Horrible customer service! Purchased performance 70 mm throttle body for my Volkswagen MKV GTI.

Happy long time customer !!! I like this this company because they still do in house r&d. That’s big to me. I dont just buy parts. I research and purchase parts that actually are proven to work on my car.

Awful customer service and sent me a faulty part. Ordered a throttle body for my civic months ago and it was faulty. Sent it back to get my money back and fixed my civic with a new throttle body the day I sent it back. They said to get my money back the engineers have to conclude it was faulty. Tell me why I never got a phone call back and I just received it back in the mail after I had called them SIX TIMES NOT TO. I am seriously extremely frustrated with you guys and I will never be ordering from here again.
