Air filters Part 3
I was checking my air filter the other day, only recently having read some articles on the subject
I notice how tight and contorted the box is. I've read about drilling holes in the box etc etc, fitting K&N filter etc.
It struck me there seems almost no way of getting a real draft in there, save , dare I mention cutting a whole in the bonnet above the damned thing.
Ok don't panic, this may sound worse before it gets better but I noticed that the little air scoops fitted at the top of my neighbours J reg Rover 100 where exactly the right size and shape for this job. (Note N reg on rover 100 scoop diferent oval ones and not good)
So anyway this is the Madcap proposition:
Leave all existing Air box and tubing in situ. Remove lid from box. Cut large hole in box lid. Make homemade sponge filter to fit in lid. (Note ideal sponge filters can be bought from garden centres or aquatic centres, sold as pond filter sponges. usually in black or turqouse and available in a number of grades of fineness, those sold for Laguna filters look best)
Now original box it taking in air from above and below. Fit late model Metro/early Rover 100 air scoop above box in bonnet. Fit other side scoop to match.
Dispite the crappy nature of the Rover 100, I bet you can't remember how these scoops look, they are black, squarish with heavily lipped top edge, you'd never know where they were sourced from unless told. Other bonnet vents such as Pug 206 which may look groovy are angled all wrong and could not blent in with the car.
Oh, havent actualy done this by the way, but thought Id put this to someone else for discussion. Maybe if you realy want the added air flow and are using your alfa for track days or you need a new bonnet anyway you may give this a go. [img]eek.gif[/img]
