No adapter needed mate. You may need something for the gaiter though as there is nowhere for it to clip in to on the Type S gear knob.
Any gearknob with a M10x1.5 thread will fit the Accord.
Mazda Knobs should fit as well. You could get one of these. http://www.ebay.co.uk/itm/250872926029?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
