The Honda Accord has been in production since 1976 and is sold around the world. The Accord started out as low-emission, fuel-efficient car and was the first Japanese car to be built in the U.S. Originally a midsize car, the North American version is now a full-size car. Although not initially designed with speed and power in mind, you can add horsepower to the engine with a few after-sales modifications.
Change the factory exhaust system for a performance one that expels air more efficiently and does not allow the back flow of hot air, which can contaminate the engine. Changing the muffler to one with a larger diameter allows the air to flow out more quickly, which means that the engine stays cooler and therefore is able to create more power.
Replace the standard air filter with a high-flow version which opens up to let more air into the engine and boost fuel combustion. You should check the air filter regularly anyway and replace it if it looks dirty, so upgrade to a performance filter instead of a regular one.
Install performance spark plugs to give the engine a better start from the moment the engine is cranked. Just like the air filter, the spark plugs should be checked regularly (every month) so if they need changing, put in performance ones rather than standard.
Install a performance chip which immediately increases the power of your engine by automatically adjusting the air flow and the fuel burn but also allows for the downloading of further modifications at a later date. The software can be a little complicated though, so this might be one job best left to the professionals.
