Hello, iv just bough a 2015 srt gc with capristo exhaust and was wondering, what are the three plastic balls in the engine bay for? Tried to google it with no luck. Thanks in advance!

They look like vacuum balls. Are those vacuum hoses going to it? Trace it to see if they tie into the exhaust system somewhere.

My thoughts are that its a vacuum reservoir, purpose is to provide vacuum to something under heavy acceleration when vacuum goes away. Should have 2 lines, one going to a vacuum supply and the other providing vacuum to something like brakes, HVAC, cruise control.

Thanks for you input! The pierburg you can see on one picture is a boost pressure valve 🤨 and the line feed to the engine as you can see on other pictures. Really cant explain whats that for lol… maybe someone who knows these engine could tell :/ are the any sites online with schemes etc? Iv been driving bmws for last couple of years and theyre gold when you need to find something online.
