Set of 24 studs and nuts (48pcs total)

Genuine BMW studs with an E-Torx end for easy installation and removal

Standard thread size - no need to upsize even with forced induction

Copper plated vibration-proof nuts

Also available with or without M50/M52/M54 exhaust manifold gaskets - These are high quality steel/composite gaskets with fire rings, not the cheap short-lived aftermarket units. We use them on all of our M5x turbo builds.
