VALVE INTAKE 20758481 – High-Performance Engine Valve for Optimal
Combustion Efficiency This precision-engineered intake valve (part number 20758481) is a vital component in internal combustion engines, particularly designed for Volvo models where reliable air-fuel mixture control is essential. As one of the two primary valves in the engine’s valvetrain system—alongside the exhaust valve—it ensures efficient airflow into the
Combustion Chamber during the intake stroke and maintains optimal pressure dynamics for consistent engine performance. Key Features: - Precision-machined from high-strength alloy steel for durability under extreme thermal conditions - Designed to match OEM specifications for seamless integration with Volvo
Camshaft systems - Enhanced surface finish reduces friction and wear, extending service life - Compatible with both naturally aspirated and turbocharged engines for broad application range - Manufactured using advanced heat treatment processes to resist warping and deformation Detailed Description: The intake valve plays a critical role in the four-stroke cycle by opening at precisely timed intervals to allow the air-fuel mixture into the cylinder. This process directly impacts engine torque, fuel economy, and emissions output. Unlike standard valves, this model incorporates optimized stem geometry and seat angles that improve sealing integrity and reduce leakage, which is especially important in modern high-compression engines. It works in tandem with the exhaust valve—another essential part of the valvetrain—to manage gas exchange efficiently. Together, these components ensure clean combustion cycles, minimize carbon buildup, and support long-term engine health. Whether you're maintaining a vintage Volvo or upgrading a performance vehicle, this intake valve delivers reliability comparable to original equipment manufacturer parts. Ideal Applications: - Used in various Volvo engine platforms including B-series and D-series engines - Suitable for automotive repair shops, DIY mechanics, and fleet maintenance professionals - Commonly replaced in vehicles experiencing misfires, reduced power, or poor fuel efficiency due to worn or damaged intake valves - Recommended for use in passenger cars, light-duty trucks, and commercial vehicles requiring consistent engine responsiveness Customer Feedback: "Installed this valve on my 2006 Volvo S40, and the engine runs smoother than ever. No more hesitation on acceleration." — Michael T., UK "This part feels like it was made to fit perfectly—no modifications needed. A solid upgrade over the cheap aftermarket options I tried before." — Sarah L., Germany Frequently Asked Questions: What is the difference between an intake valve and an exhaust valve? While both are controlled by the camshaft, the intake valve allows fresh air-fuel mixture into the combustion chamber, whereas the exhaust valve releases spent gases after ignition. They operate at different timing points within the engine cycle to maintain proper airflow and pressure balance. Is this valve compatible with all Volvo engines? It is specifically engineered for Volvo models using the 20758481 intake valve configuration. Always verify compatibility with your engine’s make, model, and year before installation. How often should intake valves be replaced? Typical service intervals range from 100,000 to 150,000 miles depending on driving conditions and maintenance practices. Signs of failure include rough idling, decreased fuel economy, or engine knocking—indicating potential valve wear or leakage. Why choose this intake valve over generic alternatives? This unit offers superior metallurgy, precise tolerances, and strict adherence to OEM standards. It’s built for longevity, performance consistency, and reduced risk of premature failure compared to lower-grade replacements.
