I really did not want to drive back again (they messed up my service the first time with incorrect fluid weight so I already had to go back to get that corrected)

So I just went online and bought 1x 40703-JA00A.

After the fact I did a little searching against my year and model and it said that part was not compatible, and the compatible part was 40703-JK00B.

I would think they are all compatible as it is just a valve stem cap.

The 40703-JK00B is $11 more than what I bought 40703-JA00A for.

From pictures they look the same, are there any real differences between these part numbers, maybe different threads or something else? Or are they all the same and just keep the 40703-JA00A even though Infiniti says it is not compatible but 40703-JK00B is. ]]> General Tech Questions mjnoles1 https://www.myg37.com/forums/general-tech-questions/305697-tpms-sensor-cap-differences-between-2-part-numbers.html https://www.myg37.com/forums/general-tech-questions/305685-2013-infiniti-g37xs-sedan-w-40k-miles-fluid-changes-sensible-or-stupid-new-post.html Sat, 18 Apr 2026 19:17:29 GMT Was this smart or stupid?

First, please please do not say if you did it myself it would only cost X, I promise you I still would not do it.

Here is what I did today at my local Nissan dealership, and I decided to go back next week to finish it off.

Today:
Oil Change
4 wheel alignment
Braking fluid flush and refill
Rear Synthetic Differential Service with installed limited slip additive
Front Synthetic Differential fluid remove and refill
Total Price= $925.17

Next Week:
Coolant Flush and Refill
PS Flush and Refill
Total Price: $437

Total between Today and Next weekend: $1362.17

Two questions:
1) Was the above services a smart move with my car being 13 years old (even though it only has 40k miles)?
2) Was the above prices reasonable at a Nissan dealership?
