Replace and/or Upgrade Your Air Filter
During the life of your engine, thousands of cubic feet of air will pass through the engine cylinders. Dust and other material in the engine can cause excessive wear and operating problems. It’s imperative that you keep air filters clean by regularly replacing them.
To further enhance performance, upgrade to a performance air filter, which can free up an additional 2 to 3 horsepower. While not a tremendous power gain, the relatively low cost of a filter and ease of installation (about 5 minutes) more than make up for it.
Use Higher Octane Gas or an Octane Booster
Go for the good stuff the next time you’re at the pump. Depending on your vehicle, high octane gasoline can provide an increase in horsepower. Even a marginal gain in switching from the lowest octane gasoline to the highest octane may be worth a few extra pennies at the pump to you.
For those who want to see a more measurable increase in power, a racing blend of gasoline will work well or one of the numerous brands of octane booster commonly available at auto parts stores.
Upgrading your gas, lubricants and air filter are a cheap and easy way to increase horsepower. These simple steps will also extend the life of your engine and help prevent expensive repairs.
