Rein 278-090-49-82 Air Intake Hose

The Rein 278-090-49-82 is a direct-fit air intake hose engineered to OEM specifications for European vehicles. Rein Automotive is a trusted manufacturer of premium rubber and plastic components, delivering factory-quality fit, form, and function without the dealership price tag.

This air intake hose connects critical components of the engine's air induction system, routing fresh air from the air filter housing to the throttle body or turbocharger inlet. A cracked, collapsed, or deteriorated intake hose can cause unmetered air leaks, leading to rough idle, poor fuel economy, reduced power, and fault codes related to mass airflow or boost pressure.

Key Features:

• Manufactured to OEM specifications for precise, rattle-free fitment
• Constructed from high-quality, heat- and oil-resistant rubber or reinforced polymer
• Maintains proper airflow and boost integrity under demanding engine conditions
• Direct replacement — no cutting, trimming, or modification required
• Cross-references to OEM part number 278-090-49-82

Replacing a worn or damaged air intake hose with a quality Rein part helps restore proper engine breathing, protects sensitive sensors, and supports optimal performance and fuel efficiency.
