Ferrea
Ferrea offers standard size and oversized size in super allow or stainless steel.
Solid lifter
Running the stock hydraulic lifters with a shim is fine up to ~8500 rpm. Above that and / or for motorsport application, solid lifters are required.

Intake manifold
The stock intake manifold is designed to produce low-end torque to the detriment of high end torque, this give better acceleration and fuel economy for the general consumer.
Aftermarket intake manifold with their shorter runner, their bigger plenum and their flow design changes the torque curve allowing for more top-end power while loosing low-end torque.

For transversal application
One of the most efficient intake design for top-end power especially on turbo applications.
Althought, it's been reported on newer revisions that the rivet holding the logo plate could be causing small boost leaks.

SPA Performance
For transversal application Works with hydraulic power steering
JAAATT Engineering
For transversal application
While it's not an intake manifold, this billet runners give you the possibility to mount a RS3 / TT-RS plenum on a VW 07K
LPSFAB
For longitudinal application
Boost Brothers Garage (nine x engineering)
For longitudinal application (has been designed for Porsche 944)
Phenolic Intake gasket
Limit heat transfer from the cylinder head to the intake manifold. Recommended when using an aftermarket aluminium intake manifold.
