The MITSUBISHI 4G61-T Engine Valve Guide (OEM: MD126605) is an essential high-performance component designed specifically for turbocharged 4G61-T engines. These precision valve guides play a critical role in maintaining proper valve alignment, reducing oil consumption, and withstanding the extreme conditions of forced induction - ensuring your turbo engine maintains optimal compression and longevity.

Key Features & Benefits

✔ Turbo-Engine Specific Design
Engineered to Mitsubishi's exact MD126605 specifications, these guides are optimized for the higher temperatures and pressures of turbocharged applications. The precision dimensions ensure proper valve stem alignment even under boost, preventing issues like oil leakage and premature turbo wear.

✔ High-Temp Alloy Construction
Made from specialized heat-resistant bronze alloy, these guides outperform standard replacements in turbo environments. The material composition provides superior heat dissipation and maintains dimensional stability when exposed to the extreme thermal cycling common in forced induction engines.

✔ Enhanced Lubrication Design
Features a micro-grooved inner surface that maintains optimal oil film retention on valve stems. This critical design element reduces friction at high RPMs while preventing the oil starvation that can lead to catastrophic failure in turbo applications.

✔ Boost-Ready Durability
The reinforced construction handles increased cylinder pressures from turbocharging, helping maintain proper valve seating and preventing compression loss - essential for preserving power output and preventing turbo lag.

Why These Valve Guides?

• Turbo-specific engineering - Designed for forced induction demands

• Precision fitment - Exact OEM MD126605 specifications

• Long-term reliability - Outlasts standard guides in high-performance use

Professional Installation Advice

• Mandatory Machining: Requires professional installation with proper reaming to achieve perfect tolerances for turbo applications

• Complete Valve Service Recommended: For best results, install with new valve stem seals and inspect valves/seats

• Turbo Maintenance Tip: Always check valve guide wear when servicing turbo systems - excessive play can lead to oil consumption issues

Engineered to meet the rigorous demands of turbocharged performance, these OEM-spec valve guides deliver the precision and durability needed to keep your 4G61-T engine running strong under boost. Ideal for rebuilds, performance upgrades, or maintaining factory reliability in your turbo Mitsubishi engine.
