International Intercooler - Spectra Premium 4401-3528, Active Radiator Supply Company NAV16401, Serck FLX010703, Reach Cooling 61-1209

When your International 9600 or 9700 needs a new charge air cooler, the Reach Cooling 61-1209 is the aftermarket direct replacement built for the job. This intercooler replaces Active Radiator Supply Company NAV16401N, Spectra Premium 4401-3505, Serck FLX010703, Keystone Auto Industries HDH010300, Cancore Industries CAC129, and Vista Pro 441185, making it straightforward to confirm you are getting the right part. The aluminum core features harmonica-shaped tubes with a minimum flat tube wall thickness of .55mm to handle elevated boost pressure, while a deep extrusion header creates a stronger tube-to-header joint that holds up against vibration and thermal cycling. Headers are reinforced with aluminum bronze to boost strength by 50 percent, and a wider-angle header plate bond eliminates the risk of header cracking under repeated heat cycles. Each unit ships in a 7-layer corrugated box so it arrives ready to install. Fitment covers 1991-1996 International 9600 and 9700 trucks across the 10.0L, 10.8L, 11.1L, 12.7L, and 14.0L engine applications. If you are sourcing by cross-reference, this unit matches NAV16401N and the other interchanges listed above, so you can drop it in as a correct-fit replacement and get your International back on the road.
