I tried searching all over for my answer, but cant find exactly what I want so...

I am wondering, is the throttle body bypass valve required for the plenum spacer install or is this just something that helps the air coming into the plenum be/stay cooler and totally optional?

I live in NE Ohio, so obviously it gets cold here and the reason I am wondering is because i dont know if I want to have to worry about flipping the valve.. just last week 2 nights were at freezing or slightly below but the days were in the high 50's/low 60's...

 

It is necessary. When temps get to 55 or lower and you do not turn the valve the throttle body could freeze.

 

no, it's NOT necessary... just don't instal it.

 

The Coolant Control Valve is not necessary but it will allow your plenum assembly to run cooler.

If you have it, it will be helpfull to have it installed during the warm weather period. If/when it gets really cold outide just switch the valve to the ON position.

Being switched ON position will keep your throttle body from freezing in cold weather.
In the warm weather, the CCV switch to the OFF position will allow your plenum assembly to run a lot cooler.

Its nice to have it installed but it is not a requirement.

 

Ok.. Cool. Thanks for the clarification.. So I could install it and then as long as its ON, everything will be fine no matter what the temps. If I think of shutting it off during warmer temps, then incoming air will be cooler, thus more HP gain...? Ok...that makes sense..

 

Exactly.

 

i installed it on my car

i'll only have to turn the valve on for like 2 months a year
