After another three slow laps it was green flags once again with Kristensen now tucked right under the bootlid of the leading Vectra. Jason however judged the start perfectly once again and was able to fend off the Honda's attentions into Riches. Kristensen had another look down Revett straight forcing Plato to cover his line although the Dane was now coming under pressure from Rydell and had to back off.
The first lap was completed without drama and by the end of it Plato had eked out a few car lengths over Kristensen who in turn had moved clear of Rydell. Reid, whose car was feeling slightly odd after suffering two assaults from other machines, was still managing to keep the pressure on Rydell while Neal was defending his fifth place with great determination from Tarquini.
As the race wore on Plato was able to stabilise the gap to Kristensen at just over a second. The Vauxhall was working exceptionally well in the cool conditions and from mid-distance Plato's only worries concerned the lapping of the Class B machinery. Thankfully everyone behaved themselves and Plato was left to reel off his first win at Snetterton.
Kristensen remained in reasonably close contention throughout and occasionally closed in on the Vectra whilst lapping traffic although he never got close enough to attempt a pass. The Danish driver was not bothered by the fading light as several others were thanks to his recent Le Mans experience and was quite happy to gain valuable points in his quest for a top five finish in the championship.
Rydell meanwhile found the burden of 40 kilos of success ballast too much for his Mondeo and he eventually dropped more than five seconds on Plato. In the latter stages of the 22 lap encounter, Rydell found his third place under increasing attack from Reid who closed to within half a second of his team-mate at the end.
Matt Neal finished fifth, ten seconds behind the winner to continue his good run of recent form. Tarquini had given the Independent Nissan driver a good run for his money for much of the race, relentlessly hassling the lanky Englishman for all he was worth until a late race problem forced him to drop back.
In Class B Alan Morrison had to overcome starting from the back of the grid after his Peugeot failed a post One Shot Showdown technical inspection, but still took the class win and seventh place overall.
Remarkably the Class B brigade behaved themselves impeccably and the only retirement was that of Robert Collard who lost a top three finish in the final six laps.
Behind Morrison, James Kaye followed the Peugeot passed the rest of the class to take second place after a good scrap with Barwell team-mate Mark Lemmer and Collard.
Despite his retirement, Menu kept his championship lead during the break between races thanks to Reid's exclusion from the Croft feature race. However the Swiss driver cannot afford another debacle like he suffered in the sprint race.
