Product Details

The Honda OEM Engine Oil Drain Plug is a genuine factory replacement designed for a wide range of Honda and Acura vehicles, including popular Civic, Accord, CR-V, Fit, Pilot, Odyssey, and S2000 applications. This essential maintenance component secures the engine oil pan drain opening, helping prevent oil leaks while allowing engine oil to be drained during routine oil changes.

Manufactured to Honda's original equipment specifications, this genuine drain plug features a 14mm threaded diameter and 17mm hex head, providing the correct factory dimensions for compatible Honda oil pans.

Over time, the original oil drain plug can become damaged from repeated oil changes, improper tightening, or worn threads. A rounded bolt head, damaged threads, or an improperly sealing drain plug can make oil changes difficult and potentially lead to engine oil leaks.

Replacing a damaged or worn drain plug with a genuine Honda OEM component helps restore proper sealing and ensures compatibility with the factory oil pan.

Whether you're performing routine maintenance on your Honda Civic Si, servicing a K-series engine, or completing an engine rebuild, this genuine Honda oil drain plug provides a reliable factory-quality replacement.

The drain plug washer is typically replaced during each oil change to help maintain a proper seal between the drain plug and oil pan.
Common Reasons to Replace an Oil Drain Plug
A damaged or worn oil drain plug can cause several maintenance-related problems, including:
Rounded or damaged hex head
Stripped or worn threads
Engine oil seepage around the drain opening
Difficulty removing or tightening the drain plug
Damaged sealing surface
Missing or incorrect drain plug hardware
If the oil pan threads are damaged, replacing the drain plug alone may not correct the problem. Inspect the oil pan before installation.

Installation Notes

Before installation, confirm that the replacement drain plug matches the original plug and is compatible with your vehicle's oil pan.
Allow the engine to cool sufficiently before beginning service, and safely support the vehicle if access underneath is required.
Position an appropriate drain pan beneath the engine oil pan and carefully remove the original drain plug.
Inspect the oil pan threads and drain plug sealing surface for damage, contamination, or debris. If the oil pan threads are stripped or damaged, repair may be required before installing the replacement plug.
Install a new 14mm crush washer, Honda part number 94109-14000, when specified for your application.
Thread the new Honda OEM oil drain plug into the oil pan by hand to prevent cross-threading. Once properly seated, tighten it using the torque specification listed in the factory service manual for your specific vehicle.
Do not overtighten the drain plug, as excessive torque can damage the oil pan threads or sealing surface.
After refilling the engine with the correct oil type and quantity, start the engine and inspect the drain plug area for leaks.
Recheck the engine oil level and confirm that the drain plug remains properly sealed.

Note:

Includes one genuine Honda 14mm engine oil drain plug. The crush washer, engine oil, oil filter, and additional maintenance components are sold separately unless otherwise specified.

For Honda and Acura owners performing routine oil changes, maintaining a K-series engine, or replacing damaged oil pan hardware, this genuine Honda OEM Engine Oil Drain Plug provides the correct factory fit and dependable sealing performance needed for proper engine maintenance.
