Customer Reviews
Been dealing with the COBB1 code for years and finally discovered this replacement harness. Quick install and my car finally rips
After finding out my Cobb flex fuel harness/ module had failed, I learned that Cobb had also left me with no replacement after they went “green”. I looked for alternatives and Penguin Tech Racing answered the call and all the questions I had. Thanks!
I had a bad Cobb kit and a bad ECU. I had to replace both, reflash and this got me back up and running after I months of trying to figure out what was wrong with my car. I had no fuel pump prime on key on, no check engine light, and no ability to pull codes. Car just died one day. This was part of solving the issues and I am back up and running!
Was recommended to get this brand, didn’t disappoint. At first I was having issues with reading my sensor but after uninstalling my tune and back on it worked fine. I’m running a Cobb v3 on my 99 Impreza. Please note that Cobb no longer supports this system so ask as many questions possible to your tuner first before buying it.
Thank you for your help and the part to replace my broken part.
