Show original supplier description
The CSF 7095B is a 2-Row 42mm Race-Spec Radiator engineered for Subaru WRX and STI models from 2008-2021. It boasts CSF's exclusive B-Tube technology, which offers a significant improvement over standard oval tubes by using specially engineered tubes to increase surface area contact and heat dissipation. The radiator features ultra-efficient 6.5mm tall fins with a multi-louvered design, maximizing surface area for superior cooling. Constructed from 100% all-aluminum with TIG-welded end tanks, the CSF 7095B is built for high-performance applications and track use. It includes CNC machined mounting brackets for a true "drop-in fit," requiring no modifications for installation. Each unit is individually leak and pressure tested to ensure quality. It is not compatible with 2022+ WRX models. Additionally, it will not fit a 2021 WRX if equipped with a Grimmspeed FMIC and a Perrin oil cooler. The radiator has a black finish for a stealth look and comes with a 1.4 Bar (20psi) high-pressure radiator cap and a 2-year limited warranty.
