VALVE INTAKE 90295011 for OPEL Astra F/G, Kadett E, Corsa A, Ascona C, Vectra A/B – High-Performance Engine Valve Component This high-quality intake valve (Part Number: 90295011) is specifically engineered for a range of OPEL models including the Astra F/G, Kadett E, Corsa A, Ascona C, and Vectra A/B. Designed to optimize engine performance, this component ensures precise control over the air-fuel mixture entering the combustion chamber, directly influencing fuel efficiency, power output, and emissions levels. As a critical element in internal combustion engines, it works in tandem with the exhaust valve to maintain seamless airflow dynamics throughout the engine cycle. Key Features: - Precision-engineered intake valve stem and head geometry for optimal sealing and durability - Manufactured from heat-resistant alloy materials to withstand extreme operating temperatures - Compatible with OEM specifications for reliable fitment across multiple OPEL vehicle platforms - Designed for long-term reliability under high-load conditions such as highway driving or towing - Integrated with camshaft-driven actuation system for synchronized opening and closing timing Detailed Description: The intake valve plays a pivotal role in the four-stroke engine cycle by regulating the flow of the air-fuel charge into the cylinder during the intake stroke. Unlike standard valves, this unit features enhanced surface finish and hardened seating surfaces to reduce wear and prevent premature failure. Its design aligns precisely with the camshaft lobes of your OPEL engine, ensuring accurate timing and minimal valve train noise. By maintaining consistent airflow and minimizing turbulence, this intake valve contributes significantly to improved torque delivery and smoother idle characteristics. It also supports better cold-start performance and reduced hydrocarbon emissions—key factors for modern environmental compliance standards. Whether you're restoring an older model or upgrading worn components, this part offers OEM-level quality at a competitive price point. Use Cases: Ideal for automotive enthusiasts, professional mechanics, and DIY repairers working on mid-1990s to early 2000s OPEL vehicles. Suitable for both routine maintenance and performance tuning applications where increased airflow efficiency is desired. Commonly installed during engine rebuilds, valve job services, or when replacing damaged or carbon-clogged intake valves due to prolonged use or poor fuel quality. Customer Reviews: "Replaced the original valve after noticing rough idling and loss of power—I can now feel the difference in acceleration. Fits perfectly without modification." "Excellent build quality. I’ve used several aftermarket parts before, but this one feels like it came straight from the factory." "Perfect match for my 1997 Opel Astra G. No leaks, no ticking sounds—just smooth operation." Frequently Asked Questions: What makes this intake valve different from generic replacements? It’s manufactured using precision casting techniques and tested for dimensional accuracy, ensuring compatibility with your OPEL engine's valve train system. Unlike low-grade alternatives, it maintains structural integrity even under high thermal stress. Is this valve suitable for daily driven vehicles? Yes, it’s designed for everyday use, offering durability and consistent performance over time. Many users report improved fuel economy and fewer misfires after installation. Can I install it myself? While basic mechanical knowledge is required, we recommend professional assistance if you’re unfamiliar with engine disassembly procedures. Proper torque specifications must be followed to avoid damage to the cylinder head or valve seats.

 

Combustion Excellence, powered by the precise synergy of engine intake and exhaust systems. An optimized Valve Intake System significantly enhances Engine Airflow Optimization, ensuring ideal air-fuel mixture, while an efficient Valve Exhaust System swiftly clears exhaust gases and reduces backpressure. Together, they enable a more complete and cleaner combustion process. This integrated approach not only boosts power output but also substantially reduces emissions, achieving a dual breakthrough in performance and environmental sustainability.
