Market specification is one of the least understood reasons a part fits one customer's car and not another's. Two cars can share a chassis code and a model year and still leave the factory with different emissions equipment, different sensor counts and different front-end packaging.
US, EU and JDM builds of the same platform frequently carry different catalyst configurations and different oxygen sensor arrangements. That determines how many sensor bosses a pipe needs, where they sit, and whether a part aimed at one market leaves the other with an unequipped port or a sensor that cannot reach.
Cooling pack depth, radiator support brackets, bumper ducting and headlight structures can all differ between markets. That is the layer that decides whether an intercooler or a front-mount intake drops straight in or needs trimming to clear.
Tell us where the car was sold, not just where it is now. A JDM import living in Germany needs the JDM configuration, not the EU one. If you are not sure which specification you have, a VIN resolves it, and photos of the engine bay and the existing part will usually let us tell you.
On a turbocharged platform the intake and charge path is where market differences bite hardest, because that is where the sensors live and where packaging is tightest. On a naturally aspirated car the differences are usually smaller, though they do not disappear.
Chassis code, build year and market in one message is the fastest route to an answer. Browse by platform on our Shop by vehicle page, or send the three details and we will confirm against the right configuration rather than the closest one.
