looks like you have a ton of room. i use the black sewer rubber elbows that depot/lowes carries, 9$ with two clamps between TB and MAF, then another 90 or coupling to air filter (vans have round filters)
ls is 1.5 on bottom and 1.25 on top. Dayco flex hoses from summit (9-15$ each) are now cloth wrapped and look super awesome in an old truck install.
