BOV Kompact Shortie Dual Port Mercedes A45 AMG

The BOV Kompact Shortie Dual Port Mercedes A45 AMG is a genuine Turbosmart blow off valve engineered to improve boost response, throttle lift control and reliability in high-performance turbo applications. This product is supplied with the technical notes: Bolt-On Upgrade for Factory Diverter Valve Adjustable Product - Various Springs Available Seperately. Spring Pre-Fitted based on OE Application (Engine Vacuum).

Despite the AMG four's high boost levels, these vehicles do not have a bypass valve fitted from the factory. This is likely because the plastic valves typically found in OEM setups would not be capable of handling the A45's 26PSI of boost without failing prematurely. As a result, the AMG 45 models suffer from a significant compressor surge. Compressor surge, combined with the A45's high boost pressures, equals a recipe for disaster for the bearings inside the turbocharger.

Enter Turbosmart's Kompact Shortie Blow-Off Valve for the A45, CLA45 and GLA45 AMG. This high-performance billet aluminium valve bolts straight onto the compressor cover of the AMG's turbocharger. With both Dual Port and Plumb Back variants available, owners can choose between the classic blow-off valve sound afforded by the Dual Port's 50-50 split between a recirculating and vent-to-atmosphere operation or the quieter OEM-like operation of the Plumb Back. Both variants dramatically reduce the compressor surge experienced by the A45 in standard form.

The Shortie's billet construction and high-performance piston design, which eliminates the need for an O-ring to seal the body of the blow-off valve against the piston due to excellent machining tolerances, means the valve has no problem coping with the boost pressures produced by the AMG's turbo, ensuring no leaks and extreme durability - even if you decide to turn the boost up.

The VR03 Kompact Shortie Kit for the A45, CLA45 and GLA45 AMG includes a Boost Reference Adapter that allows the blow-off valve to respond to engine vacuum instantly, providing greater control compared to electronically operated valves. This is possible by allowing the valve to access a manifold pressure reference in the AMG's otherwise closed system - all without any destructive methods, such as tapping into the intake manifold. The Boost Reference Adapter offers two pressure ports, allowing you to run a second manifold pressure-operated accessory, such as a boost gauge.

Fit great, good price, and fast shipping for a last minute NYE dinner
Let me start by saying that I had very low expectations, all I truly cared about was getting something “blingy” as fast as possible for a last minute New Years Eve dinner. I was impressed by the speed of arrival, price & floored by the quality. Now of course, this is NOT a tailored $300 jacket, but it was great for our evening. Did not shed any sequins, no problems with wrinkles, and didn’t have any weird smells. My husband said it was comfortable, and he plans to wear it again should the need arise.

Classy but stands out!
I bought this jacket for my teen son for homecoming and it was perfect! It was a great fit and the look was just as pictured. I have purchased several things from this seller for formal events and highly recommend them!

Not what I ordered!
Color: Silver, Size: XX-Large, Color: Silver, Size: XX-Large
I ordered this jacket for my boyfriend for New Years. Not only did it not fit according to the size chart (too small). It was nothing like what was pictured on the listing. The sequins were very light and cheaply sewn on. And the lining and button were WHITE! Not black as pictured. I have never had a problem with anything I ordered from Amazon until now. I returned it and was refunded. But, now have to find a different jacket. NOT HAPPY.
