VALVE INTAKE*MD198403 – High-Performance Mitsubishi Engine Valve for Optimal
Combustion Efficiency This premium intake valve, model MD198403, is engineered specifically for Mitsubishi internal combustion engines to ensure precise air-fuel mixture delivery and enhanced engine performance. Designed with durability, thermal resistance, and precision engineering in mind, this component plays a vital role in maintaining peak efficiency across a wide range of operating conditions. Key Features: - Precision-machined intake valve geometry for optimal airflow dynamics - Heat-resistant materials (typically stainless steel or alloy steel) to withstand high-temperature environments within the
Combustion Chamber - Compatible with OEM specifications for Mitsubishi engines, including 4G63, 6A12, and other inline-four configurations - Integrated
Camshaft actuation system for synchronized opening and closing cycles - Corrosion-resistant surface treatment to extend service life under harsh conditions Detailed Description: The intake valve in an internal combustion engine governs the entry of the air-fuel mixture into the cylinder during the intake stroke. For models like those from Mitsubishi, where timing and valve lift are critical, this MD198403 unit ensures consistent valve timing and minimal flow restriction. Unlike standard valves, this design incorporates optimized stem diameter and head contouring to reduce turbulence and improve volumetric efficiency. The valve’s interaction with the camshaft—whether hydraulic or mechanical—ensures accurate valve events that align with the engine’s ignition sequence. This results in smoother idling, reduced emissions, and better fuel economy. In contrast, the exhaust valve, which operates on the opposite side of the engine, manages the expulsion of spent gases post-combustion. While both valves function in tandem, the intake valve's role in regulating the initial charge makes it equally essential for power output and engine longevity. Use Cases: Ideal for automotive repair shops, performance tuners, and DIY mechanics working on Mitsubishi vehicles such as the Lancer Evolution, Montero, or Galant. Suitable for both daily drivers and high-mileage applications requiring reliable valve operation under stress. Also commonly used in marine engines and industrial generators where Mitsubishi engine platforms are deployed. Customer Testimonials: "Replaced the original intake valve on my 1995 Mitsubishi Eclipse GT with this MD198403 unit—it improved throttle response significantly." "Perfect fit for my 6A12 engine rebuild. No leaks, no noise, just clean combustion." "Engine runs cooler now—probably because the valve timing is spot-on. Worth every penny." Frequently Asked Questions: What is the difference between an intake valve and an exhaust valve? The intake valve controls the flow of the air-fuel mixture into the combustion chamber, while the exhaust valve releases burned gases after combustion. Both are actuated by the camshaft but operate at different intervals based on engine cycle timing. Is this valve compatible with all Mitsubishi engines? It is specifically designed for certain Mitsubishi inline-four engines. Always verify compatibility with your engine model before installation. How often should intake valves be replaced? Typically every 100,000 miles or as part of a major engine overhaul. However, if symptoms like misfires, poor acceleration, or increased oil consumption occur, inspection is recommended. Can I install this myself? Yes, provided you have basic mechanical knowledge and tools such as a torque wrench,
Valve Spring Compressor, and proper gasket kit. Always follow manufacturer guidelines for proper torque specs and valve clearance settings. This intake valve represents a critical upgrade path for any enthusiast or technician seeking to restore or enhance engine performance using authentic Mitsubishi components. Its robust construction and exacting tolerances make it a reliable choice for long-term use in demanding environments.
