Understanding Bolt-Ons
Bolt-ons are aftermarket parts that can be added to your vehicle without the need for extensive modifications. These upgrades typically enhance performance by improving airflow, increasing fuel efficiency, and optimizing engine output. For the Pontiac GTO, several bolt-on options can significantly boost horsepower.
Essential Bolt-On Upgrades
- Cold Air Intake
- Cat-Back Exhaust System
- Headers
- ECU Tune
Cold Air Intake
A cold air intake system replaces the factory air intake, allowing for cooler, denser air to enter the engine. This upgrade can provide significant horsepower gains, typically around 10-15 hp. Popular brands include K&N and Airaid, with prices ranging from $200 to $300.
Cat-Back Exhaust System
A cat-back exhaust system improves exhaust flow, reducing back pressure and enhancing engine performance. This modification can yield an additional 15-20 hp. Brands like Borla and MagnaFlow offer systems priced between $400 and $600.
Headers
Upgrading to performance headers can further improve exhaust flow. This modification can add another 10-15 hp, depending on the setup. Expect to spend around $300 to $500 for a quality set of headers.
ECU Tune
A performance ECU tune optimizes your engine’s parameters to take full advantage of the new bolt-ons. This upgrade can net an additional 20-30 hp. Tuning options are available from companies like HP Tuners and DiabloSport, generally costing between $300 and $400.
