NNBS Intake help.

I’m putting a nnbs Intake on a 04 Denali with the 4 bolts dbw throttle body. I plan to mod my stock rails and use the stock throttle body from the 04. Do I need an adapter for the throttle body and if so where do I get it?

Just get the new square metal style rails. I got a set off ebay super cheap. If you poke around there is a 4/3 bolt adapter sold in black AL and you can't even tell its there!

Buying those throttle body adapters make putting that intake on useless.

Why downgrade an upgrade by choking its inlet with a small opening?

OP search around for a larger 4 bolt DBW throttle body and make good use of the intake

I would look for a set of square rails also, you will save your self alot of headaches trying to mod your factory rails
