I would think it is better because there is less heat unlike being in the throttle body but I'm not 100% sure. Hopefully someone can chime in. It could be and do the same thing also.

What do you mean "is it better?". They are two different things completely. The TB bypass valve makes the throttle body cooler. The Iso Copper Plenum spacer keeps the engine heat from conducting from the lower to upper plenum. I think both have neglible effects because the TB is small, and in the case of the Iso - that heat is still somewhere (lower plenum).

So many question about keeping your plenum cool? If you live in the south/west United States you need the TB bypass/copper gasket to keep your plenum cooler during hot weather! Our VQ motors love cool which is evident by how easily SLICK lights up my new Michelin's this time of year. Spacer corrects Nissan's design error, TB bypass ISO keeps everything cooler....simple!

I've been working on these cars more specifically the engines for a while and what the throttle body coolant lines do is they warm up the throttle body, the benefits of this are that in colder weather the engine won't have to use so much more fuel because with the throttle body warned up it increases the temperature of the air intake charge enough that it keeps the engine from running to cold and running rich or throwing a code for temperature to low. As everyone else said though these engines do like colder air, so get a valve installed so in warmer months you can turn the coolant flow off and then back on in colder months. People seem to to forget that colder air requires more fuel so the air/fuel ratio is correct. Hope this helps you. If you need anymore car advice feel free to add me on Facebook. Mark Auber
