Mercury Grand-Marquis Performance Chips
If you're the proud owner of a Mercury Grand Marquis, you probably enjoy the spacious interior of this large car. However, it's not as maneuverable as its smaller competitors. Due to its large frame, the Grand Marquis isn't nearly as sporty or zippy as its American and Japanese competitors. The good news is that you can boost your sedan's performance. Install one of our Mercury Grand Marquis performance chips, and you'll find that you can pull some extra power from your engine and boost efficiency under the hood for a more satisfying ride.
Mercury Grand Marquis performance chips are designed to boost the performance of your car's engine. The Grand Marquis chip plugs right into your car's onboard computer, and reboots and reprograms your vehicle's calibrations so that the engine receives more of the air and gasoline it needs to work well. Your Grand Marquis now has more power, and in return, you get better driving experience. Our stock performance chips are simple to install, and can be completed in as little as 20 minutes. And, because 99% of our Mercury products ship for free, upgrading your Grand Marquis couldn't be easier.
