Most standard "bolt-on" kits deliver approximately a 25% increase in both horsepower and torque at roughly 6 psi of boost . More aggressive twin-screw setups from manufacturers like Bullet Cars can reach up to 45% power increases .

While some low-boost kits (under 6 psi) run without intercoolers, high-output systems often incorporate water-to-air intercoolers to maintain safe intake temperatures.

Use high-efficiency coatings (like APC) to minimize heat and maximize air density.

Most kits are designed for OEM-like fitment and can be installed by an enthusiast in a weekend or a professional in one day.
