Custom/Gutted intake.

[Bob K]

Hello-

Is there any benefit to increasing the airflow to the Northstar, ether by gutting the stock intake or installing a custom one? Thank you!

In the tests I did with my 1996 STS there was no improvement by adding a cone filter or modified intake that I could find. Greg Garcia did some back to back dyno tests with a Aurora 4L NS that showed some improvement, on the other hand.
