Conor Daly was fastest overall but it was Ed Jones again setting the non-tow pace on the final day before qualifying for the Indianapolis 500 begins.
Daly set a 38.8426s (231.704mph, 372.891km/h) on his 54th lap in the #25 Andretti Autosport Honda to usurp team-mate Marco Andretti (#98 Andretti Herta w/ Marco & Curb-Agajanian Honda), who clocked his best of 38.9862s (230.851mph, 371.519km/h) on his second lap of Day 4 of practice.
Second through ninth were covered by less than a tenth of a second with the top 12 all setting a lap at an average speed exceeding 230mph, as turbos were turned up to 1.4 bar in preparation for qualifying.
Rounding out the top five were 2017 race winner Takuma Sato (#30 Rahal Letterman Lanigan Honda), Spencer Pigot (#21 Ed Carpenter Racing Chevrolet), and Ryan Hunter-Reay (#38 Andretti Autosport Honda).
Will Power (#12 Team Penske Chevrolet) was 11th, Scott Dixon (#9 Chip Ganassi Racing Honda) was 16th, and James Davison (#33 DCR w/ Byrd-Hollinger-Belardi Honda) was 23rd.
Having missed the day prior as McLaren Racing built up a spare chassis, Fernando Alonso put the #66 Chevrolet into 24th position.
In terms of non-towed laps, Jones remained the pace-setter with a 230.106mph (370.320km/h) effort in the #63 Ed Carpenter Racing Chevrolet, just ahead of Ed Carpenter himself (#20 Chevrolet) at 229.879mph (369.954km/h).
Power was fourth fastest on non-tows, Dixon eighth, Davison 20th, and Alonso 30th.
Kyle Kaiser produced the day's major incident when he clouted the wall at Turn 3 in the #32 Juncos Racing Chevrolet, although the 22-year-old was thankfully uninjured.
“This is not what you want to be doing on the day before (#Indy500) qualifying.”
Kyle Kaiser is OK after this crash in practice, but the team faces a major setback as it tries to make the field of 33. Watch on @NBCSportsGold: https://t.co/PqVUeFoq4g#MustBeMay pic.twitter.com/esjN3F8z2V

Graham Rahal would later get away with a touch of the wall exiting Turn 1 in the #15 Rahal Letterman Lanigan Honda.
