What This Hose Is and Where It Lives
This is a 5-hump silicone coupler, 82mm ID, 150mm long, with 4 flanged rings molded in to keep your clamps from walking off under boost pressure. It's not a straight coupler - the humps let it absorb engine movement and vibration between the CAC piping without cracking, which is exactly how the stock rubber fails after 5-7 years of heat cycling.
On Volvo FH and FM trucks this section sits in the charge air cooler routing between the turbo and the intercooler, or intercooler to intake depending on which junction you're replacing. Silicone runs cooler and lasts longer than the factory rubber, which is why most shops just upgrade to silicone once the original cracks instead of chasing another rubber piece.
F01616S352 is the aftermarket part number for this exact hose - same dimensions, same 4-ring flange design.
Matching the Numbers to Your Truck
20561450 is the Volvo number stamped or printed on the OE hose. 20589122 and 20574213 show up as superseded or running-change numbers Volvo used across different FH/FM production years - Volvo revises these part numbers more than most manufacturers, so don't panic if your old hose has a different number than what you searched.
What actually matters for fitment is the physical spec: 82mm ID, 150mm length, and that 4-flange-ring pattern. If your old hose measures out different - even by a few mm - these numbers won't help you, because Volvo used several ID/length combos across the CAC piping on the same chassis depending on engine and cooling package.
Surest way to confirm: measure the old hose or pull the number off it directly, then run it against your VIN if you're not sure which position on the truck it goes. We're happy to check it against the number you've got before you order.

Frequently asked questions
Does 20561450 fit my Volvo FH?
Depends on the year and which CAC junction you're replacing - Volvo used this hose across multiple FH/FM configurations, but always confirm against your VIN or the number physically on your old hose before ordering, since spec is what matters here, not just the model name.
Is this the same as the F01616S352 crossed part?
Yes - F01616S352 is the aftermarket number for this exact silicone hose, same 82mm ID, 150mm length, 4-flange design. It's not a Volvo-branded piece, it's the aftermarket equivalent built to that spec.
Why does silicone cost more than a rubber replacement hose?
Silicone holds up to heat and boost cycling a lot longer than rubber before it cracks at the humps - most guys switch to silicone once because they're tired of replacing rubber every couple years.
