Ok, so the weather is starting to get colder, so I've started to get the Cherokee all buttoned up to keep it warm over the winter. I decided to try something new this year and install what I call the "Partial" warm air intake. The reason I'm calling it a partial warm air intake is because I didn't want to cut any holes in my air box to do it. So I found a smaller 1-1/2" aluminum flex hose that would reach to the exhaust manifolds from the opening in the air box. My guess is this hose is about 1/3 the size of the opening on the air box. So far I have noticed the Intake air temps up about 10-20F from a cold start. Then after sitting for about an hour or so it pulls a good 100F out of the warm spot by the exhaust making re-warming the engine faster.
