Correct replacement for Subaru Outback
921772
I used the 197-6040 to replace the mass flow sensor in a 2006 Subaru Outback with the 4 cylinder engine and an automatic transmission. This unit was physically an exact replacement for the original unit on the car. I chose this unit due to postings of others that stated that this was the correct unit to use despite contrary recommendations by Amazon and by Denso. The unit IS specified as the correct replacement unit for a number of different Subaru models of the same era including some that used the same engine that is in the Outback. Almost all of these other models came from the factory using exactly the same Mass Air Flow Sensor that was original equipment in the Outback.

These worked perfectly to replace my very old Outback cabin filters.  This is NOT a "quickie" task, however, and don't try to do it unless you have some expert advice.

I found mine on a video on YouTube -

Title is "DIY: Subaru Legacy/Outback/Baja Cabin Filter Replacement"  Excellent video with detailed directions.  Took me about 30-40 minutes in all --being very patient and double-checking along the way.

Box came a bit smashed but they're cheap and easy to replace, especially needed with that heat right there! Fit my 2000 Subaru Outback perfect!

Super easy to install. The instructions were wrong for a 2003 Subaru Outback though. We used this video to help us - [...] find the connection.

Installation was very simple. Works perfect for my 2015 Subaru Outback.

Works perfectly fine with my 2012 Subaru Outback. You just can't go wrong with a Bosch Wiper Blade. Probably the best on the market!

Perfect fit for my 2007 Subaru Outback, bought one for each side of the car. Much easier than trying to press the old bushings out of the stock one.

Fit my 07 Outback and likely any 4th gen Subaru.  I was able to use the over the joint method with no need for an alignment.  I did not use the supplied retainers though the larger one is the same as stock and seems plenty sturdy.  Could have used a grease pack in the box though.

I recently ordered this tail light and installed it today.  It fit my 2003 Subaru Outback Wagon perfectly, is working correctly, and looks good.  Because of Subaru's design the tail light is very easy to install by yourself.

I was (mostly) easily able to install this hitch on my 2017 Subaru Outback. It took a bit of work to cut into the underside for the bolts, but it looks good and has worked well. The Outback has a lower towing capacity than this hitch, and I've maxed that out twice now without fail. So far so good! Don't forget to add a trailer light hookup!

Works great for 2017 Subaru outback. Very happy and will buy again

Perfect fit for my wife's 2002 Subaru Forester. She'd been plagued by a constantly on check engine light that our old tyme mechanic couldn't figure out. Putting in this filter fixed the problem. So, change those Subaru filters (hers was a solid mass of black gook) after 90,000 miles folks and save some money on repairs and get your motor running right.

This kit fits great on 2012 Outback. Time will tell if it holds up like oem I did my sevice at 95000 miles. Mine started to fail at the tensioner I found traces of fluid seeping out of the seal around the piston and a grove on the face of the piston. Hope this kit gives my Subaru another 95000 miles. Oh also get yourself 2 gallons of Subaru blue coolant, oem Subaru thermostat, and a bottle of Subaru coolant conditioner.

Do Not buy these for a 2003 Legacy Outback. They do work on different subarus but for some reason the legacy you need a better axle. They only lasted about 5 days...

Easy install, works perfectly on my 2014 Subaru Outback

My situation was similar to that of previous reviewer StevenL. A 2002 Subaru Outback with a 2.5 L engine gave a P0420 code, which can mean a bad fuel/air sensor or a failing catalytic converter. Because the converter was about 2 years old and the sensors were original, (235,000 miles old) I opted to change the sensors. I bought this one, which fits in the port at the rear of the converter, and a Bosch 17018, which goes at the front of the converter because they received positive reviews and were priced right from Amazon. After detaching the electrical connectors and removing the header pipe and converter pipe as a unit (I needed to replace the gasket between the converter and resonator pipes so it made sense to me to avoid the contortions and bloody knuckles likely to result from in situ sensor removal) the sensors yielded to PB penetrant and leverage from a 22 mm wrench. I also chased the threads with a Lisle 12330 tool lubricated with anti-seize. The wires and electrical connectors on the sensors were the same as the originals, but the head ends were a bit different; perhaps the car came with Denso sensors. Amazon sells Denso and Bosch units; the Bosch sensors had good reviews and were less expensive. I reassembled the exhaust system, attached the electrical connectors, cleared the error code and ran the car through a drive cycle. The engine runs smoothly, the catalyst and sensors check out fine on my code reader, and the error code has not returned. The Bosch sensors have worked well so far, and, as an added bonus, were made in the U.S.

This anti-knock sensor fit my 1999 Subaru Outback perfectly and cleared the check engine light code right away. It was also a very good price.  Now our car runs much better.
