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.

Get a longer launcher. This only throws 30 ft
Size: 1+3pack
Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

These are dog tested and approved.
Size: 1-pack
The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend
