The rubber vacuum hoses are used in a number of applications and are prone to cracking. Over the years, the engine temperatures and weather conditions can take their toll and either weaken or cause breaks in the vacuum tubing. Your engine will run rough and set the check engine light due to vacuum leaks. This coupling hose connects the breather tube to the valve cover port. Part number: 06D133299C
