Copper Locking Exhaust Nuts Suit Nissan Navara D22 with ZD30 engine. Suit Nissan Navara D40 Spanish and Thai models with the YD25 engine. This is a Set of 12 Nuts however the ZD30 and YD25 models only use 8. These are the nuts that are used for the exhaust manifold on a ZD30 and a dump pipe on the YD25 engine. We also sell the studs to suit separately in our online store. These need to be replaced when the manifold is taken off the motor as sometimes the nuts are stuck on, due to the studs going hot to cold etc. If you are unsure if this part suits your vehicle, please contact us with your VIN# to confirm for you.
