use one of these types of search engines to find out right away if its a Nissan USDM part:
http://www.trademotion.com/par...14027 do a #2 search by part number. it will sometimes even tell you cars it finds the p/n compatible to.
i know for a fact the tensioner is USDM. the idler and the belt are not. you need to either order through some place like courtesy parts, superior nissan of puente hills, rbmotoring, etc.- ppl who can order jdm nissan oem.
