Vargas Extended M7 Port Head Studs - Pair - BMW B58/N54/N55/S55

Product Details

Reliability is paramount when upgrading your BMW's exhaust or turbocharger system. Standard M7 studs are notorious for being difficult to find in longer lengths, forcing many builders to compromise with hardware store bolts that can't handle the thermal stress of a high-performance engine. The VTT-FAB Extended M7 Studs are the professional’s choice for securing thick-flange manifolds on N54, N55, S55, and B58 engines. By increasing the long-end thread engagement to 24mm, VTT provides the necessary clearance to use high-quality copper locking nuts, ensuring your exhaust system remains leak-free even during aggressive track use.

Key Features

• Thick Flange Optimized: The 24mm long end is designed specifically for high-performance aftermarket manifold flanges.

• Integrated Hex Head: Unlike basic studs, these include a 5mm internal hex, allowing for precise torque without marring the threads.

• Direct Fitment: Designed to thread perfectly into the cylinder head without any drilling or tapping required.

• Sold Individually: Offers the flexibility to buy exactly what you need, whether you're replacing a single broken stud or doing a full 2-port conversion.

• Black Oxide Protection: Provides a durable barrier against the elements in the high-heat environment of the engine bay.
