You know, I really wanted to like these guys - I am a motorsport enthusiast and I want to believe they are too. But their terrible service has turned me off completely. Seems they could not process a simple credit card transaction for five days?? Adam promised to call me back with details of my transaction - never did. Terrible service. Bad way to run a business. I ended up just canceling my order and I will buy the AMG airbox from someone else. Bad way to run a business. I will not be shopping here again. Based on the other one-star reviews posted here, I am not surprised with my dissatisfaction. Do yourself a favor and avoid this business.
