The stock fuel rails and lines allow more fuel and pressure to be distributed to other cylinders while cyl #3 runs lean. When WRX owners begin upgrading the engine with high performance components, this problem gets even worse.
The Perrin fuel rail kit solves all fuel distribution problems. Perrin fuel rails direct fuel to both banks of cylinders and to the fuel pressure regulator.

Pros:
w/ the right a/f set up, more fuel means more power!
Cons:
fuel economy may suffer..
The Perrin fuel rails are specifically designed to retain correct fuel injector alignment. If the fuel injectors are not aligned correctly, the spray pattern will also be misaligned. The fuel will now be directed towards the cylinder port walls instead of into the air charge. Uneven distribution of the fuel into the cylinder and pour atomization will result. Under load poor performance and sporadic air fuel ratios may result.

Pros:
Peace of mind mod, stainless lines
Cons:
Difficult install
The Perrin rails are more of a peace of mind mod. There are many folks running 300+whp on the stock rails. I however did not want to take a chance when I went to my full Vishnu Stage 2 w/ VF30.
The install is kind of a pain. Mine was easier since I had removed the intake manifold, but that is an adventure by itself. The Perrin system comes completely assembled and bolts right in. The only word of caution is to check the injector holes for metal shavings from manufacturing. I ahd an oring rip and developed a major fuel leak that required a parking lot oring swap! Put a light film of oil on the oring before inserting the injector into the fuel rail.

Extra bit of security and they look good
