Holley Proven Packages

Holley has taken the most popular and effective performance upgrades for your vehicle, including air intakes, exhaust systems, tuners, and headers (specific applications), and packaged them together in easy to select Proven Packages. These packages are track and dyno-tested, so you know what level of performance to expect. Most applications have three levels of packages to select from, allowing you to not only achieve the level of performance you desire, but they also act as a tested road map for future upgrades.

Cold Air Intakes

  • Proven Packages include replacement panel filters, open element performance intakes, or sealed cold air intakes
  • These intakes ensure that your engine is not starved for airflow, increasing power and efficiency
  • These filters are serviceable, meaning you will not ever have to buy another air filter with proper maintenance
  • Open element and sealed cold air systems add a custom look under the hood of your vehicle
  • Sealed cold air intakes are fed air from outside of the engine bay for a cooler, denser air charge resulting in even more performance gains

Exhaust Systems

  • Proven packages include either axle-back or cat-back exhaust systems that are emissions-compliant
  • These systems are constructed of 304 or 409 grade stainless steel for added strength and durability
  • Mandrel bent pipes maximize the exhaust flow for increased performance
  • Factory mounting points are utilized for easy installation and a secure fit
  • Hardware included for an at home installation
  • If your vehicle has exhaust cutouts in the factory bumper, we have systems that utilize those exits for a clean, professional looking installation

Tuners

  • Proven packages include either handheld or dash-mounted tuners
  • Most use your factory OBDII port for plug and play tuning in a matter of minutes
  • Our selections of tuners provide you with a variety of tunes that will allow you to optimize your vehicles tuning parameters for your use
  • Tunes can be changed quickly so your vehicle will be performing at its best, no matter the situation
  • You can read, diagnose, and clear diagnostic trouble codes for easy troubleshooting
