HEL Oil Cooler Kit | 23+ Civic Type R FL5, 23+ Integra Type S DE5

Fits:

• 2023+ Honda Civic Type R FL5
• 2023+ Acura Integra Type S DE5

Once this kit is installed, the Honda HUD and LogR oil temperature readout becomes a simulated value and should not be trusted - HEL's own testing used a standalone SPAR gauge mounted directly in the sandwich plate for true oil temperature readings.

_______

HEL bought their own FL5 to develop and test this kit under real track conditions at Castle Combe (UK), and the result keeps oil temps roughly 20°C lower across the board. After 3D scanning the front end, they landed on the left side of the grille area - direct airflow, with zero impact on cooling to anything else.

A 16-row Setrab Series 6 ProLine oil cooler balances minimal pressure loss against real cooling capacity. HEL's Multi Angled Billet Thermostatic sandwich plate mounts at the front for extra clearance around the oil filter, with two spare ports for temperature/pressure sensors if you want them, set to open at 92°C (197.6°F) - hot enough to let the engine warm up safely, but responsive enough to start cooling exactly when needed.

The kit ships pre-assembled with high-flow AN10 HEL braided hoses, anodized aluminum fittings, and all brackets using OE mounting points - no drilling or car modification required. Abrasion-resistant heat-shrunk sleeving on the hoses also helps cut down on rattle and noise.
