The 2026 Nissan Altima shipped with a single engine — the 2.5L L4 — which keeps fitment straightforward: all 199 parts listed for this model year are matched to that configuration. What still deserves attention is the notes column on each part, where position (front/rear, left/right), trim and production-date qualifiers live.
Every part across the 12 categories shows its brand and manufacturer part number. Use the number to cross-reference: match it to the part coming off the vehicle, compare an OEM-supplier part against its aftermarket equivalent, or verify a shop's estimate line by line. When a number is discontinued, the same-fitment parts around it are the fastest path to a current replacement.
