Description

327FA-BLU Velocity Stack – Fits GX120-GX200, Clone & Predator Stock Carburetors (2.5" OD)


Maximize airflow and engine performance with the 327FA-BLU Velocity Stack, engineered to fit most Honda GX120–GX200, Clone 196cc, and Predator 212/224 stock carburetors. Designed with a precision-machined air radius, this stack improves air velocity and intake flow compared to standard flat or straight filter adapters—delivering noticeable gains in throttle response and power in classes where velocity stacks are allowed.


Crafted from CNC-machined 6061-T6 aluminum, the 327FA-BLU features a durable anodized blue finish that resists corrosion and adds a high-performance aesthetic to your engine setup.


Fits 2.5" ID air filters. Please verify your filter size before ordering.


Key Features & Benefits:

  • Improved Airflow Efficiency:
    The radiused bell-mouth design increases intake velocity and smooths airflow into the carburetor, helping your engine breathe more efficiently.
  • Race-Ready Construction:
    Made from lightweight and durable 6061-T6 aluminum, precision CNC-machined for consistent quality and a professional finish.
  • Anodized Blue Finish:
    Deep blue anodizing offers corrosion resistance and a sharp visual upgrade to your engine bay.
  • Rulebook Friendly:
    Velocity stacks are recommended in all classes where permitted. Always check your racing rulebook before using.
  • Easy Fitment:
    Installs in place of standard filter adapters—compatible with most small engine racing carburetors using a 2.5" OD filter.


Fitment Compatibility:

Fits most stock small-block carburetors, including:

  • Honda GX120–GX200 (Keihin Carburetors)
  • Clone 196cc Engines (Huayi, Ruixing carbs)
  • Predator 212 & 224cc (Harbor Freight "Hemi" and "Non-Hemi" SP versions)
  • Tillotson 196R / 212R (Tillotson PK carburetors)

Air Filter Compatibility: Designed for use with 2.5” ID air filters. Check your filter's inner diameter to ensure a proper seal.


Whether you're optimizing for max flow on the dyno or race day performance, the 327FA-BLU Velocity Stack is a simple upgrade that can yield real results. Swap out your basic filter adapter and let your engine breathe the way it was meant to.

FAQ

What does a velocity stack do on a small engine carburetor?

A velocity stack improves airflow into the carburetor by using a radiused bell-mouth shape. This design increases air speed and intake efficiency, helping the engine breathe better, especially at higher RPMs.


What size air filter fits this velocity stack?

The 327FA-BLU is designed for air filters with a 2.5" inner diameter (ID). Be sure to measure your filter to ensure proper fitment and sealing.


Will this fit my Predator 212 or 224 engine?

Yes! This stack fits stock carburetors found on Predator 212 and 224 engines, as well as most Clone 196cc and Honda GX120–GX200 engines. It also fits Tillotson PK carbs used on the 196R and 212R.


Is this velocity stack legal for racing?

Velocity stacks are legal in many stock and modified racing classes, but not all. Always check your class or sanctioning body’s rulebook before using one in competition.


Is this made from billet aluminum?

Yes. The 327FA-BLU is CNC-machined from 6061-T6 billet aluminum, then anodized blue for corrosion resistance and a performance look.
