Re: Location of IAT Sensor

Welcome to AF!

Don't cut your wiring up installing one of those, they do nothing. Return the thing if you can, otherwise throw it on a shelf and forget about it. All they can do is make the engine run rich, so most people think "less MPG... must have more HP". Not true. You may possibly get a very small increase initially (but not even enough to feel it), but will lose it once the PCM learns what's going on, which is a matter of minutes of driving. The only lasting effect it will have is make you waste gas and plug up the cat. If you want more HP out of it, you need to get something that actually reprograms the PCM.
