Found the site while looking for Chrysler Concord sites. By the way, there are none of those. I have a Candy Apple red 1999 Concorde LXI (35,000 miles) with the 3.2 liter engine. Based on the advise on your site, I have change the air filter to a K&N. I feel that the car has definitely gain horsepower due to it. Currently, I am considering canging the air intake to the L-Intake and maybe change the exhast to a higher performance system. Finally, I look forward to your recomendations for improving braking performance.
