Air filters in line

[Jenson87]

In Mays issue of Sprint, there is a great spread on Adam AJP rebuild, his pictures show twin inline air filters, which I think looks awesome
I just wondered any anyone knew advantages or disadvantages.
If Adam sees this and wants to reach out to me please do, I would love to know more

That setup was designed and made by me.

I saw a mate's 400bhp Cerb lose 10bhp when the standard (new) air filter was fitted. The standard filter is a bit crap, and supported with chicken wire (mesh is bad for airflow). Cone filters left to their own devices in the bay suck in lots of hot air. My mate then "bodged" together a cold air feed/enclosed setup which seemed to work well, so I set about finding a big cone filter to feed each bank and designed/printed an enclosure for them, being sympathetic to airflow, to be fed only with cold air from the the standard airbox (with the mesh cut out).

Cheers dude, appreciate the reply. That explains why I could find any parts like this for sale.
I'm currently undergoing a full rebuild, I may pinch with pride this idea if that's ok.
