Spark plugs with the same thread diameter can still differ in reach, heat range, seat style, terminal type, resistor specification, projected-tip design, and required gap. Installing the wrong plug can cause hard starting, misfire, poor idle, overheating, thread damage, piston contact, or ignition-system issues.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eReplace spark plugs during scheduled tune-up service or whenever the plug is worn, fouled, fuel-soaked, oil-contaminated, corroded, cracked, damaged, or causing hard starting, rough idle, hesitation, misfire, weak acceleration, or poor low-speed running. Small four-stroke outboards that idle, troll, or operate in damp and salt-air environments should have plugs inspected regularly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCheck the plug number and required gap against the engine service chart before installation. Install into clean, undamaged cylinder head threads and tighten to the manufacturer's torque specification for the exact engine. Because this is a gasket-seat plug, confirm the sealing washer is present and seats correctly. Avoid adding anti-seize unless the engine or spark plug manufacturer specifically calls for it, as lubricant can change clamping load and increase the risk of over-tightening in aluminum cylinder heads.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK DCPR6E\u003c\/strong\u003e — spark plug part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK 3481\u003c\/strong\u003e — NGK stock number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDCPR6E Standard\u003c\/strong\u003e — product style reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDCPR6E 3481\u003c\/strong\u003e — common catalog reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eDCPR6E\u003c\/strong\u003e is a 12 mm, long-reach, gasket-seat resistor plug. It is commonly used in compact four-stroke marine and powersports engines, but it should not be substituted by thread size alone. Matching the exact plug number, gap, seat style, and heat range to the engine's service chart helps prevent misfire, thread damage, and incorrect combustion-chamber reach.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564191121444,"sku":"NGK-DCPR6E","price":14.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/943826dd-57eb-4261-aab0-15950fe378cd.png?v=1781202584","url":"https:\/\/marisolmarine.com\/products\/west-1141","provider":"Marisol Marine Company","version":"1.0","type":"link"}
