N and S Series MILVS V.1

The MILVS V.1 extracts hidden power from your BMW's valvetronic system with precision-machined supports that deliver +1mm intake valve lift and 3° additional duration. Your engine breathes deeper, pulls harder, and responds instantly across the entire RPM band.

Performance Gains

Expect immediate improvements in throttle response and linear power delivery from idle to redline. On turbocharged applications like the N54 and N55, you'll see faster spool-up and the ability to sustain higher boost levels without the typical valvetronic restrictions. The S55 M-engines benefit from enhanced high-RPM breathing and sharper throttle transitions. Power gains scale with your supporting modifications — naturally aspirated builds see 8-12hp gains, while boosted applications can leverage the improved airflow for significantly more.

Installation & Supporting Mods

This is a valve cover removal job requiring basic hand tools and about 2-3 hours in your garage. The precision-machined supports replace the factory valvetronic components — no permanent modifications to your engine. Works exceptionally well with intake and tune upgrades on boosted applications.
