Easiest way to add horsepower 1996 mustang gt?

The easiest way to add horsepower to a 1996 Mustang GT is generally considered to be a cold air intake (CAI). This improves airflow to the engine, allowing it to breathe more efficiently and produce more power, albeit a relatively modest increase (typically 10-15 hp at the most, and sometimes less depending on other factors). Installation is usually straightforward, often involving minimal tools.

However, it's important to note:

* "Easiest" doesn't mean "best": While a CAI is simple to install, other modifications might yield significantly better horsepower gains but require more mechanical skill or professional installation.

* Other factors matter: The actual horsepower increase from a CAI will depend on the quality of the intake, your altitude, and other modifications already done to the car.

* Tuner Required (Possibly): Some CAIs may require a tune to get the full potential power gain and prevent potential issues.

While a CAI is the easiest *initial* step, for substantial horsepower increases, you'll likely need to consider more involved modifications such as:

* Exhaust system upgrades: Headers, high-flow cats, and a performance exhaust will dramatically improve exhaust flow.

* Tuning: A custom tune is crucial to optimize the engine's performance after making significant modifications. Without it, you risk harming your engine.

* Performance camshaft: A higher-lift camshaft improves valve timing and allows for greater airflow. This requires more mechanical knowledge and often other supporting mods.

In short, a CAI is the easiest *entry point*, but for serious horsepower gains, expect a more involved and potentially costly undertaking. Always research thoroughly and consider consulting with experienced Mustang mechanics or enthusiasts before starting any modifications.
