Intake Couplers & Elbows

Intake couplers and elbows are the flexible joints and bends that connect the pieces of an air intake or charge air system. On a diesel, a split or loose coupler means unfiltered air getting into the engine or boost escaping before it reaches the cylinders, and both cost you power and can cause damage over time.

This collection includes silicone hose couplers in straight, reducer and hump styles, universal intake tubes in straight lengths and 45 and 90 degree bends, and fittings and bungs for adding sensors to a custom intake. Most parts are sized by inside diameter, so measure the pipes you are joining before you order. Brands include AEM, Vibrant, PPE, Fleece and K&N.

These parts are useful for building a custom intake, repairing a cracked factory boot, or adapting an aftermarket intake to a different turbo inlet. If you are working on the pressurized side between the turbo and intercooler, also see our intercooler pipes and hoses for boots and clamps rated for boost, and our air intake systems for complete kits.
