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… Read More

Agency Power has developed one of the best sounding and performing exhaust systems for the 2008 and up Subaru WRX Sedan. The new exhaust features an all T304 stainless steel piping in 2.5inch diameter from the catback. The piping is all hand polished featuring robotic TIG welding. The midpipe includes a resonator to assist in keeping that traditional boxxer engine sound with an exotic race tone touch that does not drone in the cabin. The ½ inch thick flanges offer a secure fit along with the factory placement exhaust hangers. The catback exhaust uses a high flow Y-Pipe to efficiently… Read More

One vehicle that Agency Power has had their eyes on for some time is the Smart car.  This compact econo-box is very popular and one that even the penny pinchers want to mod out.  Hey… Better air flow and exhaust flow make for a more efficient car and better fuel economy!  Agency Power cold air intake and exhaust system coming soon for the Smart Car!

One of our customers sent us these photos of the Agency Power Silicone Boost Hose Kit and F-Hose kit installed on his Porsche 996TT X50.  The customer installed these on the ground as he did not have access to the lift.  Took him about 2 hours. 

The boost hose kit is designed to keep the boost pressure consistant and will not drop like the factory rubber boost hoses that expand.  The F-Hose kit is a great maintenance part to change out when upgrading the factory diverter valves.

One of our dealers recently installed this Porsche 997 Exhaust system on a 2006 997 C4S.  The exhaust uses the factory tips and fits to the factory cats.  Each muffler is polished to a mirror finish and is all stainless steel and TIG welded.  Check out the 997 Exhaust Product Page Here.

All wheel drive cars are one of the best handling vehicles on and off the track. However it is normal for these cars to still have some under steer and not have a balanced chassis when entering and exiting corners. To improve upon the suspension system, Agency Power has developed these adjustable sway bars for the 2008+ GH and GE chassis Subaru WRX and STI. The sway bars are all made in the USA and feature new urethane bushings and brackets for the installation. The sway bars work with the OEM sway bar links or our Agency Power aftermarket… Read More

To improve the look and handling of the Subaru WRX STI, Agency Power has developed these performance racing springs. These lowering springs are designed to work with the factory struts on the 2008 and up GH and GE chassis of the Subaru WRX and STI. Agency Power has worked to get a spring rate that gives the car an amazing ride quality on the street, yet able to push limits on the track. The springs lower the car approximately 1.25 inches in the front and 0.75 inches in the rear for a good clean stance. The springs are finished in… Read More
