"I've been here two or three times but I always like coming back to play in England," Kumar said.
"It would mean a lot to get to go back to Lord's for the final of the World Cup.
"I have very good memories there, so if we reach the final it will be a very big moment for not just me but for the whole team."
India overwhelmed Bangladesh in their final warm-up match.
Lokesh Rahul and Mahendra Singh Dhoni smashed centuries as India posted a mammoth total of 359, sending out a warning to their rivals ahead of their tournament opener against South Africa on Wednesday.
"We got everything we wanted out of the match; when it comes to batting, bowling and fielding," added Kumar, who conceded only 19 runs in his five overs.
"Chasing 350 down is a very big task. There’s always extra belief when you go to bowl. You have the liberty to try few things."
