Tom Ingram secured his third season win at Round 21 of the British Touring Car Championship, at Croft Circuit.
Tom Chilton was on pole ahead of the reverse grid alongside Dan Cammish.
At the start, Chilton pulled away strongly as Tom Ingram charged from third to first in four corners.
Stephen Jelley had a half-spin, causing the field to bunch up and Turkington gathered damage as a result. He later exited the pits on lap 7.
The fight for third was on with Matt Neal closing on Cammish.
After being squeezed onto the grass at the Complex by Aiden Moffat, Bobby Thompson and his Audi S3 rolled a handful of times, thus deploying a brief safety car period. He walked away from the incident.
The field went back to green flag racing on the eighth lap, with the distance increased from 15 to 18 total laps.
Ingram sought to establish the confident gap he led before the safety car deployment, with Chilton in second defending off Cammish in their FK8 Civic Type Rs.
Matt Neal in fourth had a queue of three cars behind, with the previous race winner (Josh Cook) at the tail of the midfield fight.
By the tenth lap, Ash Sutton pursued his signature climb to get in 10th from his start in 20th.
In the next few laps, Sutton made it into seventh and had gained 13 positions with a lack of success ballast.
By lap 15, Cammish eventually made it past Chilton for second place and Sutton had engaged himself in a fight with Tom Oliphant.
A temporary fix into fifth was short-lived, but he still pressed on in sixth having gained a total of 14 places.
The gap at the lead narrowed as Ingram sought to defend his position from Cammish and his pursuit for a fourth victory this season.
The duo battled in a close fashion, but Ingram secured his third win of the season ahead of Cammish and pole-sitter Tom Chilton.
Neal narrowly took fourth just 0.019s ahead of Ash Sutton, who had gained a total of 15 positions to still lead the championship by seven points, but from Dan Cammish.
Tom Oliphant claimed sixth position in his BMW 330i M Sport, ahead of Jake Hill and Josh Cook.
Senna Proctor and Aiden Moffat rounded off the top-10 finishers.
Turkington lost his second place in the standings to Cammish and fell to third, but is amongst the now closer fight for the outright championship title.
He also managed to score the fastest lap of the race after his woes, beating his reigning record and claiming a point to finish.
Ingram sits fourth in the standings, rounding off a 29-point difference amongst the top four drivers.
