iaTUNING Fuel Pressure Regulator Kit
This kit is a directly plug and play solution for STi models (2008-2020) exhibiting a part-throttle stumble in the power band between 2000-3000 RPM. Each kit is comprised of the following:
High Pressure Fuel hose
900 psi burst fuel hose is designed specifically for fuel injected vehicles and is resist to gasoline, oil, diesel, e85, and other fuels. This hose meets SAE specification J30R9.
Subaru Fuel Pressure Regulator (FPR)
By using a high quality Subaru factory FPR we were able to take the guess work out with its simple operation. Preset at 43 PSI static pressure.
Plug and Play Hose Ends
Made from durable nylon/resin, the hose ends offer a clean, factory appearing, connection.
Constructed of stainless steel, these continuous band clamps offer a firm clamp load to every hose connection.
FPR Stay Bracket
Used to attach the FPR, these parts consist of: rubber insulated Stainless Steel band clamp with nylon locking nut and bolt.
FPR Vacuum Source Relocation Kit
Includes all necessary parts to relocate the vacuum hose, which further diminishes the lean spot / GR Stumble. Includes: 4mm vacuum hose, vacuum reducer tee, zip ties.
60 Day Product Warranty
Warranty specifically parts of the kit only. If deemed failed by iA-Performance (after following our tests), then a replacement part(s) will be sent out. Warranty does not cover external items to the kit, motor, turbo, etc.
Attention Non North American Customers
It has been brought to our attention that the North American and Non North American STi have different methods of attaching the fuel hoses to the fuel rails, yet both still use quick disconnects at the firewall side. Thankfully, we cater to both markets and make kits for either application. Please reference the product photos to decide which version you have, then properly select this Model Type from the drop down menu next to the Add to Cart button.
