Do you guys think 3/8" vacuum tubing is big enough for the needs of the IAC?

Thanks!

I had no problems with 3/8" tubing on mine when I ran the aluminum 3L UIM... I tapped the bottom of the stock IAC for two 1/4" threaded to 3/8" barbed adapters and it idled nice and smooth all year round.

Okay then yes.

I'd think that without any you wouldn't want to drop a 5/8" tube down to a 3/8". I suppose it depends on everything from pcv size and air leakage at the throttlebody. I always sealed everything on my TB, including the small centerhole so I kept the stock sized IAC line.
