If you're a speed fiend with a yen to go faster, faster in your Corvette, then you might want to consider the Callaway Corvette. It's a customized version of the standard Corvette that is available in limited amounts to certain dealers. Since it comes with a cold air intake to help boost performance and mileage, after you buy one you cand find out do cold air intakes increase mpg, and do cold air intakes void warranty guarantees. Well, since you'll be paying an additional $18.5K for your Callaway 'Vette and since it comes with a 3-year, 36,000-mile warranty, the answer to the question do cold air intakes void warranty guarantees, the answer would be a resounding "NO!". However, you may well ask, what do you get for the $18, 5000 you pay on top of the 'Vette's not insignificant price tag? You get your horsepower boosted up to 580, and according to Callaway's founder Reeves Calloway, "Our customer gets an individually built, uniquely styled automobile that can go from 0 to 60 mph in 3.3 seconds, runs the quarter-mile under 11 seconds, and delivers a top speed of 210 mph." With speeds like that, the next logical question to ask is: do cold air intakes increase mpg? I sure hope so, because at prices like these, you'll need to pinch pennies wherever you can.
