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. ### ⭐⭐⭐⭐⭐ Yes buy+++++ *by D***C on Reviewed in the United States on February 25, 2021* Great --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/148637978-ptnhz-universal-aluminum-50mm-blow-off-valve-dump-valve-bov](https://www.desertcart.hr/products/148637978-ptnhz-universal-aluminum-50mm-blow-off-valve-dump-valve-bov) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-15*
