power modification
i found a site on ebay selling a resistor pkg to increase power. It installs in the air intake temp wiring and fakes the engine computer into thinking the intake air is always a low temp, like 56 degrees, They say this helps milage and power. I can believe the power part, lower air temp means more oxygen per cubic ft. of air. but, that means more fuel. power is up, but not milage. Any others have a comment or idea?
I did further research on the e bay site and found the resister value, you can ( I did) buy the resister 5 for .99 at radio shack. haven,t figured out how to install w/0 having to cut into the harness at the air intake sensor right on the intake tube.
really looking for some input.. thanks

I don't recommend that kind of hack. Which would void your warranty. I there are a lot of legitiment ways to improve power and economy. For starters I would recommend getting your vehicle on a dyno to do a base line for comparison. Then add an air intake kit for starters. This would passively reduce restrictions which in turn improve throttle response, higher engine efficiency, and power... while not voiding any warranty. There's lot to be upgraded and never will you ever need to install resistor to your intake temp sensors.

I purchased a similar product from SLR motor sports That also ties into the cold air intake wiring.It promised an increase of 50 horse power and 3 to 6 mpg.The install directions were very generic and I spent several hours on the phone with dealers trying to find out which wire was which on the air intake sensor plug .Finally after 5 dealerships I got a mechanic to tell me the right wire to tie in to.What a waste of time and money.I saw no noticeable improvements in gas mileage or horse power.I would try an air intake kit or go with a reputable re programmer like super chip.Don't make the mistake I did and hack into your wiring because the price was right.

I agree with everyone else, the volumetric difference between the cooler temp reading, and a correct ambient air temperature reading, only serves to increase the injector pulsewidth, to compensate for the amount of extra oxygen coming in... Plain elglish: more oxygen requires more fuel = less mpg, and the actual horsepower gain is miniscule, 2-5 hp, at best! Maybe if it were a 25.6 liter engine, you might see 50 horsepower!
People will say anything, to sell anything, these days...
Every car I've ever owned, I've always looked for ways to add a few horsepower... Never has it been cheap, or easy...
Now, if you want to add some real horses, get an actual cold air intake system, from a reputable company, like K&N, Volant, etc., then get some exhaust work done.
I'd wait till the warranty was up on the vehicle, before I'd throw that resistor in, but with a good, well-breathing, intake & exhaust, that resistor might add an additional 4-6 horsepower, whereas by itself, you'd just be wasting time & money, for something you'd never feel, or even notice a difference.
Hope this helps...
