Womala Auto Level Indicating Pipe OE 31437020 Transmission drain plug for Volvo S60

Core Functions

• Airtight Sealing for Intake System: Creates a secure seal at intake pipe connection points, preventing unfiltered air (from the engine bay) from bypassing the air filter and entering the intake manifold. Unfiltered air contains dust, debris, or oil vapor, which can damage engine components (like cylinders, pistons) and disrupt the air - fuel ratio. This gasket ensures only clean, filtered air flows into the engine.
• Preservation of Engine Performance & Fuel Efficiency: By maintaining the correct air - fuel mixture (critical for combustion), it supports stable engine power output, smooth idling, and optimal fuel efficiency. A damaged or leaking gasket causes lean fuel conditions (too much air), leading to reduced power, rough running, or increased fuel consumption.
• Resistance to Under - Hood Wear: Withstands under - hood stresses such as continuous vibration (from engine operation), temperature cycles (cold starts to hot operation), and exposure to oil or coolant splashes. Its durable rubber material ensures long - term sealing reliability, reducing the need for frequent replacements and protecting the intake system from premature wear.
