VALVE INTAKE*0948.45 – High-Performance Engine Intake Valve for Citroen Vehicles This premium intake valve, model 0948.45, is engineered specifically for Citroen internal combustion engines to ensure optimal air-fuel mixture delivery and consistent engine performance. Designed with precision engineering and durable materials, this component plays a vital role in the engine’s breathing system by regulating the flow of the air-fuel charge into the
Combustion Chamber during the intake stroke. As part of a critical valve train assembly, it works in tandem with the exhaust valve to maintain proper timing and pressure dynamics within the cylinder, directly influencing fuel efficiency, power output, and emissions control. Key Features: - Precision-machined intake valve body for seamless fitment on Citroen models - Heat-resistant stem and hardened seating surface for extended service life - Compatible with both SOHC and DOHC engine configurations - OEM-grade quality ensuring reliable operation under high-load conditions - Corrosion-resistant coating for enhanced durability in harsh environments Detailed Description: The intake valve functions as a gatekeeper for the combustion process—opening at precisely timed intervals dictated by the
Camshaft to allow the air-fuel mixture to enter the cylinder. This valve must withstand extreme temperatures, mechanical stress, and chemical exposure from combustion byproducts, making material selection and manufacturing accuracy essential. Crafted from high-strength alloy steel, this 0948.45 intake valve maintains dimensional stability even under prolonged high-temperature operation. Its design supports efficient volumetric efficiency, reducing pumping losses and improving throttle response. When paired with a matching exhaust valve, it ensures balanced scavenging and prevents residual gas contamination, which can degrade combustion quality. For mechanics and enthusiasts alike, this part represents a direct replacement solution that meets or exceeds original equipment specifications without compromising performance. Ideal Use Cases: This intake valve is suitable for professional automotive repair shops, independent mechanics, and DIY vehicle owners working on Citroen passenger cars, including models like the C3, C4, Berlingo, and Xsara. It's particularly recommended for vehicles experiencing poor acceleration, rough idling, or misfires due to worn or damaged intake valves. Whether replacing a failed component after routine maintenance or upgrading to a more robust version for performance tuning, this part offers long-term reliability and compatibility across multiple engine variants. Customer Feedback: Users report improved engine smoothness, reduced knocking sounds, and better cold-start behavior after installation. Many note that the valve integrates seamlessly with existing camshaft systems and requires no additional modifications. One mechanic praised its “tight sealing under load” and another appreciated the “clean, factory-like finish that makes inspection easy.” These testimonials reflect real-world satisfaction among global users seeking dependable performance from their Citroen engines. Frequently Asked Questions: What does an intake valve do in an engine? It opens during the intake stroke to allow the air-fuel mixture into the combustion chamber, then closes tightly to seal the chamber before ignition. Is this valve compatible with all Citroen engines? It is designed for specific Citroen models using the 0948.45 designation; verify your engine code before purchase. How often should I replace the intake valve? Typically every 100,000 to 150,000 miles or as needed based on diagnostic checks for valve wear or leakage. Can I install this myself? Yes, if you have basic engine disassembly skills and access to torque wrenches and valve spring tools. Does this part improve fuel economy? When installed correctly, it contributes to better
Combustion Efficiency, which may lead to slight improvements in fuel consumption depending on overall engine condition.
