PRL Tube and Fin Intercooler Upgrade - 2023-2025 Honda Civic FL5 Type-R

Ultra-Lightweight CSF Tube-and-Fin Core

• Core dimensions: 7.25" × 4.25" × 28.2" (184 mm × 108 mm × 716 mm)

• Total assembly weight: 14.4 lbs (35% lighter than our 22.2 lb bar-and-plate)

• Faster heat transfer through thin-wall tubing, ideal for high-speed airflow and road-race environments

• Approximately 75% of bar-and-plate durability—still excellent for street use, but optimized for lightweight efficiency

Weight-Reduced Billet End Tanks

• CNC-machined from custom 6061 aluminum extrusions

• Sculpted internal geometry maximizes flow while removing every gram of unnecessary mass

• Final end tank weight: 1.05 lbs (down from 19.5 lbs in raw billet)

• Lightened mounting bosses and machined ribs for structural trimming and clean aesthetics

• Thinner-than-standard mounting flanges, secured with the included M8 socket-head bolts

OEM-Style O-Ring Sealing (Improved for Boosted Applications)

• Uses OEM-style O-ring grooves for reliable, consistent sealing

• Removes the factory assembly-tab groove known to blow out at elevated boost levels
  

Engineered for Maximum Efficiency

• Designed for high heat transfer, low pressure drop, and the lightest weight possible

• Perfect for drivers focused on road racing, endurance sessions, and overall cooling consistency.

Fitment

• 2023–2025 Honda Civic Type R (FL5)
