rejet with diferent filters?

[sparks400ex101]

i know this is dumb , and i figure the answer is no , but do you have to rejet when you switch filter? i run a sparks pipe with sparks filter, and i want to switch it back to my old K&N, and my dealer jeted it with my sparks filter which is foam , will it be ok to switch to k&n without rejetting?

I went from a K&N to a Uni and did not need to rejet.
