Supercharger Idler Pulley Problem

SlowWhite · 10-20-2023, 05:34 AM

I’m about to change the belt on my 2017 (only 8k miles but it’s cheap insurance). I was reading here that one of the idler pulleys is known to fail and cause the supercharger belt to shred so I want to replace that too but I can’t find a part number. Does anyone happen to know the part number of that pulley? Is there an aftermarket part that’s better (I rather keep it OEM though).

Thanks
