Billet intake manifold - N14 / N18



Billet aluminium manifold made on a CNC machine to insure perfect flow and fitment. 

Provided with high quality Lazer cut Teflon gaskets for the throttle body, manifold and joining sections. 

You will also be provided with some extra vacuum/boost nipples of various different sizes and some bungs too. 

Flow tested to 100psi...

Centerfeed or side feed? - the side feed requires either a brake booster delete for ease of fitment or a shorter master cylinder. The OEM one can be shaved down but very stiff engine mounts will be needed to avoid contact under load. The centerfeed fits without any modifications. The sidefeed has a larger capacity and will flow smoother (better response), ideal for racecars or big turbo builds. 

Fitting instructions:

Removing your old manifold; there is a hidden bolt right below it, 10mm and extension are needed. 13mm nuts for the 5 manifold bolts. Unhook the 2 electrical connectors from the brackets and the PCV pipe frommthe valve cover. There is another breather attached to the right hand side of the manifold that needs disconnecting, same kind of clip as the ocv hose. Disconnect the throttle body connector and remove the manifold.

You will need the 2 large nipple fitting for the PCV breather and the fuel breather - the 2 hard lines that use push fit connectors need to be cut and replaced with silicone hose provided. 

We recommend 1 boost nipple tap instead of having the sandwich plate on the sensor. You will be left with 2 spare port that can be plugged or used. 

A coupler kit can be purchased to connect up to your original boost pipe as the throttle body location will change from standard. 

These are custom manufactured to order, please allow 3 - 4 weeks manufacture time.


The unit comes in a natural silver finish but can be painted in most solid colours, let us know what you would like in the notes section.

    Car modification laws in the UK and elsewhere are in place to ensure drivers who want to enhance their vehicles adhere to certain safety standards. While modifications are a great way to alter the look and performance of a car, some may also affect the handling and overall safety of the vehicle on the road.

    You may need to inform your insurance company of any modifications made to your car – whether they were already installed when you purchased the vehicle or if you have done them yourself. If you don’t tell your insurer, any future claim you make could be turned down. Worse still, your insurance could be completely invalidated. Modifications carried out to any car may affect the vehicle manufacturers warranty.
