Yes, those are early CBR900RR parts he used, as I recall. They are a direct swap; the later CBR900RR used coil on plug which the 919's electrical system is not directly compatible with as the ECU has no idea how to run it.
You will need 1999 or newer CBR900RR parts. Fortunately, the 900RR's caps/boots and wires are available separately. Using the 1999 CBR900RR for a base nets this part number: Cap, 30700-KY2-701, four required, $28.25 MSRP.
CBR900RR wires will electrically and physically work with the 919's coils (as well they should - the 919 and 900RR have the same coils) but the 919 has one coil mounted parallel to the frame and one mounted perpendicular where the 900RR has both coils perpendicular so the length is different.
One issue is that the 900RR parts actually cost significantly more than the 919 parts. Prices below are slightly discounted from MSRP and are courtesy of one of my local dealers.
Personally, I'd get new 919 parts and use a $7 can of this to change them from red to black.
That said... why are you replacing your caps and wires with just 24K on the clock? Honda wires usually last decades and 100K if not more.
