Just get a bit of 4" box section, weld ends on and cut the flanges out.

mine were 'proper' ones. designed using flow technology rather that making a box out of aluminium. taking resonance etc into account. made from machined cast alloy they looked like this:



although i do still have designs and tech drawings for the straight forward 'box' design if anyone wants them?

basically it'll only add power on a car that has a restricted inlet to begin with.

because the throttle body is situated on the passangers side of the engine.

by removing the standard inlet and making a 'coboid shape' inlet with the throttle body on the side where the airbox is the air has shorter distance to travel into the lower inlet.

heres a diagram of the one on my car

yellow line = mantzel air route

red line = standard inlet air route

mantzel air route is far shorter there fore better performance :D

got full working drawings, 3d models, graphs showing dimensions,

everything you need really to make these. i made quite a few and they worked well, but i dont need the money anymore and i lost interest.

you can have the lot if you want, £100.:P
