The NRW Design S65 Billet Block Off Cap is a two-piece billet cap for sealing the intake elbow when removing the secondary air pump, and is also suitable for supercharged S65 engines.
An inner Viton O-ring and an upper locking cap combine to give a tight, long-lasting seal, and the anodised black cap fits in under a minute.
Please note: For off-road and race use only. Billet block off plates are sold separately.
