The world number three followed up back-to-back third placed finishes at Omega European Masters and KLM Open with a runner-up finish at the Alfred Dunhill Links Championship last week.
But after finishing third behind Bae Sang-moon at the 2009 Kolon Korea Open, McIlroy is hoping his familiarity over the tight Woo Jeong Hills Country Club layout will be the key to edging out the likes of 2009 PGA Championship winner YE Yang, American Rickie Fowler and OneAsia Order of Merit leader Andre Stolz to claim a fourth career title at the KRW1,000,000,000 event.
"I haven't had another win since winning the US Open, but I have been knocking on the door," said the 22-year-old.
"I was very pleased with how I played last week, especially after the shaky start I had on the first day being three over through 11 holes. So finishing 20 under was a pretty good effort, although I felt like I could have got a bit more in the final round, especially on the last seven holes and got a couple of birdies out of them.
"But I gave it a pretty good run and second was a decent finish and I am hoping to go one better this week.
"I really enjoyed myself two years ago when I came to Korea and I played well and could have won, but I finished third. Because of that I took the opportunity to come back and try and win an event that I have come close at before."
While McIlroy is chasing to add another title to his trophy cabinet, 2010 US PGA Tour Rookie of the Year Fowler is looking to claim the elusive first win of his career.
The world number 36 has posted four top-10 finishes this year, including a fifth place at The Open and runner-up finish at the WGC-Bridgestone Invitational.
"It is a good course and I have been playing well and I am looking forward to a good week," said the 22-year-old.
"I need to start winning. I feel like once I get my first win out of the way things will be a lot easier and more wins will come. I feel like I need to break down the barrier of the first win and I feel like I'm getting close.
"I am comfortable when I am in contention; I just need to get there more often.
"I didn't have as many high finishes this year as my first year on the PGA Tour, but I played a lot more consistently and made a lot more cuts, so hopefully we can get the best of both worlds next year."
New Zealand's Danny Lee, meanwhile, is hoping to follow up his play-off victory at last week's WNB Golf Classic on the Nationwide Tour, which secured the 21-year-old a US PGA Tour card for next year.
Korea-born Lee, who won the 2009 Johnnie Walker Classic as an amateur, finished seventh at last year's Kolon Korea Open and will again be in the spotlight over the opening two rounds this year as he tees off alongside McIlroy and Yang.
"I had a really good week last week and I am going to play on the PGA Tour next year," said the 2008 US Amateur champion.
"Hopefully having the PGA Tour card will make me more relaxed. I think I have done enough this year, but I finished seventh last year at the Korea Open so hopefully I can do better this year."
