Dont be fooled by other high-performance aftermarket options that utilize the OEM plastic rock guard. The OEM rock guards vertical channel design is specifically designed to only work with the tube spacing found on the OEM core. When the OEM rock guard is installed on an aftermarket radiator, it actually blocks a significant amount of surface area. Obviously this is detrimental to the intended performance. During CSFs own R&D phase, CSF analyzed both the OEM and other aftermarket offerings and decided to go the extra mile. CSF redesigned the included rock guard to allow maximum flow to the radiator core, while still offering ample protection from small rocks and road debris all proven on CSFs in-house wind tunnel.

CSFs new Auxiliary Radiator fits both the left and right side of the vehicle as a drop-in fit. Thus requiring no modifications to install. Each features CNC machined mounting brackets and OEM style Quick Connect inlet/outlet connections. This makes for a true plug-and-play installation that does not interfere with aftermarket performance aero modifications.

My water kettle just stopped working after a year. Once I boxed up and returned the kettle, Asurion refunded my account.

All Gotchas, Gimmicks, and Grief
My husband broke the item in question, which was a Chemex coffee maker made of nothing but glass. It shattered full of coffee, so like a normal human he cleaned up the dangerous mess and threw it away. I put in a claim, and it said that I had to ship back the product. Believing that the Asurion process was as simple as stated, and reading the agreement that does mention that sometimes they'll require shipment of the item, but that they will review cases and use reasonable judgment, I contacted their chat, explaining that the requirement that I mail them a wet pile of shards of glass soaked in coffee (and a little bit of blood) was unsafe and unreasonable. I don't even know how I could do that in a way that would be safe for the people opening the packaging, or even to take it to the store. The shards of glass might puncture any plastic, and the wetness would soak through, plus there's the biohazard issue. Seems silly for a $47 product replacement to me. I figured any human would understand. First chat associate closed my case without even responding to me. I had to reopen it. The second one told me, "Yes, that is how your warranty works" as an answer to my "Hello, the last chat closed without me talking to anyone." I tried to explain the situation, and was told "If you call the hotline, maybe they'll help you." I call the hotline. The first person tells me tough, I have to mail it. I say it was thrown away. He says "AHA then it's lost! Your warranty doesn't cover lost things!" I say no, it's not lost, it was disposed of properly as shards of glass should be. I finally ask can I speak to someone else or a supervisor. He lies and says yes. I sit on hold for 20 minutes, never any wait time or any sort of indicator of when someone will talk to me. The phone call quality finally gets very horribly staticky, so I hang up and try again. Hallelujah, I get a decent human being who immediately says, "Oh, no, that's not reasonable! That is an unsafe thing to have to mail. I'll send it to the override department who should approve this because it's obvious that's not a normal thing to expect." Today I get an email that says: We can't approve your claim. We reviewed your NO SUPPORTING MANUFACTURER COFFEE MAKER claim. The product in your claim is not covered by your plan. As a result, we're unable to approve your claim. Nothing about the requirement to mail a biohazard, just the item isn't covered even though the item is absolutely covered. While I understand that loss prevention is important, this is a very small potatoes return and it isn't like I made this up. It would be easy to make me happy. I'm sure it has cost them more money to deny it than they would have lost covering the Chemex. I've bought multiple of their product replacement policies before. I never will again. They didn't offer for me to send a picture or anything. They just wasted hours of my time and sent a clearly AI-based answer, rather than treating me like a valuable customer.
