AOS/catch can?
 

Does anyone make (and has anyone installed) an AOS or an oil catch can on a 2nd gen BRZ?

I put a Crawford AOS on my 2019, was wondering if there’s an equivalent for the 2nd gen car.

Thanks!

Don't risk engine warranty for something that won't be an issue, car has port + direct injection.

lol wat

Say that to Subaru dealership if you need warranty work on engine and they denied. Get a lawyer, tell them all about Magnuson-Moss Warranty Act and how you making modifications to engines intake system didn't affect engine.

Are you having a case of the Monday's?

Subaru could also just "void your warranty" (:thumbdown:) because you have black hair, or wore a gray shirt when you took your car in that day, or just because they feel like it.

lol, yes me having black hairs is same as making changes to engine's intake system, let me know what you are smoking, seems like good stuff. Just call your dealership or SOA now and ask them if they would take warranty claim on engine if you have catch can installed.

Anyways what's the point of having catch can on these? The engine has port injection along side direct injection.

yes, because that worked so well for this guy...

unless your lawyers are salary, your experience isn't going to be any different.

Exactly, that post was my sarcastic reply to the guy above.

Interesting read, thanks for sharing. Oddly enough I never came across that.

Whoosh...

Do you think you need an AOS and/or catch can? My ‘17 has been only car of several I have streeted and tracked that used practically no oil over 5k miles + 4 to 6 track days between oil changes, hoping the ‘23 is similar!

It wasn't out of concern of oil usage that I was thinking of an AOS. It was because of the potential for carbon build-up on the intake valves in a direct injection engine. I didn't realize the 2nd gen 2.4 engine in the BRZ was both direct and port injected.

I believe the 1st gen 2.0 BRZ engine is only direct injected, which is why I put a Crawford AOS on it.

1st-gen was also both direct- and port-injected!

It was?! Well, then I fitted an AOS for nothing I guess!

Thanks!

As long as it looked cool! No harm, but doubtful there was any benefit at all! Someone else on these forums put his up for sale after it collected barely a couple of ounces over 1000s of miles and a few track days :D

Yes, that's the "D-4S" is. It was basically Toyota's only contribution to engine development. Thought this was common knowledge.

But I realize not everyone who likes these cars are serious gearheads who grew up around race cars and modifying their own cars since they were 16.

You can be neither and still know that. Not saying everyone should.

join date is going to have a significant effect on that.

anyone that joined before 2015 was almost directly involved in learning the history of the car. anything after that is going to be a toss-up. some will care about the lineage, more are taking the car at face value.

WTF does join date have anything to do with anything?

I think my join at z31.com was in 1998? And that had already been around for years. It's called doing research, something the kids seem averse to, because it takes a few minutes.

No, I'm not a boomer, I'm only 41, so depending on what you ascribe to, only a millenial.

It has to do as much as need to be a "serious gearheads who grew up around race cars and modifying their own cars since they were 16". It doesn't take any of those (join date, modding cars since 16, growing up around race cars etc).

I am 32, I had no interest in cars till 2018. To be frank, it doesn't take more than one nut loose to know about cars. I know what engines and transmissions are in sedans, minivans, SUVs from all Japanese and Korean brands, that's because I have more than one screw loose :lol:
