I have a 2012 dodge avenger 2.4L and was thinking of putting a cold air intake cause 1) I travel 110 miles to and from for school and I heard it help with mpg 2) the horsepower and tourqe is fine for me but you can never have enough right?So my question is should I buy the mopar air intake for 400$ or a cheap one my chef said I can get on eBay for 50$
Save your money. 1) A cold air intake does nothing to improve the engine efficiency. Your mileage will remain the same, or even become worse. A cold air intake will allow cooler air to enter the engine, theoretically increasing the mass flow. More air - more gas - more power. In real life the computer will see the cooler air and actually INCREASE the fuel admitted and over fuel the engine. (Think of what the choke did in the olden days) Not exactly increasing the efficiency! 2) Extra horsepower? Why, you will only use the fractional and not noticeable extra hp when you floor the accelerator and that you can only do for a few sec or you will go waaay over the speed limit. Saving gas: Go easy on the accelerator. No sudden acceleration and no sudden slow downs. Learn to look a head and take your foot off the gas as the car ahead of you comes closer. Practice driving for as long as you can without ever touching the brakes. Look ahead and judge the traffic flow. (I said that, but you may have missed the point.) Do not waste your money on premium gas, 96 % of all cars in North America are designed for 87 octane gas. Putting higher octane in doesn't add any power nor increase the efficiency at all. (Close your eyes to the totally dumb and 100 % misleading gas company advertising, please)
A cold air inlet will not increase MPG. It increases HP at full throttle only. The develop in vigor is the outcomes of burning extra fuel, now not an expand in efficiency, or reduction of restrict. At all other power settings there is a different limit that is controlled through your correct foot.
