Question about CAI to Throttle Body/Intake Plenum

[98GTnSC]

im planning on buying a JLT CAI and the 78mm Throttle Intake from BBK. its a 78 mm intake plenum with a 78mm throttle body built into it. but i just read on the Latemodelrestoration.com description of the JLT CAI that the smooth taper reducer would fit up to a 75mm throttle body. could i make the CAI work with the Throttle body? just maybe stretch the reducer over the throttle body? thanks for any help. JLT CAI part number on LMR is JLT-9604BLK. BBK Throttle Intake is BBK-1780.

I have the JLT rai. Its a tight squeeze but it fits fine.

i had to buy a 4" silicone coupler for my MAC CAI to fit mine. but it worked out good as i was changing the couple color to red anyways.

the clamps have since been changed out for T-bolts BTW.

so if i have to i can just buy a 4 inch coupler or something along those lines like sik93coupe did and it'll work?

running the bbk 78mm with an American Muscle CAI. it is a little rough to get on but I made mine work.

how big around is the AM CAI? the JLY will be 4". im sure ima end up having to get a bigger coupler

The coupler JLT includes is a reducer, it will work fine right out of the box

ok. well it said that it would fir throttle bodies up to 75mm and 78mm is how big the new 1 will be. but i'm sure it'll give me 3 more mm....
