Genuine product. ● Price reduction not possible. ● Not for individual sale. ● We cannot address issues after installation. Although there is one in the photo, this is a set of 6. These are ignition coils from a 2008 SLK350, a running vehicle. They were functioning correctly when installed and were removed when the car was scrapped the other day. Coils are a weak point for Mercedes-Benz, so these are good for spares or repair. Others are selling them for around 10,000 yen each, but since this is an expensive part, why not take this opportunity? I am not an expert, so I cannot answer questions like "Will this fit ●●?". Please research that yourself. Non-smoking, no pets. Thank you. #MercedesBenz #IgnitionCoil #r171 #slk
