BOV Kompact Plumb Back VR30 Suits Audi 4L V8 TFSI
The BOV Kompact Plumb Back VR30 Suits Audi 4L V8 TFSI 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.

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional.
When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use.
The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings.
The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use.
Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
