Made for turbocharged Class 8 and heavy-duty diesel engines, the Gates 26203 air intake components for the 2017-2021 International LT625 12.4L / 14.9L and other vehicles is a Green Stripe ring-retained turbocharger hose.
Lower boost, a cracked or split hose, or a section that has gone soft can mean the hose is wearing out. These signs alone don't prove this hose is the problem, since a loose clamp in the air path could be behind them.
This hose also fits the 2018-2026 International RH613 12.4L / 12.7L and the 2012-2025 Freightliner Cascadia, plus many other heavy-duty trucks. Open the "Vehicles it fits" section to look up your exact model and engine.
