Compact Cooling, Maximum Performance

Cooling is one of the most critical factors in high-performance builds, yet it’s often overlooked until temps creep past safe limits. Whether you’re building a turbo Honda Civic, an Evo track car, or a custom swap project where space is at a premium, you need a radiator that not only fits but also performs. That’s exactly what the CSF Universal Half Radiator delivers.

Finished in a sleek black coating and paired with a 12” SPAL high-performance fan and shroud, this radiator is engineered to provide compact, race-ready cooling for some of the most demanding setups. Featuring CSF’s patented B-Tube Technology, -16AN and slip-on fittings, and universal fitment for 1992–2000 Honda Civics as well as Mitsubishi Evolution 7/8/9, it’s one of the most versatile and effective half-size radiators on the market.

Why Choose a Half Radiator?

Half-size radiators are a staple in motorsport and swap culture. They offer flexibility and performance where traditional full-size radiators can’t.

• Space Savings: Essential for engine bays with large turbos, intercooler piping, or custom fab work.

• Lightweight Design: Reduces front-end weight for better balance.

• Universal Fitment: Works across multiple platforms and swap projects.

• Efficient Cooling: When engineered properly (like this CSF unit), they can outperform outdated full-size designs.

For serious builds, especially those where packaging space is limited, a high-performance half radiator is the smart solution.

CSF’s Exclusive B-Tube Technology

At the heart of this radiator’s performance is CSF’s B-Tube Technology, a patented design that increases efficiency by up to 15% compared to conventional tubes.

How It Works:

• B-Tube Shape: Instead of a traditional oval tube, CSF’s B-shaped design increases the contact area with coolant.

• Strength + Efficiency: Thinner walls allow more tubes per core without sacrificing durability.

• Better Heat Transfer: More surface area means faster, more efficient cooling.

Combined with multi-louvered fins, the B-Tube core ensures airflow is maximized, pulling heat away as efficiently as possible.

Compact Design, Big Performance

Don’t let the “half-size” name fool you—this radiator is built to perform like a heavyweight.

• 2-Row Core: Packs serious cooling into a small footprint.

• Durable Black Finish: Protects against corrosion while looking sleek under the hood.

• High-Performance Fan + Shroud: The included 12” SPAL fan is one of the most respected names in motorsport cooling.

• -16AN & Slip-On Fittings: Gives builders flexibility for traditional or AN-style plumbing setups.

This combination makes it a drop-in solution for Civics and Evos, but also a favorite among custom swap builders.

Direct Fit + Universal Versatility

The CSF Universal Half Radiator isn’t just for Civics and Evos—it’s for builders who want flexibility.

• Direct Fit:

  • 1992–2000 Honda Civic

  • Mitsubishi Evolution 7/8/9

• Universal Applications:

  • Custom turbo builds

  • Engine swaps (K-swaps, J-swaps, LS swaps, etc.)

  • Tight engine bays where full-size radiators don’t work

This versatility is what makes it such a go-to option—it’s equally at home in a daily-driven turbo Honda as it is in a stripped-down time attack Evo.

Benefits for Track and Street

For Track Cars:

• Handles prolonged abuse without heat soak.

• Lightweight design reduces front-end load for sharper handling.

• Compact size frees space for additional cooling or turbo hardware.

For Street Builds:

• Reliable performance for spirited driving.

• Sleek look under the hood with black finish and clean AN fittings.

• Plug-and-play with common platforms.

This radiator proves that you don’t need to compromise between performance and packaging.

Installation Notes

• Plug-and-Play Fitment: Bolts directly into EG/EK Civics and Evo 7/8/9.

• Custom Friendly: Universal sizing and fittings make it adaptable for swaps.

• Fittings Included: Both -16AN and slip-on options for plumbing flexibility.

• Shroud + Fan Ready: Pre-installed SPAL fan and shroud simplify installation.

For custom applications, professional installation and proper coolant bleeding are recommended.

Why SPAL Fans Matter

SPAL is the gold standard in high-performance cooling fans. The included 12” SPAL fan ensures airflow even in low-speed or high-heat scenarios like grid staging or traffic. Combined with a precision-fit shroud, airflow efficiency through the radiator core is maximized.

This isn’t a “one-size-fits-all” aftermarket fan—it’s the same kind of equipment trusted in motorsport builds worldwide.
