## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works as intended
  

*by G***A on Reviewed in the United States on 12 May 2022*

Works good and no more oil leak.I also recommend buying a rear main installer tool.  The only one I found online was from ASF Machine in Colorado.  It presses the seal to the correct depth.

### ⭐⭐⭐⭐⭐ 







  
  
    High Quality  - Great Price
  

*by S***L on Reviewed in the United States on 25 February 2022*

Changed clutch on our Subaru WRX and since we had it removed, decided to change rear engine seal which was a breeze.  AMZ shipped it promptly and was impressed for the price  - lot cheaper than local shops or the dreaded dealer.

### ⭐⭐⭐⭐ 







  
  
    Good alternative to OEM (Subaru)
  

*by J***P on Reviewed in the United States on 28 March 2014*

The seal I got was black and labeled NOK.  The OEM (Subaru) one is brown and listed NOK and has a long service life due to the Viton coating used.  So I am not sure if this is a rebranded Subaru seal, if Fel-Pro makes the seals for Subaru, or neither.  This installed just as easily as any OEM rear seal.  Make sure you lubricate the inner seal prior to assembly and use caution to avoid rolling the inner seal edges over.
