yeah iam confused too i have heard alot of ppl takeing these out which ones do i leave and which ones i take out please help me
From what I've gathered, the VTCS is what you remove and P&P, the VICS are what you're suppose to keep or else you loose a lot of low end power.
As far as I know, when the car is off, both systems are closed because when the mani is off the car, both are closed.
Well, you can open and close VTCS using the little lever on the side manually (when it's off the car), so the fact that this guy has it open is not indicative of anything.so this guy(the OP) rigged his VICs to stay open??? See below pic

The actuators will return to a default position with the intake manifold installed on the car or off. You can open and close both the VICS and VTS with the intake manifold still on the car.
The VICS remain in the open position with the actuator installed. I installed a check valve on the VICS actuator and gave it vacuum to move the rod to the fullest extent and went for a drive. The car had no power when I did that as it was gasping for air. I then removed the check valve which returned the actuator to the default position and the car screamed in comparison.
Now when I did this same method with the VTS, I couldn’t tell any difference between open or closed. So I am curious what the VTS does now.
Oh, that makes sense.
I believe VTCS does something to assist the combustion in some way on a cold start, and that's it. I believe it helps heat the cats (by swirling the air just right) or some nonsense like that. And that is all.
Some bs with car running cold that isn't important. lol. Thats why they get removed and P&P!
IYour thinking of the VICS
