Rein Idle Control Valve Hose - E30 325i E34 525i E36 325i 325ic 325is M3

Product Details

The factory Idle Air Control Valve hoses are subjected to decades of intense engine bay heat, oil vapor, and constant engine movement. Over time, the factory rubber hardens, becomes brittle, and develops hairline splits on the underside where you can't see them without removing the throttle body. These unmetered vacuum leaks allow unmeasured air into the engine, throwing off your fuel trims and ruining your idle quality.

This replacement hose from Rein Automotive is the perfect, cost-effective fix to restore crisp throttle response and a rock-solid idle. Molded to exact OEM dimensions from high-grade, heat-resistant rubber, it resists the breakdown caused by aggressive thermal cycling and fuel vapors. It installs exactly like the factory piece, providing an airtight seal that ensures your engine only gets the air the MAF sensor actually accounts for.

Features
