Brian Crower VALVES - 34mm INTAKE

Fitment: Mitsubishi 4G63 Engines in Eclipse and Evolution Models

Part #: BC3100

Overview

The Brian Crower 34mm Intake Valves are precision-engineered components designed to improve airflow and enhance the performance of Mitsubishi 4G63 engines, commonly found in Eclipse and Evolution models. These high-quality valves are ideal for enthusiasts and builders aiming to maximize engine response, reliability, and durability in high-performance applications. Whether you're upgrading for turbocharged setups, high-revving builds, or engine rebuilds, these valves help support your performance goals by providing consistent, reliable operation under demanding conditions.

Constructed from premium materials, the valves feature a robust design that ensures longevity and resistance to heat and wear. They are engineered to optimize airflow through the intake port, contributing to improved volumetric efficiency and power potential. Designed with precision machining, these valves help achieve proper seating and sealing, which is critical for maintaining compression and engine integrity during high-performance use.

Key Features

Brian Crower Intake Valves are crafted with performance and durability in mind, offering several key benefits:

• 34mm diameter for increased airflow capacity
• Made from high-quality, heat-resistant materials
• Precision-machined for optimal seating and sealing
• Designed to withstand high RPM and boost pressures
• Suitable for turbocharged and naturally aspirated engines
• Ideal for engine rebuilds, performance upgrades, and custom builds
• Engineered to support high-revving and high-performance applications

Construction & Design

The valves feature a durable construction with a focus on heat resistance and structural integrity. The high-quality materials and precise machining ensure consistent performance and longevity, even under the demanding conditions of high-performance engines.

Driving Feel & Feedback

Upgrading to these intake valves can contribute to improved airflow and engine responsiveness, supporting a more aggressive throttle feel and smoother high-RPM operation. They help your engine breathe better, translating into more immediate power delivery and enhanced driving engagement.

Installation & Fitment

These valves are designed as direct replacements for the factory intake valves on Mitsubishi 4G63 engines. Proper installation requires standard engine rebuild procedures, including valve seat machining and proper valve clearance setup. Compatibility should be verified against your specific vehicle and engine build.

What’s Included

The package includes a set of high-performance intake valves designed for Mitsubishi 4G63 engines. Hardware, such as retainers and seals, are not included and should be sourced separately if needed.
