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.

This is an awesome toy for dogs and cats!
Color: red
This is such a cool toy for a dog or a cat. I bought it for my 28 pound Aussie doodle. She’s slightly laid up after an injury recently so I’m trying to come up with things she can play with in the house without excessive running. This totally keeps her engaged and she loves it. But I have to watch her because every once in a while she’ll just catch it and try and chew on the ball! But I’ve been sharing it with my neighbor who has a cat. She’s borrowing it today and her cat loves it too! It seems pretty durable overall but it certainly doesn’t want my dogs’s jaws trying to crack it into. You do hear a humming noise while it’s running but I think that’s to be expected. Mostly I just love how much it entertains both dogs and cats!!

Nice Idea But Won't Last With A Frenchie
Color: orange & blue, Color: orange & blue
My dogs loved the balls, however, withing 30 minutes, they were in pieces. Be careful because these parts can become choking hazards. Maybe they should try to make them a bit more sturdy, then I would buy again. Wish I could give them more stars because I liked them and the dogs did too.

Great concept not great product.
Color: red
It worked great for the first 20 minutes in the first day. Now my dog gets it and runs with it in her mouth and there’s no more chase. She also ripped off the flap that hides the USB port on day one. Today is day two and I think I want to return it but she still loves it. I’d only use with supervision though bc it’s already falling apart. She’s only 10 months old and a 9 lb multipoo.

Not a chew toy
Color: red&green
Our dogs love these! The dogs play for about a half hour then they get tired ,they pick it up by the string and toss it around , only important thing, supervise play time !!! This will break if chewed on , this is not a chew toy , put away once your dogs are done with it .

Not durable
Color: red&green
The description says for cats and dogs. My 6lb mini poodle tore it up in less than 40 minutes. The red one worked but the green one wouldnt even turn on. The indicator said it was fully charged but u plugged it in for a short time but nothing. I dont know if i can get a refund or not since the cover on the red one has been completely torn off. I dont recommend this product
