The BOOST Products Cobra Head silicone elbow makes a compact 90-degree turn where a standard long-radius coupler takes up too much room.
Fitment Information
- For custom turbocharger, intercooler, intake, coolant, and other engine-bay plumbing projects requiring a compact 90-degree silicone elbow
- Available inside diameters: 2.5 inch / 63.5mm, 3.0 inch / 76mm, 3.5 inch / 89mm, and 4.0 inch / 102mm
Fitment Note
This is a build-specific hose, not a vehicle-specific replacement. Measure the outside diameter of the tubing or connection point before ordering. The listed size is the hose inside diameter. Silicone is elastic by approximately 1 to 3mm, so choose the correct size for the connection and account for the hose wall thickness when selecting clamps.

Product Description
The Cobra Head is for custom piping where the route has to turn 90 degrees without filling the engine bay with a bulky, wide-radius elbow. It works well around passenger-side throttle bodies, intercooler piping, turbo inlet plumbing, and other low-clearance areas where packaging matters.
Each silicone elbow has textile reinforcement to handle boosted pressure and vacuum conditions, with a temperature range up to 220°C. Choose black for a more understated engine bay or blue for a traditional performance look.
Before You Buy
Do not use this hose for fuel or oil lines. Confirm both the pipe outside diameter and available clearance before ordering. The compact Cobra Head profile is useful when space is limited, but it should still be positioned so the hose is not rubbing against hot exhaust parts, sharp edges, or moving accessories.
