What This Hose Is and Where It Goes
This is a 4-inch by 6-inch silicone hump hose, three ply construction with three wire reinforcement rings molded in. It's built for the cold side of the CAC (charge air cooler) system - the piping that runs boosted air from the intercooler back to the intake manifold, after the turbo but before it hits the engine.
The hump shape and those reinforcement rings aren't decorative. They let the hose flex and absorb vibration and slight misalignment between the two pipe ends without collapsing under boost pressure. A straight hose without rings can suck in or balloon out over time and start leaking boost - that's usually when a truck starts losing power and nobody can figure out why.
This one is a direct replacement for both Volvo and International (Navistar) applications, which is why you'll see it cross to numbers from both manufacturers plus a couple aftermarket lines. Confirm your engine and chassis combo before you order, since CAC routing changes across model years.
Why These Numbers Cross and What to Check
8072886 is the headline number, but it interchanges with International/Navistar part numbers like 3558834C1, 3625343C1, 3539944C1 and 3539944C2, plus aftermarket references like F01612BS352 and 26203. These all point back to the same 4x6 hump hose spec - same ID, same length, same three-ring reinforcement.
Where guys get tripped up is assuming every 4x6 hump hose is interchangeable just because the dimensions sound close. Wall thickness, ply count, and ring spacing can differ enough that a hose seats but doesn't seal right under boost. Multiple part numbers landing on the same physical hose usually means different OE catalog listings or supersessions over the years, not that any 4x6 hose will do.
Rule of thumb - pull the number off your old hose or look up your VIN before ordering. If the old hose is too degraded to read, measure ID at both ends and count the reinforcement rings so you're not guessing.
Ordering From PartStop
We're in Tacoma and keep this stuff on the shelf because CAC hoses fail more than people expect, especially on trucks running higher boost or logging a lot of highway miles in heat. Local guys can get same-day pickup instead of parking a truck for two days waiting on a hose.
We ship nationwide too, so if you're not near Tacoma it still shows up fast. Every hose we sell carries a 6+ month warranty, and if something's off - length, ID, whatever - we'd rather sort it before it goes on a truck than after.
At $17.99 it's cheap enough that stocking a spare on the shelf makes sense for a shop running several Volvo or International units.
8072886 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 8072886. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 8072886 fit my International truck?
Likely, but confirm with your engine model and CAC routing first - International used this hose across several chassis and engine combos, and the safest check is matching it against the number stamped on your old hose or your VIN.
Is this the same as F01612BS352?
It cross-references to the same 4x6 hump hose spec, but always compare ID measurements and ring count against your old part before installing - part numbers can point to the same design without being identical in every production run.
How do I know if my hose has actually failed versus just a loose clamp?
Check for cracking, bulging, or soft spots in the silicone, especially near the ribs. If the clamps are tight and torqued right but you're still losing boost pressure, the hose itself is probably the problem.
