NEXGEN Stage 2 + Flex Fuel Power Package STI 2015-2018

Unlock the hidden potential of your STI by going flexfuel with a new an improved tune. With EPA restrictions becoming more fierce, COBB has put out an answer in the form of their Nexgen kits.

NexGen Power Packages re-establish the modification and upgrade paths for supported vehicles that have been impacted by the removal of Downpipes. These packages provide similar performance and excitement, while maintaining legal emissions standards.

Many of the parts in this kit work in tandem to get your vehicle to the best performance possible. Whether it's fixing your stumble at 2800 rpm with the Fuel Rail Kit or decrease turbulence in the intake tract with the Silicone Turbo Inlet V2.

The NexGen Flex Fuel Module, which is mounted to the passenger side strut tower, handles all of the data processing before sending ethanol content to the ECU to be used by an Accessport-delivered NexGen Flex Fuel calibration.

Tying everything together is a custom, easy to install, plug-and-play wiring harness. Utilizing OE quality wiring and connectors makes adding NexGen Flex Fuel on your supported Subaru both quick and reliable.

Please Note: NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY EMISSION CONTROLLED MOTOR VEHICLE

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.
