Flex Fuel

I got the kit shipped really fast. Excellent quality, easy instructions. No issues with product & in top of that I saved a bunch of money compared to the Cobb for fuel kit. Used on a 2020 STI.

Great kit

This kit is very well made. The lines, the bracket that hold the flex fuel sensor, and the wiring harness are all made very well. This kit is priced at a good price for what you get. Would highly recommend this kit. Worked on my 13 sti without any issues, instructions are very clear and easy to understand. Only down side is the fuel line disconnect tool doesn't work very well that is supplied in the kit. Besides that, I would recommend this flex fuel kit to anyone who needs a flex fuel kit for their wrx or sti.

Fits and works great

Works great, tuner said it was very easy and nice to tune with. I got the fuel pressure sensor as well with this kit. Everything worked and connected great.
