NRW Design Billet Spark Plug Tubes - BMW E90 | E92 | E93 M3 (S65)

Replace the ageing factory spark plug tubes on your E9X M3 with NRW Design’s fully serviceable billet alternative. Each tube is CNC machined from 6061 billet aluminium and sealed with replaceable Viton seals, so the seals can be renewed without replacing the tubes.

The design offers approximately 30% more sealing contact surface than the OEM tubes, giving a larger, more dependable seal – ideal when servicing or upgrading your S65 valve covers.

Please note: Supplied with a Viton gasket/seal set. Replacement O-ring kits are available separately.
