Intake Manifold Boots for Yamaha Raptor 660R 2001–2005

Product Overview

Restore a secure and properly sealed connection between the dual carburetors and engine with this two-piece intake manifold boot set, designed for compatible 2001–2005 Yamaha Raptor 660R ATVs.

These carburetor intake joints replace original boots that have become cracked, hardened, loose, distorted, or difficult to seal after prolonged exposure to engine heat, vibration, fuel vapor, dust, and off-road riding conditions.

Damaged intake boots may allow unmetered air to enter the engine, potentially causing difficult starting, unstable idle, hanging RPM, hesitation, surging, inconsistent throttle response, or a lean-running condition.

This set includes the two different intake joints required for compatible YFM660R dual-carburetor applications and replaces Yamaha numbers in the 5LP-13586 and 5LP-13596 families.
