i drive a 2000 ford crown victoria and it has 666,450 miles, yes actual miles w/ orig engine, trans etc and it still runs strong even prolly better than a car with 100 k miles lt;knock on woodgt; haha, well any ways i was thinking about adding a cold air intake to it, and was wondering if this improves the sound of the car and if it helps with gas mileage or worsens it and around how much this costs or if its even worth it and wheres best place to get it.
I'm not quite sure what you mean by cold air intake. Everybody who knows anything about performance understands that the colder the intake charge, the more oxygen gets into the combustion chamber (colddensemore O2 molecules per square inch). That's why an intercooler is the hot ticket when using a turbo or supercharger. And as far as I know that's the only way to get colder air into the intake. First you run the incoming air through a turbo or a supercharger which compresses the air which results in higher air temperature, then you route it to the intercooler which takes the hyper thermic air and knocks a few degrees off of it. When the air goes through the throttle body or carburetor butterfly valve, the release of this pressurized cooled air creates an instantaneous hyper-cooling just before the air enters the intake port/valve. Cost? I dunno, you'd probably pay a couple grand for the hardware and another grand to have it installed. But beware. When you start messing with perfection you often get unexpected results. The additional O2 is going to give you a helluva lot more pop. You'd be surprised what a little oxygen does for combustion! You may find that 666,450 mile old lower end of yours starting to knock on you. It's got an established wear pattern from doing what it's been doing, and now you're asking it to do something that imposes greater forces on all the parts that go up and down and round and round. By the way, you're my new hero. I've never heard of anybody ever getting 666,450 miles on a gasoline engine. That's way beyond anything I've ever heard of. I take meticulous care of my '66 Chevy and only have 250 miles on the current engine, which is more than I ever got on anything I've ever owned.
