating withstands extreme operating temperatures common in modern automotive environments. When paired with a properly functioning intake valve, it contributes significantly to fuel economy, engine responsiveness, and overall drivability. Ideal Use Cases: This component is essential for mechanics, auto enthusiasts, and vehicle owners performing routine maintenance or engine rebuilds on Nissan models such as the Altima, Sentra, Maxima, or Rogue. It’s particularly valuable for those seeking to restore peak engine efficiency after extended use or mechanical failure. Whether replacing worn-out parts or upgrading for enhanced performance, this valve ensures that your Nissan engine maintains precise valve timing and consistent airflow dynamics. Customer Testimonials: "Replaced the old exhaust valve on my 2012 Nissan Altima, and the engine runs smoother than ever. No more hesitation during acceleration." "I’ve used several aftermarket valves before, but this one feels like OEM quality—tight seal, no leaks, and quiet operation." "Perfect fit for my Nissan Juke. The installation was straightforward, and I noticed better fuel efficiency right away." Frequently Asked Questions: What is the difference between an intake valve and an exhaust valve? The intake valve allows the air-fuel mixture to enter the combustion chamber during the intake stroke, while the exhaust valve opens during the exhaust stroke to release combustion byproducts. Both are synchronized via the camshaft to maintain engine timing accuracy. Is this valve compatible with all Nissan engines? It is specifically designed for Nissan models that require part number 1320257Y00. Always verify compatibility with your vehicle’s make, model, and engine code before installation. How often should I replace the exhaust valve? Typical service intervals range from 80,000 to 120,000 miles, depending on driving conditions and maintenance practices. Inspect for signs of warping, carbon buildup, or leakage during routine engine servicing. Can this be installed without professional help? While possible for experienced DIYers, proper torque specification and valve clearance adjustment are crucial. For best results, consult a certified technician familiar with Nissan engine architecture.
