M20 Exhaust Manifold Nut Set

Copper exhaust manifold nuts for the BMW M20. Copper is the correct material for exhaust fasteners — it resists seizing at high temperatures and comes off cleanly on removal, unlike steel nuts that weld themselves to the studs over time.

• 12 nuts — manifold to cylinder head
• 6 nuts — manifold to downpipe
• Full set for both M20 exhaust manifolds

The nuts we use on every M20 exhaust manifold install at BimmerHeads.
