Product Details

The CSF 3989 is an upgraded O.E.M.-style replacement radiator featuring an aluminum core with plastic tanks. Engineered to exceed original equipment performance, this cross-flow radiator uses a 30mm core — 7% thicker than the OEM 28mm spec — for improved thermal capacity and cooling efficiency. CSF has manufactured radiators to high-performance standards for over 50 years, with each design carefully engineered and wind-tunnel tested for cooling performance validation at ISO/TSO certified facilities.

Key Features:

  • Aluminum core construction with plastic tanks
  • Upgraded thicker core: 30mm vs. OEM 28mm (7% thicker)
  • Cross-flow design
  • Single-row core
  • Core dimensions: 22 15/16 in. (L) x 21 11/16 in. (W) x 1 3/16 in. (thick)
  • Inlet: 1 13/16 in. diameter, right-side position
  • Outlet: 1 3/4 in. diameter, left-side position
  • No integrated oil cooler
  • Radiator cap not included

This CSF radiator delivers a direct-fit, drop-in replacement experience with enhanced cooling performance over the factory unit. Built to the same rigorous standards trusted by OEM suppliers and performance enthusiasts worldwide.

Ordered Enkei brand hubcentric rings, company sends Coyote brand hubcentric rings. Will they work, yes but it's a classic bait-n-switch sales tactic. Wish THMotorsports was upfront & honest with their customers.
