Yes. Every steering part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What should I replace at the same time?
Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2003 Acura NSX was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2003 Acura NSX?
First match the engine — each row shows which engine(s) the part fits. Then flush old power-steering fluid when replacing a pump or rack — grit in the old fluid is the number-one cause of repeat failure. The notes column carries position and trim qualifiers where they apply.
