I sent an email back in June to King Motorsports (http://www.kingmotorsports.com) inquiring about Mugen products for our TSX. Here is what they had to say:

"Thank you for your email. We will have a complete Mugen performance product
line for the TSX shortly. Keep an eye on the news section of our website for
upcoming information and pictures.

Please let us know if you need further assistance."
