They are the same shape as all the 4.2 airboxes that I have seen but he probably filled in the ripples with filler and sprayed them up to look like 4.5's. When you next take them off look inside and see if its' ripply inside.

He/She may have added 1kg to the weight of your car, so best go on a diet for a day...

What about inside the boxes, are they ripply inside when you look through the trumpets?

No.They are as straight on the inside, as they are on the outside,with not a hint of filler in sight.

Obviously someone has made them up 'straight' because they wanted them to be sprayed the same colour as the car.But I wouldnt worry about why they are different, they are just different.
Of course you can always ring the Factory tomorrow and ask them if they were a Special order. laughlaugh

PS Thats a point, I wonder if the records still exist??

Thats more like it.Someone with some sort of answer.Ive got two dates of first registration??? one being April 96,the other June 96?? Its the 13th Cerbera made and was originally Rosso pearl red.One other thing i thought was strange was the fact that apart from the inlet boxs,all the other Cerbs ive seen show a 220mph speedo.Mine shows 180mph?? The colour change was done by the previous owner to me.He had the car completely gutted.Glass out,doors,bonnet,boot off,interior stripped and resprayed in the present colour.

Could it be to do with the fact that the Cerb was originaly intended to have the RV8 power plant.Couldnt really get more than 170mph out of that???

I thought that all 4.2s upto 1998ish had speedos that read upto 180mph.....could be wrong though..

If you look at the picture at the top of page 2, it shows a very early 4.2 (1995), it too has the same airbox, so this backs up what Andy has said.

Im going from memory,but i thought that the original plan was for the Cerb to have the RV8 powerplant,but it wasnt until the introduction of the AJP in to the challenge series and the potential displayed,that the idea of a RV8 in the Cerb was binned?
