Don't rely on ECS Tuning application guide Based upon website guidance, I ordered an auxiliary input wiring harness for my 2003 Mercedes C240. I received it, decided to do some online verification before opening the package. I learned this harness wasn't compatible with my car's wiring. After a lot of hassles I was authorized to return it. I paid shipping both ways for a part incorrect for my car, despite the website claim it would work.

Great Customer Service Had an issue with wrong rotors and ECS made it right without me even asking. Their selector showed rotors that did not mention vented or not. When I received them and took my mine apart mine were vented but 5he ones ordered were not. I called up and they said, don’t worry we will get the correct ones to and they did.

superb as always i have been using ECS for years and they always deliver quick and a very friendly staff. I have never had an issue with any orders and all the parts were as described.

Bought coated rotors that rusted in 6… Bought coated rotors that rusted in 6 months, In order to get a refund I need to purchase another set from them , I told them I would send them back and if they can return my money? Th Amanda there customer service manager, stated the only way is to repurchase again from them and they would issue a credit . There "HOME OF THE LIFETIME REPLACEMENT" IS A COMPLETE SCAM! I'M AFRAID IF I DID SEND THEM BACK I WOULD NEVER SEE MY MONEY OR CREDIT FROM WHAT I'VE BEEN READING ON ALL THESE SITES THEY'RE A FRAUD AND I NEED TO BE STOPPED!
