The main cause of your mental and finacial strain stems from your inability to pop the hood and look at your turbos. Had you been able to shine a flashlight on the rear turbo, you would have seen the collapsed inlet. |

Can you please tell us who installed these inlets? It's pretty obvious that the coupler is installed in the incorrect orientation which is exactly why you're experiencing that crimp in the coupler.
The couplers for each turbo are NOT interchangeable and they are unidirectional. You'll experience this exact issue if they're installed in the incorrect orientation or if the incorrect coupler is used on each turbo. I apologize greatly for the inconvenience you've experienced but any installer worth their weight would NEVER have left that coupler kinked prior to giving you back the car. It's even more surprising that they did it twice. We have thousands of these in the wild successfully installed but the only difference between the successful installs and yours is the installer in question. Please note that we could have easily resolved this issue for you if we were contacted when you began having these issues. The problem wouldn't have taken long to diagnose after a picture or two were taken. Last edited by Tiago@VRSF; 04-10-2020 at 06:02 PM.. |

I do agree with you that this could have easily been resolved by having the client consult the manufacturer directly for support prior to assuming their installer was incapable of error. |

i just recently installed the 1.75" oem inlets from you guys and they are working fine.... BUT am concern as you mention the clamps are uni-drectional. how to tell which clamp which side and which end? went to your site to check if there was documentation but didnt find anything. also there wasn't any paper work in the box to state it either.. let me know if there are any indications on the clamps so i can double check the work car has only been on the road for less then 24hr since we completed the job. fyi i also have your race 7.5" intercooler and cones. maybe a public answer will help everyone easy their minds. thanks |
