Product Information

THE ULTIMATE COOLING SOLUTION FOR THE F-SERIES N55 ENGINE


Push your N55 powered F2x, F3x hard enough at the track and you'll know all too well about the buzz-killing oil temperature limp mode. The stock engine oil cooler is not sufficient at the track - temperatures skyrocket, oil deteriorates and limp mode is entered. Once limp-mode is entered you need to reduce the load on the engine to lower the oil temps. 

With the CSF Race-Spec oil cooler say goodbye to nursing your car around hot oil temps! The cooler, tested in excruciating 46C temperatures, has been proven to lower your BMW out of the oil temp limp mode and bring the fun back! 

Direct replacement for BMW part number 17217618360.

Beautiful Purse but could be better
Color: Denim Blue
I ordered this bag without reading the reviews. I actually read them after I ordered it and it arrived today. After receiving the product I do agree with some of the other reviews. I REALLY wanted to give this five stars but I didn't like that the purse was shipped in a sealed vacuum bag which flattened the purse and put it in a purse bag. I do love the leather, material, and style of the bag. I also love that it is a great size. I also think the price is a little expensive considering that the purse is out of form and placed in a plastic sealed bag. Because I've always wanted a denim hobo style type bag I decided to keep it and I ordered a purse insert which cost me another twenty plus dollars so that when I wear the purse it won't tip over when I sit it down.
