To combat this issue, Perrin created a complete fuel rail kit. Each kit is specific to your Subaru WRX STI model and includes everything required for installation. Made from 6061 billet aluminum and anodized black for solid feel and finish. Each kit has multiple ports with -6 AN fittings. The reinforced hoses are durable and fully capable of supporting E85 as well.
Key Features:
- Kits are direct fit to each application.
- Some applications convert your factory side feed style injectors to top feed ones. Flows much more fuel than stock.
- Equal length design ensures no single injector gets starved, even on very high-output engines.
- Uses phenolic spacers to keep fuel rails from getting heat soaked.
- Some kits include the junction block as well.
- Uses large -6 AN adapters pre-installed for easy installation.
- Fuel lines are tough and support E85.
- Can handle up to 800 whp.
- No tuning required.
- Where noted, Flexguard covers are included to protect fuel lines against heat and abrasion under extreme conditions.
- All hardware needed to install is included.
- CNC machined from solid billet 6061 billet aluminum.
- Features a sleek black anodized finish.
Top Feed Fuel Rail Conversion Kit Notes: Modern top feed injectors are easier to tune, less expensive, and flow more fuel than the side feed alternatives. Perrin Top Feed Fuel Rail Conversion Kits are engineered as a system where the injector, rails, and mounting hardware all work together to integrate flawlessly into the OE manifold and mounting points!
