Koyo 93-95 Mazda RX-7 1.3L Turbo N-FLO (Dual Pass) Radiator

Koyo 93-95 Mazda RX-7 1.3L Turbo N-FLO (Dual Pass) Radiator

Key Specifications:

• Core Series: HH Series "Hyper Core"
• Core Thickness: 48mm (nearly double the OEM thickness)
• Flow Design: N-FLO Technology (Dual Pass). This internal partitioning forces coolant to pass through the core twice, increasing heat dissipation by up to 35% compared to standard single-pass radiators.
• Construction: Fully TIG-welded aluminum with Nocolok brazing for maximum durability and vibration resistance.

Notable Features:

• Direct Fit: Retains all factory mounting points for the fan shroud and coolant hoses; no drilling or cutting required.
  
• Sensor Port: Includes an integrated 1/8" NPT female fitting (with plug) for easy installation of aftermarket temperature gauges.
  
• Billet Filler Neck: Precision-machined for a superior pressure seal and longevity.

Critical Notes

• Radiator Cap: The factory cap will not fit. You must use a Koyo SKC-13 or equivalent deep-plunger racing cap.
  
• Transmission: Designed for Manual Transmission (MT) only. Using this on an automatic RX-7 requires an external transmission oil cooler.
