Theses where my thoughts when I designed these vents and views of what people wanted on Facebook to help with design. Because what I like might not be what others like, it helps to make a good product.

I have land rover defender and wanted some nice strong CNC machined bonnets vents. Many are not true aluminium billet bonnet vents, they screw stainless steel mesh underneath the outer rim. Doing that make the inner mesh smaller as they have to fit into the wing. I don’t like that idea rather it had the same size outer rim as stock. It seems a shame when you pay all that money for a billet, and not use it to make the inner mesh. I know why they do this, as it saves a lot of machining time, but I’d rather it looked good. I like the honeycomb mesh and Facebook helped with this. I wanted to chamfer the edges to catch the light, and give a 3d depth to the vent. Also, I wanted no flow restriction keeping maximum size possible. I also wanted depth to the vent, and not just being a flat plate, so I’ll add border with radius. It will take a lot longer to machine an item like this but really feel it will look so much better for it.

The Vents are 10mm thick made out of high quality 6082 billet aluminium

The honeycomb mesh is deep in depth, CNC machined in a custom Jigs. This helps catch the light and makes them pop in the light. I have videos of this on Facebook, Instagram and TikTok.

Being honeycomb mesh and using the standard border size, the inner area is much bigger than many aftermarket designs. This help with flow and probably the highest flow in the market performance wise.

The mounting holes are machined for the Torx pin security stainless steel screws, they are supplied with the vents.   

You won’t have to worry about washing your defender or using screen wash. You can use TFR (Traffic Film Remover) and not worry who washes your Land Rover by using Cerakote coatings.

Every part that is Cerakoted is done in house, has to be cleaned first. Then the part in cleaned with washing up liquid. Then is blown down with compressed air. It is then left for some time to make sure it dry. I then spray the part with a special Cerakote spray gun in a spray booth. Then the parts are left to go hard and flatten. It’s a very thin coating which is used on many high-end products. It gives a very smooth slippery finish to item.

If you want a colour, I don’t stock in Cerakote there is a charge of £35.00 plus vat for custom colour which I order in. This should be enough to coat a whole set of hinges for Defender.
