Rock Guard: CSF knows the kind of punishment the front of a car can take on or off the track. The wrong bit of debris flying through the front grille can quickly punch a hole in a cooler. Because the Transmission cooler sits at the very front of the center cooling stack, it is quite vulnerable to damage. The factory grille is the only form of protection for the OEM transmission cooler. However, this still isn't the level of protection many race teams and enthusiasts are comfortable with. To address this concern, CSF has incorporated a rock guard to keep your cooler safe and your X3M/X4M running strong in the event of debris making it through the front grille.
CSF combined the Heat Exchanger and Transmission Cooler into a cooling module that comes as a single unit. The combination not only solves two cooling issues for the X3M and X4M, but also lowers costs which are passed along to the customer.
The CSF #8331 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.
