15- 21 Subaru WRX FA20 (5 pin TGV) Flex Fuel E85 REPAIR KIT (Harness and Module Only)

amazing.

I bought a used Cobb flex fuel kit but kept throwing the Cobb1 code. Well this fixed it and is amazing. Saving up to buy a second one to have as backup. Thanks a bunch Penguin Tech!!

Great product

Bought this as a replacement for my Cobb flex fuel system when my original module went bad and started throwing the Cobb1 code. Perfect plug and play, easy install, no problems, car is happy again and so am I.

1 month review- Worked as intended

Super easy install, remove Cobb harness and replace with new one. Fixed my Cobb1 code. Seems to be similar quality harness as Cobb. So far I’m very pleased with my purchase!
