Toyota 15643-31050 Genuine Oil Filter Drain Plug — for V6 and V8 Engines

Oil leaks from the oil filter housing, a stripped or damaged drain plug, or difficulty removing the plug during an oil change — these are common signs that your oil filter drain plug needs replacement. The drain plug is a small but critical component that seals the oil filter housing, allowing you to drain the oil from the filter before replacement. A faulty or damaged plug can cause oil leaks, loss of oil pressure, and potential engine damage. Replacing it with this genuine Toyota plug restores a proper seal and ensures leak-free operation.

This is a factory-original Toyota oil filter drain plug (OE part number 15643-31050), designed for oil filter housings on Toyota and Lexus V6 and V8 engines. It features a precision-threaded metal body with an integrated O-ring seal to provide a secure, leak-tight fit. The plug is easy to install and remove with a standard wrench. This is the same part sold at Toyota dealerships.

FAQ

FAQ

Is this a genuine Toyota part or a copy?
This is 100% genuine Toyota OEM — in original factory packaging with Toyota part number printed on the label. It is not an aftermarket brand or a replica.

Does this fit my 2012 Toyota Tundra with the 5.7L V8 engine?
Yes — the 2012 Tundra with the 3UR-FE 5.7L V8 uses this drain plug. We recommend verifying with your VIN.

Does this fit my 2016 Toyota Highlander with the 3.5L V6 engine?
Yes — the 2016 Highlander with the 2GR-FE 3.5L V6 uses this drain plug. Please verify with your VIN.

Does this plug come with a new O-ring?
Yes — the O-ring is pre-installed on the plug. Always use the new plug with the new O-ring — do not reuse the old O-ring.

What is the torque spec for this plug?
The typical torque specification is 25–30 Nm. Always refer to your vehicle's service manual for the exact specification.

Can I reuse this plug?
Yes — you can reuse the plug if it is in good condition. However, you must replace the O-ring each time you remove the plug. The O-ring is not available separately, so you will need to purchase a new plug to get a new O-ring.

Is this the same as the oil pan drain plug?
No — the oil pan drain plug is a different part with a different size and thread. This plug is specifically for the oil filter housing.

Does this fit my Lexus RX with the 2GR-FE engine?
Yes — the Lexus RX with the 2GR-FE 3.5L V6 uses this drain plug. Please verify with your VIN.

Will this plug work with aftermarket oil filter housings?
This plug is designed for the factory Toyota oil filter housing. Aftermarket housings may use a different thread size.

How do I install this plug?
Install the plug by hand until it seats, then tighten with a wrench to the specified torque. Do not overtighten — this can strip the threads or damage the O-ring.

What if my plug is stuck?
Use a penetrating oil and allow it to sit for a few minutes before attempting removal. Always use the correct size wrench.
