Have an 89 258 Jeep with Dual Fuel (gas/propane)Propane, well where the mixer is with the air filter? There was a coolant hose right in front of my air filter. Big deal? No, but it is hot ambient air right in front of my filter, lol. Slapped this on and you can touch it now, that’s how much it went down. Now, I’m gonna do the rest of the vehicle. My Jeep is kinda hot rodded, but obviously not setting speed records, lol. But I’m out to make power with efficiency. Keep hot things warm, things that like to be cold cool. This is a great way to do it.
