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.

Yamaha introduced the YFM660R as a 2001 model and continued offering it through the 2005 model year. The official 2004 intake diagram shows separate Carburetor Joint 1 and Carburetor Joint 2 components.
Trim names, color editions, and model suffixes may vary by market. Confirm the OEM numbers and physical configuration of both original intake boots.

Domande frequenti sulla compatibilità
Questa parte è compatibile con il mio modello e anno specifici?
This two-piece intake manifold set is designed for compatible 2001–2005 Yamaha Raptor 660R YFM660R ATVs.
It may also fit selected Limited Edition and Special Edition models from the same YFM660R generation. Your ATV should use intake-joint numbers from both the 5LP-13586 and 5LP-13596 families.
The original boots must also match the mounting positions, openings, angles, vacuum-port locations, and shapes shown in the product images.
Devo corrispondere al numero di parte OEM?
Yes. Matching both OEM numbers is strongly recommended.
For Carburetor Joint 1, check for:
5LP-13586-00
5LP-13586-01
For Carburetor Joint 2, check for:
5LP-13596-00
5LP-13596-01
Your ATV normally uses one joint from each number family. Do not purchase two identical joints unless the product configuration has been independently verified.
Different suffixes may appear in parts catalogs or on replacement components, but the complete shapes and mounting arrangements must also match.
A quali modelli o situazioni non si adatta questa parte?
This intake manifold set is not confirmed for:
Yamaha Raptor 700 or Raptor 700R models
Yamaha Raptor 350 models
Yamaha Grizzly 660 models
Yamaha Rhino 660 models

ATVs fitted with aftermarket carburetors requiring different openings
Engine-swapped or heavily modified vehicles

Do not assume that all Yamaha 660cc ATV engines use the same intake manifold boots.
