This is to Marlon, but anyones input is helpful. I took my standard panel filter out today, because the car sounded like it was gasping for air under heavy acceleration. It was nearly full of flies, leaves and sandy dust. It now sounds like it did before the summer.

But, what do you recon on removing the base of the filter box as marlon previously has done, or just go the whole hog with induction filter. Had one on my 33 16v, but it wer`nt cheap.

:confused:

I haven't noticed any real benefit using the Green Cotton induction kit over my modified airbox other than the kit is slightly quieter. Performance seems about the same. I did notice better performance when I initially modified the airbox.

Alfa puts in thousands of pounds (or what ever they use in Italy) to developed the air box so why would we take it to peices. :confused:
Get a K&N washerble panel filter and save your money and time. ;)

Sure Alfa spend loadsa dosh developing the intake system, but at the end of the day, it's a compromise between high and low end power.
My car may have suffered a little at the bottom end (although with all the stuff done to it and replaced, it is far better than when I bought it), but I mostly have the engine buzzing at high revs, where I do notice a difference. The benefits will depend on how you drive the car and the condition of other parts ie plugs, leads, exhaust etc etc.
I do agree with the good panel filter though, I found my BMC panel filter to much better than the standard, but only after I cut the box up which suits my style of driving.

I have a 97' airfilter without the pipe going across the front of the engine bay and my 95' has one going across the front of the engine bay.
I wonder what the difference will be when they are both back on the road with a K&N panel filter in them. :rolleyes:

I suspect the one with the pipe will be better. The one without the pipe doesn't have a "direct" cold air feed, although the if the pipe is the same as the 8v and sits above the radiator, it is still pretty restricted, and gets hot, heating the air. Best bet is to reroute a pipe down to the front air dam.

Not only is the airbox there to help low end power, often the primary reason is to reduce intake noise. As many have noticed when you fit a cone filter the intake roar is too noisy even for the driver.

On my Yamaha TZ250 racebike, the intake noise on open carbs excedes the noise from the barely silenced pipes on full throttle. This gives you an idea as to what the manufacturer is up against when designing the car. Especialy considering todays stringent noise regs.

Some food for thought.

I agree Colin, the K&N kit I had was far too noisy. It was like driving with the AFM open to the wind. The Green Kit has a pipe which deadens the noise and it is fine. You'll get to hear it in Keswick. BTW, I had my modded box on at Knockhill so you'll already know how much noise that made.

If you want to see what the Green kit looks like, go to my post in the image lounge for Test Piccys of me Banger (or something like that)

I once had a Mk.2 Escort with Twin 40's and an ITG foam airfilter, and even though I had a single box competition exhaust system on it all you could here was the Carb's SUCKING. :rolleyes: :rolleyes:

I would stick with standard airbox............... my old Sud used to have a Westfield inlet manifold conversion with twin downdraught`s and K n N Filter`s and all you could hear was the air being sucked in :rolleyes: which muffled all the knocks and rattles :rolleyes: :D

Some used to say that the tree`s bent over as i passed them :p :p
