Since the Cherries were defeated 2-0 at the Emirates Stadium, Howe's side have only lost one of the seven following games.
Despite that good run of form, the manager is wary of Arsenal and also setting points targets ahead of the run-in.
"Every weekend is pivotal," Howe said.
"Sunday represents a really good game for our football club, we're competitive and try to win.
"We're conscious of people setting 40 points but we haven't set any targets. We're working towards goals, but it's very dangerous to set 40 points as it could be more this year.
"I'd say we're more confident now than the last time we played against Arsenal, the run we've had and the importance of the fixtures we've been able to win has given us a renewed belief to compete against the very best sides."
Arsenal have won two of their six league fixtures in 2016 so far, seeing the club sit in fourth place in the Premier League table.
But the manager believes the Gunners will provide a stern test and praised Arsene Wenger for his Barclays Premier League tenure.
"They have a squad that when fully fit, is second to none," Howe continued.
"Their objectives are totally different to ours, we need to be at our very highest level against one of the best teams in the country.
"To continue to produce teams with the scrutiny of being one of the biggest clubs in the country is remarkable.
"I managed to talk football with him after the game he’s a very nice man and you can learn a lot from him."
