Installing the OEM exhaust manifold studs can be a real pain. Since the stock studs do not have a drive end, you need to "double nut" them on and off, which can be time consuming and tricky. Our upgraded exhaust manifold studs come with a torx drive end to easily install them into your BMW cylinder head. Make sure to apply a little bit of oil onto the threads so they turn in easily. A must have upgrade for any bmw owner.
