MCS Oil Drain Plugs

10 products — part of all Oil Drain Plugs

MCS oil drain plugs for Harley-Davidson cover the engine, primary and transmission oil systems with quality replacement and upgraded drain hardware that ensures a leak-free seal through every service interval. A correctly fitting drain plug is the foundation of a clean, reliable oil system — undersized or damaged threads allow oil to seep at low pressure and worsen rapidly with heat cycling. MCS supplies drain plugs in the thread specifications used across Harley-Davidson's V-twin engine range, including magnetic variants that capture metallic wear debris between services as an early indicator of internal wear. Replacing drain plugs at regular intervals is simple preventive maintenance that pays dividends in engine cleanliness and longevity. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks the full MCS oil drain plug programme. Browse the full MCS Oil Drain Plugs range below.
