Toyota part number 17171-17030 is a genuine OEM intake manifold gasket engineered to provide an airtight seal for the intake system. In turbo diesel engines, a precise and reliable seal is essential for maintaining boost pressure, ensuring optimal air-fuel mixture formation, and delivering consistent engine performance.

Technical Specifications:

• Manufacturer: Toyota (Genuine OEM part)
• Part Type: Intake manifold gasket (Gasket, intake to exhaust manifold)
• Material: High-temperature and mechanically resistant composite/metal sealing material
• Outstanding dimensional stability and gas tightness under boost pressure

Vehicle Compatibility:

• Toyota Coaster (B40/B50) 4.2 TD [1999 - 2004] (GASKET, INTAKE TO EXHAUST MANIFOLD (1HDFT))
• Toyota Land Cruiser 100 (J100) 4.2 TD [1998 - ...] (GASKET, INTAKE TO EXHAUST MANIFOLD (HDJ100, 1HDFTE))

Significance and Symptoms of Wear:

Aging, cracking, or blowout of the gasket results in a loss of gas tightness, causing a direct drop in engine performance. Typical signs of failure include a hissing or blowing noise from the engine bay during acceleration, reduced boost pressure, increased exhaust smoke and fuel consumption, and visible oily or sooty deposits around the intake manifold mating surfaces.
