Born in Warsaw, Kowalczyk played his youth football with local Olimpia and Polonez, joining city giants Legia Warsaw in 1990 at the age of 18. Almost from the very beginning, he was an automatic first-choice; in his weakest season, his first, he only appeared in 11 Ekstraklasa games, but was crucial in helping oust U.C. Sampdoria in the quarter-finals of the UEFA Cup Winners' Cup by scoring twice in Genoa for the 2–2 draw and qualification for the semifinals 3–2 on aggregate.
After having started the 1994–95 campaign with Legia (five matches, three goals, another league title), Kowalczyk moved abroad and signed with La Liga side Real Betis, but was never able to reproduce his previous form. He finished his five-year spell in Spain with UD Las Palmas in the second division, where he also appeared sparingly.
After almost one year out of football, Kowalczyk returned to his country and his main club, Legia. In late 2001 he changed countries again, joining Cyprus' Anorthosis Famagusta FC and netting a career-best 24 goals; after a nearly non-existent second season he finished his professional career in the same country, with APOEL FC, retiring at 32 – afterwards, he would play in amateur football until 2006, with AZS Absolwent UW Warszawa.
His biggest international highlight was helping the Olympic squad win silver at the 1992 Summer Olympics in Barcelona: he did not score at all in the group stage, but eventually ranked third in the charts at four, three behind compatriot Andrzej Juskowiak.
