would be a bit suspicious with this, a google search using a variety of CORP/CORP silicon/CORP hoses/CORP performance etc has only turned up a facebook page, made in 2011, with nil info. It has 13 likes and literally the ONLY info are the two pictures from Ebay, a brief blurb about how they make superior silicon for "everything", and "lixuansport.com". can't find any other evidence of their existence. Lixuansport.com is full of engrish, requiring their distributors to have "exalted professional morality". And under their mazda section, they don't stock anything for the MPS, other than some radiator hoses for the atenza. (unless they just never update their products page). Then again, if they are legit, cheap hoses. sweet as.
