### ⭐⭐⭐⭐⭐ 







  
  
    Works well.
  

*by P***T on Reviewed in the United States on January 12, 2021*

Got this for a BMW 335i N54. It was this or the Tial BOV which was almost $300, I figured I would try this at a near 90% discount and if it did not work then I would go for the brand name deal. So far so good, seems to look, sound, and perform like a legit BOV.  Will update if anything changes.

    N54 upgrade
  

*by M***Z on Reviewed in the United States on October 11, 2021*

I used this for my 08 535xi. I installed a new charge pipe to go with my JB4 upgrade. The N54 should have an 11lb blowoff valve, so I simply used the 18lb spring and cut the extra coils off. It's an evenly wound spring, so it really is just that simple to change the spring rate. I believe it was a 9 coil spring, so it's just a matter of cutting 3.5 coils off of it.I have about 2k miles on the BOF and it's worked flawlessly so far.
