Race-Ready Aluminum Cooling That Won't Quit
Crafted from premium aircraft-grade aluminum, the Pundimo radiator combines lightweight agility with serious heat-shredding power. Its patented tube-and-fin design packs 16 high-density fins per inch – 35% tighter than conventional radiators – paired with 3/8" optimized coolant channels that create 25% more surface area. The result? 40% faster heat dissipation and 1,500 additional cooling surfaces to tame even turbocharged engines, whether you're dominating lap times or crawling in summer traffic.
Engineered for Abuse, Built to Last
This radiator means business. The military-grade aluminum core shrugs off corrosion from road salt and harsh weather, while vacuum-brazed seams eliminate leak risks found in welded models. We've added 30% more coolant capacity to smooth out extreme temperature swings – think desert highways to mountain passes – and trimmed 5 lbs off the weight for better handling. No plastic end tanks, no flimsy joints – just clean aluminum engineering that handles curbs, vibrations, and years of daily driving.
Why Drivers Upgrade to Pundimo:
✔Tall 1-inch fins pull 18% more airflow at speed
✔Direct OEM fit – installs in 90 minutes with basic tools
✔Dense 14-16 FPI design outpaces basic aluminum units
✔Overbuilt core withstands 300+ HP builds
From weekend warriors to daily drivers, this is the smarter way to stay cool. Lighter than steel, tougher than plastic hybrids, and designed to outlast your ride – because when temperatures climb, compromise melts away.
