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.

Good if they fit
Special Size: Midweight, Size: 30W x 30L, Color: Dark Midnight Wash
The jeans are great, once I got the right size, but these I brought back to Whole Foods and got charged anyway because Amazon never got them back!! But cheaper than Levi’s

Important fit information
Special Size: Midweight, Size: 34W x 30L, Color: Tinted Medium Blue
Be aware that these jeans are loose fit, not fitted through hips and thighs. Excellent quality, well made, great value. But if you are not overweight, if you have a trim build you will NOT like these. They were very baggy and loose around my husband's butt and thighs, so we had to return them. However, if you have a more generous build under your size 34 waist you WILL like these, and the waist has some stretch. I removed one star for calling these fitted through hips and thighs. They're not.

Great fit and value for quality jeans
Special Size: Midweight, Size: 42W x 30L, Color: Tinted Medium Blue
For once I bought a pair of jeans that are super comfortable and feel like I’ve had them for years I had to return for a shorter size which was no problem and they now fit perfect Very good quality material like Levi’s or Wranglers not like inferior substitutes Great value for a quality product

Couldn't get the zipper button open!
Special Size: Midweight, Size: 38W x 30L, Color: Dark Midnight Wash
Returned. They are probably a good product but I have arthritis in my thumbs and it was excruciating to try to undo the button above the fly. I seemed like like the button hole was too small. Maybe a gorilla finished final assembly?
