Product details
Weldspeed Hyundai N Intake Manifold to suit Theta II G4KH 2.0L Theta II G4KH 2.0L (i30N Hatch & Sedan, Elantra N, Kona N)
Ordered as needed, this is not an item we carry stock of
Representing a clean-slate design with the aim of improving upon the OEM Intake Manifold in as many ways as possible.
With increased plenum volume, optimised runner geometry for low-midrange torque output & improved volumetric efficiency at higher engine speeds.
Additionally, we have incorporated the provision for port injection for those who wish to surpass the capability of the OEM direct injection system.
Back-to-back dyno testing has shown a significant increase in spool-up & low-end torque. Peak torque was also achieved earlier than with the OEM Intake.
*Tested on "Facelift" engine/turbo combination
In an attempt to reduce complexity and aiding the engine to breathe further, the restrictive tumble vane system incorporated into the OEM manifold has been eliminated and as such, doing so will require the ECU to be remapped by a calibrator/tuner and have the actuator assembly to be removed from the engine compartment. Please contact us if you require more information on this.
This intake manifold is a no-compromise performance part that is specifically designed to increase engine performance with improved runner length and larger plenum volume. A significant amount of CFD time was spent ensuring that each cylinder received no greater than 1% variance in air flow all while maintaining the original throttle body location.
Designed for those wanting take their engine to the next level, an optional fuel rail kit is also available to surpass the capability of the OEM direct injection system. Raising the power ceiling above and beyond the factory fuel limitation.
Please note there is extra items required for installation, we are working on a kit for this at the moment
