Product Details

✓Check the size before you order. This is the 20 mm washer for the EJ and EZ boxer engines. Subaru FB and FA engines take the 16 mm washer instead, part number 803916010, and that is a separate AUTOMAJOR listing. The two look alike in a photo and are six millimetres apart in the hand, so put the old washer on a ruler rather than going by the model name on the car or by how it looks on screen.

✓Fits Subaru Baja 2003-2006, Forester 1998-2013, Impreza 1993-2010, WRX 2002-2014 and 2019, WRX STI 2004-2021, Legacy 1990-2013, Outback 1996-2013, Tribeca and B9 Tribeca 2006-2014, SVX 1995-1997, Justy 1988-1994, Loyale 1990-1994, XT 1985-1991, and the GL, GL-10, DL, RS, RX, Brat and Standard of 1985-1989. Later years of some of those models carry conditions on engine and trim, and they are set out in the next line.

✓Two conditions are worth more attention than the rest of the list. Impreza 2011-2014 takes this washer only in WRX and STI form. Legacy and Outback 2014-2019 take it only as the 3.6R with the 3.6 litre six cylinder engine — the 2.5 and 2.4 four cylinder cars of those same years run the 16 mm washer. That one detail sits behind most of the wrong orders on this part, so check the engine badge on the tailgate before ordering.

✓Fifteen washers in steel, 20 mm inner by 26 mm outer by 2.2 mm thick, which is 0.79 in by 1.02 in by 0.087 in. Replaces Subaru 11126-AA001 and 11126-AA000, and the number those superseded, 311680100. Crosses to 095142, 705050, 19159, 18001800 and DDP65511. Fifteen covers fifteen oil services, which on a car serviced twice a year is most of the time anyone keeps it, and the spares cost less than one trip to the parts counter.

✓Every washer is single use. One that has been crushed sits lower the second time and no longer fills the same marks on the pan face, which is where a weep a week after an oil change usually comes from. Torque the drain plug to roughly 41.7 Nm or 30.8 lb-ft on the four cylinder engines and 44 Nm or 32.5 lb-ft on the 3.6 six. Check the manual for the figure that applies to your car.
