Air Intake Components
Air intake components control how filtered air enters the engine, directly affecting throttle response, power output, and fuel efficiency. Upgrading the intake path from the filter to the throttle body is one of the most accessible performance modifications available for nearly any vehicle.Popular UpgradesCold air intake kits are the most common upgrade, relocating the filter to a cooler area of the engine bay and replacing the restrictive factory airbox with a mandrel-bent tube for improved flow. Short ram intakes keep the filter closer to the engine for a more compact installation while still outperforming stock setups. Replacement performance air filters let you upgrade within the factory airbox without changing any tubing, which works well for vehicles where airbox location is optimal.What performance gains can I expect from an air intake upgrade?Gains depend on the vehicle and existing intake setup. Most naturally aspirated vehicles see modest horsepower increases in the 5–15 h...
