Stock intake tube 90mm lightning maf

[boost88]

I've got a 90mm maf I'm wanting to stick in my stock tube obviously it's a tight fit. Anyone have a suggestion on how i can expand the stock tube? I know heat but I need to expand it evenly. I know I can buy an intake but I prefer not to right now

Tube is rubber, heat it up. Insert MAF. Tube will take the shape of the housing once its cooled.
