95 Pathfinder Exhaust Stud

[Jimmie]

Is the factory size M10 x 1.50 x 52mm ? What is the improved version ?

The improved version are turbo studs from a 300zx. I can't remember the thread pitch at the moment.

They are M8 x 1.25. I used 30mm grade 5 bolts with a flat washer and lock washer. Perfect length on my aftermarket headers. Everything from Nissan was special order and I didn't want to wait for it to come in. Bolts work fine, however studs are nice for lining up your manifold.

 

I just did mine and used this thread for info, however some of it may be incorrect.

One of the posters in this thread posted up this info

 

PN 14037-V5005 - Lock Washer

PN 14039-W1500 - Nuts

PN 14065-V5004 - Manifold studs

 

They also posted up 40mm bolts as an option, which may work on factory manifolds with the thick washer, however they bottomed out before tightening up on aftermarket headers with thin flat washer and locks.

 

When I gave these part numbers to my local dealership they told me these studs are for a 95 quest. Are they the same as the turbo 300ZX? No idea, but either way they were special order.

 

I hope this helps, I know I got tired and searching threads and went for the first info I could find.

Yes and yes. My Thorley headers are held in with bolts as well....

Any aftermarket exhaust stud in the right size will work fine. You don't need to buy the turbo 300zx studs. The ones I got at napa worked just fine.
