on catalogs they sell **** under d16's, d18's blah blah blah...do d16 items fit on d15's??? like ignition wires, cam gears, pulleys, rods, gaskets, ...well u get the picture...

 

i think it totally depends on the product because the engines are different. for example i saw some ngk wire a while back and they were different 1 for the vtec model and 1 for the d15, on the other hand i have heard the dc 4-2-1 one piece header will bolt up to the d15 nad d16. i guess it just depends on the product
