True dual 102mm legs for charge-pipe and intercooler routing that needs reach.

Engineered hose hardware — not cosmetic parts — for tuners running past OEM specs. Every coupler, elbow and vacuum line is built to survive the boost, heat and chassis flex that breaks OEM rubber.
From a 3mm vacuum reference line to a 102mm charge-pipe elbow — every Sierra part is engineered to the same construction spec, then verified against it.

True dual 102mm legs for charge-pipe and intercooler routing that needs reach.

Short-leg geometry for tight engine bays where the OEM rubber sat folded.

The flex hump absorbs vibration and shaft misalignment so the joint never fatigues.

Step cleanly between two diameters without a kink or a flow-killing collapse.

The workhorse join for intake-to-intercooler and throttle-body connections.

Single-layer extruded silicone, 3–6mm ID — wastegate, BOV, brake booster and MAP signal.

OEM rubber dries out and cracks at 70k miles. Sierra reinforced hose is built to outlive the engine it's bolted to.
Factory rubber dries out, hardens and splits under years of heat cycling. Silicone doesn't. Sierra hose ends the failure mode instead of replacing it on the same schedule.

A modified engine doesn't live in a lab. It sees heat soak in traffic, ice on a winter start, and chassis flex on a track curb — often in the same week. Sierra hose is specified for the worst of all three, not the average of them.
