I've have read countless posts of people grounding the Throttle Body and I've been trying to find a picture of the actual TB grounding points for a 5.5 gen, but have not been successful. I'm considering the points circled in Green and Red (or Yellow) in the picture below. Anybody has a better option? Is this not really a good idea to begin with?

EDIT: I'd like to know which spot was selected as the grounding point on the Throttle body.

 

Any reason for grounding? Going with an 09 TB?

 

Those black points on the fire wall are rubber covers and the windshield wiper assembly is behind there, so I'd be careful. If you look on the fire wall down a bit further directly behind the throttle body, there is a stud sticking out with a nut on it. Use that for your ground point.

 

Just grounding the TB as part of a grounding kit.
No plan to go with an 09 TB; any reason I should?

Edit (I didn't even know one could use an 09 TB on a 5.5 gen).

Thanks. Those rubber covers are just plugs for threaded holes, similar to the one found closest to the fender, on the driver side strut tower area.
I noticed the stud sticking up down below, which I could use, but the threaded holes, right next to the VIN placard, are just a shorter run.

 

What's the point of this?

 

I kept reading about people claiming to experience improvements in different areas, with a fresh and more robust set of grounding connections for various engine components, such as starters, alternators, and throttle body.
Following directions from Active Tuning, I made a grounding kit and istalled it on a previous 2000 Maxima GLE and felt differences, such as smoother idling, faster starting and slightly brighter lights.

Still trying to find out if anyone actually grounded the Throttle Body as part of a grounding kit, and which one is the actual contact point on the TB.

 

I'm sure any bolt on the TB will do just as fine as the other. You could even use bolt on the elbow of the manifold.


OT: I tried searching for 09 TB and couldn't find anything. Is it a direct swap? And what does it take to do the swap if it isn't direct. I am very interested.

 

[16298M] CHAMBER ASSY-THROTTLE

Maxima (A35) 16119-A35001

2009+ Price: $555.73

From courtesyparts.com

This is correct right?

 

Interesting; I went to that site and noticed that the SKU number for the assembly of the 2009+ is different than the one for the 2002-2003, (16119-A33B005 for the Maxima A33B), but the Code Number for the actual part (16298M) is the same for both.

Did you do that? If so, which one is you connecting point on the throttle? Did you feel any difference in throttle response, or anything at all?

 

I personally have not. But I might do something like this to help the stock grounds if there is anything wrong with them.

 

That's too expensive

 

Nelsito65 have you ever completed/attempted this Idea?

I wonder if it does anything? I would think Blehmco would have grounded this item in his kit if it did anything worth while?

we should ask Shinjiduo a member here who makes kits for many cars

 

I left the Throtle Body alone. I wasn't sure if it did anything worthwhile either. I do remember reading about other Org members doing that and wanted to hear it from one of them. I think Scottwax is one of those but I'm not sure if he is even around these forums anymore.
