NTN and NTK are OEM suppliers for Subaru, and these parts will come from one of those two suppliers. This wheel bearing kit is likely made up of the very same Japan-made parts you'd get from the dealership. It just costs a good bit less.
You get one front wheel bearing, plus two bearing seals. Order two kits to do both front wheel bearings.
Fits all 2002-2007 Subaru WRX & 2004 STI
