- Nissan Patrol GU with LS V8 engine & 4L60E or 6L80E automatic transmission
Note: Modification of the 6L80E transmission is required for the fitment of these headers. The lug on the left hand or passenger side of the transmission needs to be removed and ground back to provide clearance, as shown in the images below.
Note: Depending on how you are running the transmission cooler lines, the manifold block; MFG20256 may assist you in gaining clearance to things like floor and exhaust.
Note: Vehicles fitted with rear air conditioning will have to modify or make new air conditioning lines at the firewall.
