Oem fitment
Kevin | April 30th, 2020
Bought this radiator mainly because my OEM one started leaking and since I’m 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 mishimoto’s fans or OEM. I stick with oem since the were still working. Car has better cooling and I’m sure this will last years to come.
Great Radiator

No problems with it. Ive had it installed for around a month. Excellent welding job compared to other brands. Easy to install of you know what you're doing.

I'll keep this short and sweet. This radiator is badass. Stock fan shroud bolts up nicely too.
Works and performs

Easy install, plug and play, purchased with the fan shroud for a sweet cooling combo. The Mishimoto fans are super loud but tats just the way I like it because I know they're doing their job.
