Are Acura parts the same as Honda? Many are, and the VIN decides

Are Acura parts the same as Honda parts by design?

Honda established Acura on 27 March 1986 as its luxury brand for North America, and today Acura sells in the United States, Canada, Mexico and Panama. From the first Integra onward, much of the range has been built from Honda platforms.

Honda EPC carries both brands, and a Honda part number has three blocks. The middle block carries the model code, so on a shared platform an Acura and a Honda often show the same number for the same component. Our Honda EPC guide explains how to read each block.

Verified Acura and Honda pairs

These pairings come from the platform and engine records for each model:

• Acura Integra and Honda Civic: the fifth-generation Integra (DE4 and DE5), reintroduced for the 2023 model year and built in Marysville, Ohio, is built on the platform of the eleventh-generation Civic. The earlier ILX was based on the Civic platform too.
• Acura TLX and Honda Accord: the first TLX (2015 to 2020) sits on Honda’s D-5 platform with the ninth-generation Accord and used the K24W7 four-cylinder and the J35Y6 V6. The TSX before it was a rebadged European and Japanese Accord.
• Acura MDX and Honda Pilot: the first MDX (2001 to 2006) was derived from Honda’s global mid-size platform under the Accord, TSX and Odyssey and used the J35 V6. The third MDX (2014 to 2020) shares the GLTP2 platform with the Pilot, Passport, Ridgeline and North American Odyssey. The fourth MDX (from 2022) is on PF7 and related to the fourth-generation Pilot, with the 3.5-litre J35Y5 V6.

Where Acura goes its own way

The second-generation TLX (2021 to 2025) moved to its own platform, with a front double-wishbone suspension and an electric brake-by-wire system. It uses a 2.0-litre K20C6 turbo four, and the Type S has a 3.0-litre turbo V6.

That makes the model name a poor guide. A 2020 TLX and a 2021 TLX share a badge and sit on different platforms, so decode the VIN and note the generation before you compare any part with a Honda.

Which parts cross and which stay Acura

On a shared platform, engine parts, filters, gaskets, sensors, hubs and suspension hardware cross most often, especially where the engine code matches. A J35-family V6 in an MDX and a Pilot of the same generation is a strong lead for service parts.

Grilles, lamps, bumpers, badges, seats and interior trim are Acura’s own. Audio, navigation and body modules can differ by trim and market as well, and a replaced module may need setup with diagnostic software, which sits outside the parts catalog. Order the module by VIN and plan the setup as a separate job.

How to check an Acura part against a Honda by VIN

Decode both VINs in the free VIN decoder to confirm the model year. Then open each car in its catalog, the Acura catalog for the Acura and the Honda catalog for the Honda, and find the same assembly on both diagrams.

Compare the full part numbers. If they match, the part fits both. If only the first block matches, you are looking at the same kind of part for a different model, so treat the two as different parts. Record the confirmed number on the job card next to the VIN.
