Spectra 4401-3517 Premium Turbocharger Intercooler Charge Air Cooler

The Spectra Premium 4401-3517 is a direct-fit replacement turbocharger intercooler (charge air cooler) engineered to restore proper thermal management in turbocharged diesel applications. By cooling compressed charge air before it enters the combustion chambers, this intercooler increases air density, delivering improved power output and engine efficiency.

Spectra Premium intercoolers are engineered, developed, and validated by an in-house team of Canadian engineers to meet the cooling efficiency of Original Equipment (OE) specifications. Each unit is designed to minimize pressure drop and maximize heat dissipation for optimal engine performance.

Key Features:

• OE-matched cooling performance — engineered to meet or exceed original equipment specifications
• Minimized pressure drop — optimized internal flow design maintains boost efficiency
• Maximum heat dissipation — effective charge air cooling for improved combustion and power
• Direct-fit replacement — designed for exact fit, form, and function for straightforward installation
• Premium construction — built with quality materials for long-lasting durability
