Whether you're exploring remote trails or building a performance-forward rig, the CSF x Titan Motorsports Oil Cooler is the ultimate upgrade to keep your Ineos Grenadier running cool, strong, and ready for more.
CSF Race, in collaboration with Titan Motorsports, are proud to offer a game changing transmission oil coolers engineered for the Ineos Grenadier. This high-performance cooler delivers the temperature control serious off-road enthusiasts demand.



Design & Engineering
When transmission fluid overheats, performance suffers and long-term damage becomes more likely. CSF & Titan Motorsports engineers identified this critical vulnerability during extensive real-world testing of Grenadier under demanding conditions. Having to stop and wait for your transmission to cool down is more than just an inconvenience, it is a limitation that shouldn't exist in an SUV like this.
The transmission oil cooler eliminates the concern of overheating. The advanced design features CSF's High Efficiency Bar/Plate Core with All-Aluminum tanks for rugged durability. This cooler is an ideal upgrade for the Grenadier and offers several key benefits:
- Keeps transmission fluid under control, even in the toughest off-road conditions
- Extends transmission life and reliability
- Improves cooling efficiency for towing, crawling, and overlanding
- Designed for easy installation
- Delivers peace of mind through proven CSF engineering
CSF vs OEM
The factory transmission oil cooler for the Grenadier is definitely ample for daily driving and even some off-roading and towing. However, the OE cooler can’t always keep up in adverse conditions. Especially in more extreme off-roading. The CSF design offers:
- 39% Larger Core Volume: Features two additional rows of oil cooling and a thicker 55mm core (vs. OEM 45mm core) for improved heat dissipation.
- Upgraded Core Design: replaces the fragile Tube & Fin core for a Heavy-Duty Bar & Plate core that offers unmatched durability for off-road abuse and harsh environments.
- TIG-Welded End Tanks: Stronger and more durable than the factory’s brazed construction, reducing the risk of leaks.
- Corrosion-Resistant Finish: Satin black coating provides long-lasting protection against debris, salt, and oxidation.
With enhanced cooling performance, increased durability, and precision engineering, this Transmission Oil Cooler is the perfect solution for Ineos owners pushing their rigs to the limit.
