Hey guys! CSF radiator is running well after three years and summers in AZ. I put this one in at 59k miles and I'm at 65k miles now and no issues as of yet. There is some confusion between the brass and plastic style. I have the plastic OEM equivalent and I haven't had any issues with this one or the one I put in my last TJ.
That being said, I would probably go with Denso on my next one since they are an OEM supplier for many foreign vehicles. I have one on my Tundra (OEM) with no issues as well.
CSF has been fine for me and is a great option for $100. If it goes bad it's not hard to replace. Denso is a little pricier but has a long-term reputation of being reliable. It's a pick-your-poison kind of situation

Mine has worked out for me.
