The radiator was packaged with excellent care and design. Fit right in my 04 RSX no problem however the I had some trouble aligning to fan bolts to the radiator. All and all an easy conversion.

Oem fitment

Bought this radiator mainly because my OEM one started leaking and since Iím going to track this soon might as well upgrade. The quality of this is top notch. Clean welds and quality materials. It slid right in with no issues whatsoever. You can use mishimotoís fans or OEM. I stick with oem since the were still working. Car has better cooling and Iím sure this will last years to come.
Great Radiator
