The GREATEST online European parts… The GREATEST online European parts supplier on the planet. I have been a loyal ECS Tuning customer for over 8 years. I have been an automotive enthusiast/technician for over 37 years. I have dealt with BimmerWorld, Euro Tuning and FCP Euro and ECS Tuning is the only place that consistently exceeds my expectations in every department.

Worst company ever , DONT BUY ANYTHING Worst company ever Should be out of business Worst customer service in history Waited over 2 weeks to receive the wrong part Then another week or so trying to talk to somone in there customer service team (they dont answer the phones or email back) Its now been over a month and i have had to fix there mistake myself I dont EVER write reviews EVER unless im that satisfied with customer service for example ARM is above and beyond with there customer service and shipping speeds I went ahead and made this review to show how awefull they are Im that mad and dissatisfied that i wrote a review on every single option to leave a review on This is beyond a disgrace of a company

ECS is my go to for anything BMW ECS is my go to for anything BMW. The parts are generally reasonably priced, some great deals come around, and you can get some really quality products. Their staff is ALWAYS helpful with questions and guidance. Never been steered wrong. I get parts for my 1985 535i, 2007 Z4MC, 2007 X3 3.0si, and the 2014 X5 xDrive35i - so their continued support of old and new cars is really important to me.

Hard to find OEM+ oil for my b6 Audi S4… Hard to find OEM+ oil for my b6 Audi S4 avant, thank you.

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.
