My Buying Guides on 2013 Infiniti Jx35 Alternator Replacement
Why I Replaced the Alternator

I learned that not every alternator labeled “fits JX35” is the same, so I made sure the part matched my vehicle’s engine and electrical requirements.
OEM vs Aftermarket Alternator
I had to decide between an OEM alternator and an aftermarket one. The OEM option felt safer because it matched the original part more closely. However, aftermarket alternators were often less expensive.
From my experience:

I chose based on my budget and how long I planned to keep the vehicle.
