One of the most important upgrades for the Porsche 996 Turbo is to replace the factory Bosch diverter valves. The factory valves are prone to leaking pressure under increased boost when the car has an upgraded ECU flash. As well, the factory Bosch valves will taper boost off with the diaphragm design even at stock boost levels. To help keep the boost pressure constant all the way to redline, upgrading the stock diverter valves to the Agency Power Racing Diverter Valve Kit will improve your cars overall performance.

These valves are CNC machined 6061 aluminum which have been precision engineered to fit with the stock or aftermarket F-Hose and intake return hoses. The internal construction of the valve uses a machined piston with proper o-rings to ensure a smooth motion that is air tight to prevent any boost leaks. The spring has been engineered to hold moderate to aggressive boost increases on the 996TT vehicles. The valves feature a 90 degree removable swivel connection for easy fitting with the factory vacuum hose. If needed, the top of the valve unscrews allowing you to re-greased and service the valve. Valves are available in a polished finish and feature the Agency Power text and logo laser engraved on the top. As tested, these valves are a great upgrade for stock K16 or K24 cars and have even been used in our 700HP turbo kits. Valves are sold as a pair for the 2001-2005 Porsche 996 Turbo.

Dan,

Can you still offer the same deal ?

Ciao,

JE

 

Sent you an email. I will give you 50% off on the hose for being a return customer.

 

curious how the o-ring is seated into the piston or body of the dv's.

 

Why curious? The delrin o-ring is built on to the piston for a PERFECT leak free seal.

 

the reason why I am curious is depending on how the delrin is fastened to the body or piston the delrin can break down.

 

over 10000 of these have been made and sold since 2001 by manufacturer. No issues here and I guarantee them.

 

Are these made by Bailey? If so lifetime guarantee?

 

These are not made by Baileys. I offer a guarantee on all my Agency Power parts to my Porsche customers.

 

I was confused as your ad here claims as these "new" and then you claim 10000 have been sold.

I thought these may be Baileys as they look virtually the same.

 

This is a new product to www.agency-power.com. We worked with the original manufacturer on a slight exterior design change. They have made these aftermarket valves for many other major tuners. I appeciate your questions and interest.

 

Dan,

You also sell the APR1; how do they compare? The description on the AP describes disadvantages with the piston design.

 

dan, I just noticed the piston are notched. is there a reason for that? seems like the flat piston would be more efficient.

 

Danoyl what is the APR1 - send me links.

Oak - show me these pictures you saw...
