Designed for Small Turbo Applications

The G-Line series is intended for:

• Small-frame turbochargers
• Daily-driven performance cars
• Street builds
• Sleeper projects
• Moderate horsepower applications

Unlike oversized race intercoolers, the G-Line prioritizes efficient packaging and practical cooling performance.

Compact Core Dimensions

Overall Dimensions

• Length: 24.5 inches
• Height: 11.75 inches
• Thickness: 3 inches

Core Dimensions

• Length: 17.5 inches
• Height: 11.75 inches
• Thickness: 3 inches

The compact size helps improve fitment behind factory bumpers while still providing substantial cooling capability.

Large 3-Inch Inlet and Outlet

Connection Sizes

• Inlet: 3 inches
• Outlet: 3 inches

Benefits include:

• Improved airflow
• Reduced restriction
• Compatibility with many aftermarket piping kits
• Support for moderate boost levels

The larger connections help future-proof the intercooler for additional modifications.

6061 Aluminum Construction

Material

• 6061 Aluminum

Advantages include:

• Excellent heat transfer
• Lightweight construction
• Corrosion resistance
• Long-term durability

6061 aluminum is widely used in performance cooling systems because it offers an ideal combination of strength and thermal efficiency.

TIG-Welded Construction

Every Mishimoto intercooler is TIG welded.

Benefits include:

• Superior weld strength
• Increased durability
• Improved pressure resistance
• Long service life

TIG welding remains the preferred manufacturing process for high-performance intercoolers.

One-Piece Cast End Tanks

One of the standout features of the G-Line intercooler is its cast aluminum end tanks.

Advantages

• Improved airflow characteristics
• Greater structural strength
• Reduced risk of cracking
• Better resistance to boost pressure

Cast end tanks are often considered an upgrade over fabricated sheet-metal designs for many street applications.

Rated for 32 PSI

Maximum Boost Rating

• 32 PSI

This makes the G-Line suitable for:

• Street turbo builds
• Moderate-performance applications
• Tuned daily drivers
• Most small and medium-frame turbo systems

Few street vehicles operate beyond this pressure level, making the rating more than sufficient for most enthusiasts.

Stealth Black Finish

One feature that makes the G-Line unique is its appearance.

Black Powder-Coated Finish

Benefits include:

• Sleeper appearance
• Reduced visual attention
• Cleaner appearance behind grilles
• Professional look

Not every enthusiast wants a bright silver intercooler announcing modifications from half a mile away.

Universal Mounting Points
