It is installed between the air box housing and the engine intake to maintain a proper seal, preventing unmetered air, dirt, and moisture from entering the intake tract and disrupting the air\/fuel mixture. A worn, cracked, or compressed air box gasket can cause a rough idle, hesitation, or an inconsistent fuel mixture, so replacing it during routine maintenance or when servicing the air box helps restore a proper seal.\u003c\/p\u003e\u003cp\u003eThis gasket is lightweight at 0.03 pounds and is identified by UPC 030999751102 and Sierra part number 18-0140. It is intended as a direct-fit replacement for the factory air box gasket on applicable Evinrude outboard engines, making it a straightforward maintenance item to keep on hand for outboard servicing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-0140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Air Box Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Evinrude Outboard Engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999751102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits applicable Evinrude outboard engines.
