Alonso has led the drivers' championship since winning the European Grand Prix at Valencia, but he is in danger of becoming the hunter rather than the hunted with Sebastian Vettel lying just four points behind the Spaniard.
The Korea International Circuit proved to be a strong track for Red Bull in 2011 as Vettel took his 10th victory of his remarkable march to a second world title.
A repeat of that result this weekend would see the German leapfrog his rival, and with a lack of qualifying pace undermining Ferrari's race efforts, Alonso appears to be facing an uphill battle.
But the 31-year-old is backing the Maranello squad to help him take the title battle all the way to the final race in Brazil.
"I am sure we can be in the fight right down to the wire," said Alonso.
"The people who are working on the car are the same who have done the job so far and there's no reason to think they can't do a good job again now.
