EC 442INT EC Intake Manifold 1.125 HL to Clone/Honda/Predator

EC 442INT Billet Intake Manifold

Fits 1.125” HL & EC X380 Tillotson Carburetors to Honda/Clone/Predator Engines

Purpose-Built for Open Class Dominance

The EC 442INT Billet Intake Manifold is engineered to adapt 1.125" Tillotson HL-series carburetors, including the industry-leading EC X380 Intimidator, to popular small block racing engines such as the Honda GX200, Clone 196cc, Predator 212/224, and Tillotson 196–268cc platforms.

Designed for high-performance open-class builds, this manifold delivers the airflow, vacuum signal, and precision fitment required to win races. Whether you're running billet or ported cast heads, the 442INT gives your engine the breathing room and tuning control needed for podium-level performance.

Why Choose the EC X380-6 Intimidator Carburetor?

For maximum results, pair this intake with our X380-6 Intimidator—the winningest 1.125” carburetor in open OHV racing.

Compared to the HL-380A/B (originally designed for flatheads), the X380-6 is specifically tuned for OHV engines and features:

• A custom fuel circuit optimized for methanol
• Superior throttle response and mid-to-top end power
• More consistent tuning with fewer compromises

Precision CNC Machining for Maximum Airflow

Crafted from high-quality billet aluminum, the 442INT is CNC-machined to precisely match popular big valve intake port shapes, ensuring:

• Smooth, unrestricted laminar airflow
• No turbulence or misalignment at the manifold-port interface
• Accurate fuel atomization and vacuum pulse delivery

A strategically located pulse hole ensures reliable diaphragm operation at high RPM—critical for maintaining fuel delivery and throttle response.

Intake Runner Length Matters

Thinking of tuning intake length for powerband optimization? Here’s what you need to know:

• Diaphragm-style carbs (like the HL-series) require a strong intake pulse to operate effectively.
• Longer intake runners reduce signal strength and responsiveness.
• Intake tuning involves a complex balance of carb size, cam timing, port shape, and valve size.

The 442INT is engineered to strike the perfect balance—maximizing airflow without sacrificing vacuum signal strength—making it race-ready out of the box.
