Mitsubishi 3.8L 6G75 MN135871 Intake Manifold Repair Kit

Intake Manifold Repair Kit (Bushings) for Mitsubishi 3.5L & 3.8L

Eliminate intake manifold noise and restore engine stability without the high cost of a complete manifold replacement. Over time, the factory vortex flap bushings wear out due to high temperatures and mechanical loads, causing the flaps to rattle and leak air.

While the manufacturer recommends replacing the entire assembly, our repair kit allows you to replace only the worn-out bushings, saving you thousands in repair costs.

Common Symptoms of Worn Intake Bushings

• Rattling or Tapping Noise: A distinct "clatter" coming from the intake manifold.

• Reduced Engine Power: Inefficient airflow management affects torque.

• Increased Fuel & Oil Consumption: Poor combustion caused by unstable flap geometry.

• Error Code P0521: Often appears during computer diagnostics.

• Rough Idling: Unstable engine performance at low speeds.

Why Choose the Klifex Repair Kit?

• Precision Match: Designed to mirror the original specifications for a perfect mechanical fit.

• Cost-Effective: Fix the root cause for a fraction of the cost of a new OEM manifold (MN135871).

Important Installation Note

Because wear on the intake manifold seats varies from vehicle to vehicle, these bushings may require minor individual adjustment (custom fitting) to match your specific collector’s wear level. There is no "one-size-fits-all" for a worn manifold seat, so precision fitting ensures the best possible seal and noise reduction.
