The BOV Kompact EM Plumb Back VR25 - 400 Z is a genuine Turbosmart performance part designed for reliable operation, precise fitment and proven results on street and track builds. This product is supplied with the technical notes: Bolt-On Upgrade for Factory Diverter Valve.
The multiple award-winning Kompact EM Series of upgraded Blow Off Valves is the world's first truly plug-and-play upgrade solution for your factory diverter valve. Unplug and unbolt your OEM valve, and install a Kompact EM valve in its place. No adaptors, hoses, or extra assembly are required.The Kompact EM Valve Series from Turbosmart takes motorsport-proven billet valve technology and adds an onboard, proprietary solenoid system and internal pressure control channels, resulting in a simple plug-and-play valve with full OE integration and control. There are no reference hoses, no separate solenoids, and no fiddly bits - Just bolt-on and plug in!
You can count on unmatched performance and reliability as a direct replacement for your factory diverter valve. The Kompact EM Valves overcome the common faults associated with plastic factory valves through our Boost-Balance Valve Design (the more boost you have, the better it seals), a positive seal O-ring on the piston's face, and billet construction. No matter your application, the Kompact EM Series will hold more boost and be more responsive in any environment.

That wasn’t too big or bulky looking on my bathroom wall.
It was a perfect fit for my bathroom, cabinet hanging over the toilet.

Easy to assemble and install
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
This cabinet meets our need for more bathrooms storage without interfering with the space in our smallish bathroom. The package arrived well packed in cardboard with foam inserts to protect the parts from damage in transit. I was able to easily follow the included directions with minimal fuss. In several cases, extra hardware piece were included, which I really appreciated. The quality of the construction was excellent. The only this that concerned me was the weight bearing capability of the included shelves. I added a few liquid or lotion filled bottles and noticed the shelves sagging, so I may have to cut my own shelves to better support. The cabinet looks great and is exactly as pictured in the listing after I assembled it. The ability to customize the shelves is also helpful. I looked at several cabinets for this purpose, some more expensive, some less, and I am happy with the money spent for this cabinet.

Great bathroom cabinet!
Color: White, Style: Wall Cabinet
My husband mounted this cabinet over our toilet and it’s the perfect addition! It looks great, matches the cabinets we already have and adds much needed storage! I plan on buying a second to put in my daughter’s/ the guest bathroom. The doors are magnetic and close securely, and the shelves are adjustable and feel sturdy. It was very easy to put together and feels very secure mounted on the wall

Mounting process could have been easier but still a beautiful cabinet
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Beautiful cabinet seems to be good quality I just keep admiring something so beautiful about the white. The extra hardware is thoughtful.
With some master skills I was able to get it mounted perfect. It was not a breeze but nonetheless I always find a way.
I found the best way to mount this was to hold it against the wall and follow the pre-drilled holes at the bottom to drill the holes into the wall that wasnt that hard
But for the top anchor/screws, the cabinet did not have pre-drilled holes and I was not about to guess !! So I used alien tape to tape the top wood bar to the unit as shown in pic then took the cabinet lined up the bottom holes while holding the cabinet up then I drilled holes through the unit with a small bit just to get the whole going then took it back down then followed the same holes with a bigger bit and it worked for me. It hung level.
It was crazy that the pre-holes were not 16” apart when they could have been. I added extra screws to be able to mount them to a stud I didn’t feel comfortable with it not being mounted to a stud. The screws I had were too long gonna have to get some shorter screws. But it’s up & looks so nice
DO NOT USE 11/32 bit. Don’t even use 5/16. I use 1/4 and kinda ran the drill in a circle to widen the whole and it was the perfect tight fit
All in all I do love the cabinet. Just feel the mounting process could have been instructed more conveniently
