## ⚙️ Key Features

-   Large-diameter clamp for the clean-air intake path
-   Confirmed with Stage 1 / Tier 1 induction components
-   Maintains an airtight joint under vibration
-   Must match the hose or elbow outside diameter

-   80mm (Volvo assembly listing)
-   Quantity varies by assembly, most commonly one

## 🔌 Function

Secures the air-cleaner, elbow or manifold connection so filtered air cannot leak or draw in dust.

## ⚠️ Common Signs of Failure

-   Dust tracks downstream of the filter
-   Intake whistle
-   Loose hose or elbow
-   Clamp corrosion or distortion
-   Hose split beneath the clamp

## 🛠️ Service Notes

-   Match the clamp to the hose outside diameter so the band closes well within its working range rather than at the very end of its travel
-   Position it over the spigot behind the bead or barb, with the screw where a driver or spanner can still reach it once everything is refitted
-   Tighten to seal, not to crush — an over-tightened worm-drive clamp cuts into soft hose and starts the leak you were trying to stop
-   Renew clamps when a hose is changed rather than reusing them, and keep band, housing and screw all marine-grade stainless so the clamp does not corrode against itself
-   Where two clamps are fitted to one connection, stagger the screw heads and recheck both after the first running period
