What you think either a bmc cda

or this one

Does any body actually think there is going to be a difference between the two.

bmc/cda dont make those kits themselves they, like many other bolt mod companies, just buy in components made elsewhere and stick a fancy label on it and triple the price, the thieves!!!!!

dont be silly just go for the cheap one! a bmc sticker doesnt make it any better does it!

or you can get one from

Urban X Open Funnel Induction Kit - swuxcf

the bmc ones are better designed out of the box, but the cheaper ones can be modified to flow better.

adding half a jug

and some filler (or glassfibre paste) to the filter

can reduce the pressure drop across the filter to less than 1/3 of it without the additions.

if it makes any difference on the car, I dont know, but I doubt you'd be able to tell
