No. Simply an observation. And without the temps being equal, too many variables to give a cunclusion. For one thing, If the OP pulled his truck into the test bay, after it was sitting for any length of time, Then ran the test, and stopped it, the engine is going to continue to get a little hotter than it was when he shut it off.....Much like a Turkey pulled from an oven tends to cook a little bit more, even though the heat source was taken away. Anyway.....Then the "Cold air intake" is installed, engine fired up, and tested. Being as its now at a hotter temp, it should be running "Cleaner", as the optimal emissions is reached at opperating temp. Now.....If the engine temp was monitored, and both tests were performed at 185*, with the same load on the engine (from a rolling dyno, much like an emission place uses), some accuracy can be had, and the title of this thread would prove more relevant.
