If I may add something. Sameer is correct that oem have no competitor even morimoto don't stand a chance (I even confirmed with Matt from TRS) but problem is you are never certain what u getting under the hood of the ballast. Here is proof. I almost went thru with a deal from a chinese vendor who claimed to sell oem denso but stopped short.

Fake denso

So preferred to spend some extra buck to be certain to get actual oem.
@Ausl is correct too coz morimoto complete retro kit from TRS is good in it's own class. U get peace of mind that what u get would be real. One thing is certain TRS also get their stuff from china.
