A new 2007 Acura TL front bumper costs between $200 and $350, depending on the quality of the bumper in question. Replacing the stock bumper would be about $200, while upgrading to an aftermarket bumper of higher-quality materials could cost up to $350.
Keep in mind, though, that that $200-$350 will only cover the cost of the bumper itself. If you want to have a professional install it for you, you’ll have to pay another $100-$300 in labor fees–meaning the total cost could be as much as $650.
