Reliable fuel delivery also contributes to smoother throttle response and better overall engine health.

How to Choose the Right Fuel System Parts for Your 2004-2005 WRX

Selecting the right fuel system upgrades depends on your build goals and current setup. For mild performance improvements, OEM replacement parts or slightly higher-flow injectors may suffice.

Always match components to your engine’s fuel requirements and consult tuning professionals to optimize performance safely.
