CSF Nissan R33 Skyline GT R GTS Full Billet Aluminum High Performance CSF R32 Nissan Skyline GT R GT S Full Billet Aluminum High Japspeed Nissan Skyline R32 GTST GTR 87 94 Aluminium Radiator Test Fitting CSF Toprank Radiator in an R33 GT R Skyline GTR USA Evasive Motorsports: CSF Racing x TopRank Full Billet Aluminum Radiator. The 2 Row 42mm core greatly not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSFs Exclusive B Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super efficient multi louvered fins maximize airflow through the core for the best possible performance. More cooling rows also improve the overall efficiency of the radiator. More cooling tubes means more surface area for the coolants heat to dissipate from. Each end tank is constructed from high grade aluminum for strength and durability. The TIG Welded construction further increases the overall strength. Each top end tank includes a pre plugged 1 8th NPT and each bottom end tank includes M16x1. 5P ports for temperature sensors. The CSF radiators mount in the factory location and require no modifications or cutting. Each radiator includes a 1. 4 bar high pressure cap with an embossed CSF logo. High pressure radiator caps raise the boiling point of coolant. This helps protect the system from boiling over at higher operating temperatures. While the radiator is designed to keep the system from reaching such temperatures, it is always good to have extra protection for situations where the coolant gets too hot. 2 Row 42mm Ultra High Performance Core 75 Cooling Tubes with CSFs Exclusive B Tube Technology 6. 5mm Tall Ultra Efficient Fins with a Multi Louvered Design for Maximum Surface Area Contact CNC Machined Mounting Pins and OEM Style Inlet Outlet 1 8th NPT Temp Sensor Port on Top End Tank M16 x 1. 5P temperature sensor port with pre installed plug 100% All Aluminum TIG Welded Construction 1. 4 Bar High Pressure Radiator Cap with CSF embossed logo True Plug and Play Drop in Fit Installation Requires Absolutely No Modifications Individually Leak and Pressure Tested OE Location Fan Shroud Mounting Points 2 Year Limited Warranty Applications: 1999 2002 Nissan R34 Skyline GT R (incl.
