The Tigers face Manchester City at the Etihad Stadium on Saturday, another testing away trip following their season opener at Chelsea.
Hull lost that match 2-0 but responded by defeating Norwich with 10 men for their first top-flight win since promotion to the top flight.
Manuel Pellegrini's title hopefuls will be expected to steamroller their opponents - partially in response to a shock defeat at Cardiff last weekend - but Aluko does not accept that is a formality.
Indeed, the former Rangers forward feels any team would be wrong to underestimate Hull this season.
"If they do, then they won't do it for long," said Aluko.
"In this league everybody gets watched, scrutinised and the managers do their homework.
"We always try to play football, teams will eventually see that. A lot of people said Hull will definitely go back down, like we'll be whipping boys, but I think people will be surprised.
"There aren't many deficiencies in that City squad but I'm sure the manager has a game plan for us to work on. We can't follow Cardiff's plans so to speak, we have different players, so we have to have our own game plan.
"We won't be starstruck at all. If you go there starstruck you'll definitely lose.
"They won't want to lose to two newly promoted teams but the Cardiff result gives us confidence it can be done."
Bruce echoed Aluko's sentiments, reiterating that Hull would need to play an active role in the game, rather than just park 10 men behind the ball.
He also took some succour from Cardiff's efforts, but realises a City "backlash" to their 3-2 defeat is equally possible.
"We are going to have to play well because we are playing one of the big, big teams in Europe," said Bruce.
"First and foremost you have to defend very, very well but the big thing for us is to take part in the game and pose a few problems if we can.
"All credit to Cardiff, they've shown there is light at the end of the tunnel for all of us.
"Manchester City didn't play too badly on the day, they were still very impressive.
"But we expect a backlash because that's what makes a really good player. They'll be desperately disappointed with how they lost that game."
