Aftermarket IM worthwhile?

Curious about aftermarket IM’s… I currently just have a B17 with only I/H/E. Is there a point in getting say, an AEBS IM with my current setup? Or is it only benificial if I upgraded the valvetrain?

Also, would I need a larger TB if the IM is changed? Reading up on the AEBS, it says it has a 65mm intake… would I need a matching TB? 'cause I worry that the stock TB is nearly 10mm smaller it’s not going to make any difference whether or not I change the IM.

Anyhow, lemme know what you guys think. Still new to all this.

New cams / valvetrain first. Then breathe more.
