Faster and cleaner oil changes with Fumoto’s quick engine oil drain valve

Fumoto’s engine oil drain valve is the best way to change your 2015-2020 STI’s oil. After a short and simple installation, you’ll be able to quickly drain your oil without any mess or tools. Simply lift a lever and give it a turn to open and operate the valve. You’ll see that the solid brass ball valve design creates a straight flow. Once you’re done the valve locks with a double seal to prevent any leakage. It’s made of forged brass and stainless steel to help prevent corrosion. This valve is a must-have if you want to do it yourself and stop getting your threads stripped at the shop!

Note:This is the short nipple version. It allows you to have great ground clearance and still connect a hose for precise draining if desired. M20xP1.5 fits the 2015-2020 Subaru WRX STI.

Endorsed by leading motor vehicle manufacturers in Japan

The Engine Oil Drain Valve has been tested and granted "Genuine Parts" status by 6 major motor vehicle manufacturers in Japan, including Toyota, Nissan, Mazda, Mitsubishi, Subaru and Isuzu. These approvals were not granted easily and gaining them was a testimony to the quality and durability of Engine Oil Drain Valve. We also really like this valve here at Subispeed!

High quality and simple to install on your STI

Remove original drain plug and drain oil into acceptable receptacle. Insert Engine Oil Drain Valve with gasket and tighten. Do not over tighten. (Some oil pans are designed with recessed drain hole which may prevent the valve from being installed properly. If the valve cannot be tightened all the way without hitting the oil pan wall, do not install the Drain Valve to your vehicle. Adapters are available for some models.) Make sure valve is closed and refill crankcase.

Note: It is highly recommended that you use an open 3/4" or 19mm wrench when installing and torquing the drain valve down.

Easy to operate and do it yourself

To open lift control lever and turn counter-clockwise 90 degrees. To close simply turn the lever clockwise 90 degrees until locked in original position. Install the small lever clip once fully closed for added security and protection.


Drive carefully at all times, and if you run over any foreign object on the road pull over and check the valve for any damage or leak.

    Was really easy to install, I was very skeptical of the gasket it comes with but it seems to be holding up quite well with no leaks. It made my oil change really quick and easy.
