The world No 4 pair, who are younger than No 9-ranked Soon Huat-Shevon, won 21-17, 21-11 in just 38 minutes at Arena Fyn in Odense, Denmark.
This marks their fifth win over their compatriots in eight meetings so far.
The Malaysians will now face either China’s world No 1 pair Jiang Zhen Bang-Wei Ya Xin or Denmark’s Mathias Christensen-Alexandra Boje in the semi-finals.
For Soon Huat-Shevon, it was another disappointment, as they have yet to reach a final this year, having only made two semi-finals and nine quarter-finals in the season.
As quarter-finalists, they take home US$5,937.
