My wife and I have three Subarus between us: a 2011 Forester non-turbo, a 2019 Crosstrek, and a 2021 WRX. (My wife's car, if you can believe it; I never drive it.) I keep oil and filters stocked for these cars, and sometimes RockAuto has closeouts, so I have a small variety of filters on hand...

I do. I got a bunch of these for a couple bucks on eBay: Really helps me stay aware of when the next change is due.

I have a 2019 Crosstrek with about 25k miles. I put in a K&N air filter when it was new and basically never looked at it again until yesterday. The car gets ordinary street and highway driving, no excessively dusty or dirty areas, and the filter didn't look super dirty when I checked it...

I've been following this forum for a while now, and I thought I might sum up what I've learned, for the amusement and edification of all. Filtration efficiency is the most important thing about a filter. Flow is the most important thing about a filter. Build quality is the most important thing...

When installing a filter on my Subaru engines, I like to use a cap wrench to install them. I can already feel a lot of you gearing up to tell me you don't need a wrench to install, and I know you're right, but hear me out first. I have two reasons. First: I have tendon problems in my wrists...

We put a car in storage over the winter with one of those little 1A trickle chargers on the battery to keep it topped up. It didn't work. The battery went dead, and I'm trying to figure out if it was operator error or something wrong with the charger. It's possible I chose a bad ground point...

Most of you will probably already be aware that the Tokyo Roki 15208AA160 "black" filter that comes on Japan-built Subarus is not available in the USA. US Subaru dealers replace it with 15208AA15A "blue", made by Fram, at the first oil change. It's widely understood that the Roki filter is...

Okay, guys, tell me if I've got this right. There is Champion, best known for spark plugs and batteries; there's Champ filters, made by Champion Labs; and there's Service Champ filters. As far as I have been able to determine, there's no connection between the two Champions. The spark plug and...

The thread asking about your first filter purchase, and the looking-back responses, got me to thinking about filter sizes. When I got started working on cars in the late 1970s, I was mainly working on Mopars from the '60s and '70s. They took these enormous filters which were about 6" tall by 4"...

My wife's daughter is bringing her van over this weekend for some fixing, and I said I'd do an oil change while I had it up on the ramps. Looked up the filter to order one, and found it's a cartridge filter. Not being a Toyota owner, this was a surprise to me. Watched a couple of YT videos and...

In a phone conversation today, Purolator confirmed to me that the red can "Classic" filters and the white can "Tech" filters are the same internally. They differ only by intended market, consumer vs. professional. I know this has been mentioned here before, but I figured it wouldn't hurt to...

I have two Subarus that use nominally the same filter, but I'm not sure what to think about what the Wix site has to say. If I go by what the cars were built with, I should be using a different Wix part number than if I go by the current catalog recommendation. We have an '11 Forester...

Wife's 2021 WRX came with a Subaru 15208AA170 filter. Lookup at Champ Labs says PH2808, both by vehicle application and by cross reference to the Subaru part number. My understanding is that Motorcraft FL-810 is made by Champ, and Champ's cross reference also says FL-810 matches PH2808. Is the...
