How to Increase Horsepower in a Ford Ranger?

I recently bought a Ford Ranger and I love the truck, but I feel like it's lacking in horsepower. What are some ways I can increase the horsepower in my Ford Ranger? I don't want to buy an expensive upgrade kit, but I'm willing to make some modifications myself. Any advice would be greatly appreciated!

One thing you can do is install a cold air intake. This will allow your engine to breathe in colder, denser air which will result in a slight horsepower increase.

Another option is to upgrade your exhaust system. A less restrictive exhaust will allow for better airflow and can also boost horsepower.

You can also consider changing your spark plugs and wires. This will result in a more efficient combustion process and can add a few extra horsepower.
