Imperial Home Page -> Imperials by Year -> 1990 -> Modifications
Even if you are not interested in car performance, racing, and so on with your Imperial, not all of the designs on these cars are worth keeping. Although these cars were built extremely well, there is still room for improvement at times. In the end these modifications don't just increase horsepower, but also help improve gas mileage.
NOTE: This information is presented as-is, and although we would like to say we are experts, we are not and any damage occurred as a result (either directly or indirectly) is due to the fault of the person who makes the actual modification. Also check local and state/federal laws and restrictions before changing the exhaust system, or emissions control system.
Here are a list of some modifications, all of which can work on either the 3.3 or 3.8L V6, unless noted otherwise.
