Tuner S54 Silicone Crankcase Vent Hose Repair Kit – E46 M3 Z3M

Product Details

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition. Replace the brittle or broken line that attaches between the oil separator and air box. Our Turner Silicone Crankcase Hose can be used in place of both the standard and CSL intake boxes.

Our engineers at Turner sought out to solve the degrading issues that happens with the factory crankcase vent hose and found the best solution is a silicone replacement. Our Turner Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to prevent vacuum leaks and lackluster performance. Simply take your factory crankcase vent hose and remove the ends; the factory ends can be installed on the new Silicone Vent Hose with the supplied clamps for a tight seal.
