25mm Performance Intake Manifold Pipe (56-2) for 110cc 125cc 140cc 150cc Pit Dirt Bike ATV

Product Overview

Upgrade your small-bore engine’s breathing with this 25mm Performance Intake Manifold (Model 56-2). Designed for 110cc to 150cc horizontal engines, this oversized manifold allows for a higher volume of oxygen to reach the combustion chamber. By increasing the intake bore to 25mm, your engine can burn fuel more efficiently at higher RPMs, resulting in increased speed and snappier throttle response. Whether you are racing Pit Bikes or upgrading your TaoTao ATV, this high-strength pipe is the key to unlocking hidden power.

Key Features

• Increased Intake Volume: The generous 25mm bore allows for a significant increase in airflow, supporting larger carburetors and high-performance engine builds for better top-end speed.
• Optimized Combustion: By delivering more oxygen to the cylinder, this manifold helps optimize the air-fuel ratio, enhancing the power stroke and overall engine responsiveness.
• High-Strength "Skeleton" Design: Features a reinforced construction with fine workmanship, ensuring the pipe resists cracking and aging even under extreme off-road vibrations.
• Heat-Resistant Alloy: Made from premium materials that won't warp or degrade when exposed to the high temperatures of an air-cooled engine.
• Direct Performance Upgrade: A straightforward bolt-on replacement for the stock, restrictive intake pipes found on standard 110cc-150cc engines.
