Plenum warmer

MD thing is the CCV (coolant control valve). Above 55, keep it closed, below leave it open. Warms the TB. Not sure if all this was said, didn't see it when I skimmed over.
 
ISO thermal or basic

so i guess since i live in PA where we have bitter colds and muggy summers it would be best if i go with the iso thermal? would i be hurting myself with the basic MD spacer? :confused.:
 
Here's some more great info on the plenum warmer that was posted in another thread a while ago...

bypass is good for performance but if an inspection station happened to catch the bypass that's enough for a car to fail inspection, especially in cali... doubtful most any inspector would even catch that though unless it's done in a way that it's obviously noticeable at a glance...

How does it affect emissions?

the faster the car comes up to enough operating temp the faster it can go into closed loop, so the faster the emissions will be tightly controlled with a feedback system... years ago a car would have to run for 4-5 minutes or more before it could achieve closed loop operation from a cold start, modern cars can go into closed loop operation in a fraction of this time, heating the tb helps along these lines...

just to add to the above, tb freezing up is not the main reason of the tb warmer at all, but, it may be a factor in some designs for some manufacturers in some cases, so I won't say that it has nothing to do with that at all, it may in some cases, but it still not the primary reason why just about all modern cars use the tb warmer. for the most part that's more of a myth that starts with assumptions & then is repeated over & over throughout the net & becomes taken as gospel.

if you check this link & scroll down to test #5 you'll see that the tb warmer is a major component in the emissions control systems, http://www.avitestprep.com/gallery/l1-advanced-engine-performance-specialist
