**DISCLAIMER - ONLY COMPATIBLE w/ motors with a functioning PCV! If Headports have been plugged, the VU Breather Cap will not function as intended because there will no longer be any vacuum in the crankcase.**
 
**Cross thread damage is not covered by warranty. Threads are tested before shipment to ensure threads are correct.**
 
**Fitment can only be guaranteed with OEM Valve Cover. Fitment and/or performance issues on aftermarket valve Covers are not the fault of the product but poor valve cover quality!**
 
**The Middle Prong of VU Cap has now been upgraded from AL6061 to ASTM A36 Steel that has also been Nickel Plated. For reference, ASTM A36 Steel is stronger than SS304 so it will be MUCH stronger than AL6061 and less likely to snap due to install error.**

Introducing the first of its kind, the N55/S55 Check Valved PCV Breather Cap, aka, the PCV Breather VU (Version Ultimate)!
 
This new breather cap will be a game changer in more ways than one! Similar to our B58 Gen1 VU Breather Cap, our N55/S55 PCV Breather VU during idle will still allow vacuum in the crankcase but under boost it's a different story. Once boost tries to get past the check valve, it will force the valve shut which will prevent any boost from entering the crankcase. In layman’s terms, stock PCV during idle with vacuum in the crankcase but under boost the PCV will be deleted! Best of both worlds! This will also mean little to no smell! This Breather Cap is also fully reversible if installed properly!
 
With this setup there are special requirements. With vacuum in the crankcase, you cannot just run a regular open style banjo as this will create a vacuum leak. This is why we designed a special check valve/PCV AN10 Banjo that will stay closed during idle to prevent a boost leak but open under boost to ensure the excess crankcase pressure is able to VTA! Three custom designs working in tandem with each other to create the ultimate solution to PCV issues! Sounds simple enough once explained but it's anything but, otherwise others would have already thought of it!
 
This kit will come with the ability to either vent through 1 port (other port will be capped) or vent through 2 ports. As mention, the AN10 banjo supplied for each port will have a check valve/PCV function that will stay closed during idle (vacuum in the crankcase) and opened under boost to expel excess crankcase pressure. Best of both worlds!
 
A OCC Combo will also be available but as of now, the OCC Combo will only be available for N55 F Chassis (F2X & F3X Models ONLY). For all other N55/S55 Vehicles, it will only be available as a VTA "Hose Only" kit. OCC Brace is NOT compatible with Strut Tower Braces!
 
VU Breather Cap is ONLY COMPATIBLE w/ motors w/ a functioning PCV! If Headports have been plugged, this Breather cap will not function as intended because there will no longer be any vacuum in the crankcase.
 
Pricing is higher than my other PCV Breather Caps but for good reason because this just does more! This cap is a much more complicated design with smaller, more precise parts and of course the required addition of my Ross Racing custom AN10 PCV Banjo fitting. It's ultimately 3 products in 1!
