Hi guys, so I tried to replace my spark plugs today on my 2007 Infiniti G35X, but the screws on the intake were insanely tight, and I ended up warping the bottom right one.

I am thinking of getting a replacement screw, does anyone know what part number it is and how much it costs? Also, anyone know a proper way to get at it?

 

I believe those are allen screws. Not sure about size though.

 

Metric

 

Most of our car is held together by M6x1.0 boats. They have a 10mm head or 5mm metric Allen size head.

 

Okay cool I will go look for some at Home Depot or Canadian Tire. Hopefully they have some

 

I think Nissan stocks them as well. Be sure to properly torque them when you reinstall, someone probably cleaned the TBs in the past and didn't torque them.

 

Loosen in reverse order, tighten in numerical order

 

Where you able to replace your spark plugs? or are you getting those throttle body bolts first? that driver side didn't look to clean to me, if someone tried to previously clean them, they should not have been that tight! that one or two where ruined, removing them, imo....

 

You circled the threaded insert. Is that what you damaged ?
