NEW, updated design allows for more applications! The TMS Oil Cooler Fitting kit allows much more flexibility in the routing of oil cooler lines. Standard oil coolers utilize �hard lines� which can cause fitment issues for cars with superchargers, Accusumps, or other aftermarket performance parts. Our kit replaces the oil cooler hard lines with two TMS engineered -10 AN fittings, mounting bracket, and O-rings. Flexible braided hoses can then be run to the oil cooler which eliminates routing issues from supercharges, intakes, and other components. The brackets are CNC machined stainless steel and the -10 AN fittings are lightweight aluminum.

BMW's newest high-performance powertrain—the S58B30—has proven to be an extremely durable platform built to last! Unfortunately, its factory oil cooler location is an egregious weak link in an otherwise bulletproof oiling system. Positioned just inches above the ground, the engine oil cooler is vulnerable to damage from debris, potholes, parking blocks, and other unavoidable road hazards. A single impact has the potential to rupture the cooler’s delicate aluminum fins and tubes, resulting in rapid oil loss and catastrophic low oil pressure. The only factory protection for this part is a flimsy undertray.
To safeguard the oil cooler, we've engineered a high-strength Aluminum Skid Plate for the F97 X3M and F98 X4M. Designed for peak performance and protection, our skid plate acts as a shield, preventing damage to the oil cooler while maintaining proper cooling efficiency.
Crafted from 4GA (4.83mm) 5052 aluminum, our skid plate delivers a perfect balance of strength and weight savings. Unlike the fragile factory plastic belly pan, our design forms a protective barrier from the front bumper to the front subframe, shielding your oil cooler and other fragile componentry from unexpected impacts. Its sturdy one-piece design enhances underbody rigidity without adding unnecessary weight over the front axle.
At Turner Motorsport, we believe protection shouldn't come at the cost of performance. Our engineers aimed to outperform the factory undertray design with laser-cut air channels that optimize airflow through the oil cooler. While located under the engine, the oil cooler receives its fresh airflow from the front air dam. Air flows through the lower front grille, into the oil cooler core, and out of the skid plate. The factory belly pan allows air to bypass the core, leading to inefficient cooling and mediocre airflow at speed. Our design allows for efficient heat dissipation by incorporating flared air channels, which guide cool air through the oil cooler and deflect road debris before it can reach the fragile core.
Upgrade your F97 X3M or F98 X4M with the Turner Motorsport Aluminum Skid Plate for added protection, durability, and performance.

The TMS E36 Stage 2 Oil Cooler Line Upgrade Kit is an ideal alternative to the factory oil cooler lines, with multiple added benefits. In combination with our TMS AN-10 Oil Line Adaptor Kit (Part # TEN9910200), installing the TMS E36 Stage 2 Oil Cooler Line Upgrade saves you time and money. Unlike factory lines, the TMS E36 Stage 2 Oil Cooler Line Upgrade can work with vehicles equipped with superchargers or racing alternator pulleys. The TMS oil cooler lines now sit safely away from any moving parts like pulleys and serpentine belts. Our lines are made from HTP (High Temperature Polymer Braided), a synthetic line with multiple advantages over rubber or stainless lines. 
CSF is one of the premier cooling product specialists available on the market today. One item that is often overlooked is the oil cooler. Luckily CSF has taken up the task of upgrading the oil cooler as well. If the oil runs too hot, it can lead to a reduction in wear protection and damage to the head, block, or the turbo system. This unit has 17 cooling tubes in the front with anther 6 in the rear of the cooler and still fits in the stock location without any issues.
