Lexus 2008-2014 ISF V8 5.0L High-Performance Cooling Solution with Silicone Hose Kit

In development since 2016 and finally a reality, this cooling upgrade combines innovative technology with premium materials to deliver unmatched performance and reliability. Initially conceived as an integrated cooling solution to complement our Side-Ducted Oil Cooler, we waited for the market and technology to align. That time is now.

Partnering with CSF Race, we’ve introduced a groundbreaking upgrade to the OE cooling setup. Utilizing advanced B-tube technology and 5mm high-efficiency B-core fins, this design improves cooling efficiency by up to 15% compared to standard radiators. The integrated transmission cooler core ensures fluid preheating and coupling with the coolant system, keeping operating temperatures in check without the need for a large secondary trans cooler. This approach enhances cooling recovery and minimizes heat soak, providing exceptional responsiveness under demanding conditions.

Paired with this advanced radiator is the HPS High Temp 3-ply Reinforced Silicone Radiator Hose Kit in striking blue. Designed to replace stock OEM rubber hoses, which weaken over time, these premium silicone hoses withstand extreme high-temperature and high-pressure conditions while maintaining peak performance during competition or daily driving. Featuring precise bends and curves, the kit ensures a seamless fit for Lexus ISF models from 2008 to 2013. Each kit includes stainless steel clamps for hassle-free installation.

Key Features:

• Enhanced Efficiency: B-tube technology increases heat transfer surface area by 15%, leveraging dual liquid laminar flow for superior cooling.
• 5mm Fin Technology: Optimized for OE-level performance, delivering peak cooling in competition or daily driving.
• Integrated Transmission Cooler Core: Maintains fluid preheating and coolant coupling for balanced operating temperatures.
• Durable Construction: Satin finish aluminum end tanks, TIG welded, and pressure tested to 35Psig.
• Direct Fit Design: Includes all connections and mounts for the AC condenser and OE fan shroud.
• Precision Engineering: Supports multiple model years with step-nipple designs and accommodates variations like larger overflow fittings on 2010 models.
• HPS Silicone Hose Kit: 3-ply reinforced design rated for up to 350°F, offering superior durability and efficiency compared to universal hoses.

Technical Specifications:

• B-Tube Technology: Dual-layer design increases efficiency by offering the performance of two smaller tubes in the same space as one.
• Max Temperature Rating: 350°F (HPS Hose Kit).
• Premium Materials: Aluminum end tanks and stainless steel clamps for lasting reliability.
• FIGS Branding: Authenticity guaranteed.

This cutting-edge cooling solution is designed to meet the demands of Lexus ISF owners, providing enhanced performance, reliability, and peace of mind for both track and street use. Whether you're replacing aging components or upgrading for competition, this package delivers.
