They list 92-94 injectors- and 1% flow matched even Those years injectors had higher flow rates- in 96-99 they were the corporate flow rate which was like 23.2 lbs/hr at 49psi. Those upgrade injectors are significantly lighter than the original style pintle injectors and its your decision on pintle 1 hole vs 4 hole sinjectors. Controversial topic. I like the lighter 4 hole injectors- running 2 sets- one in a 2001 5.9 and one set in 99 5.9.
