removing air box

while cleaning the air filter on my 146 the other day managed to drop a bolt
down by the airbox, had to move the air filter housing a little to get to
it! , anyway when i'd finished and put it all back together i noticed a 1"
gap between the air pipe that goes from the air filter box to the bit that
eventually goes to the front of the car somewhere! guess i didn't put it
back together properly, altho, result is the car seems to pull a bit better
seeing as i guess it's now taking more air in

how can i go about removing all the boxe's n bits that go to the front of
the car, so i can have just one pipe that goes to the airbox? had a quick
look yesterday but can't even work out where it all goes, think it goes into
a big oblong box, not even sure where the air intake is!

well, the air-intake is located somewhere behind the bumper and if my mechanic is not lying, it is facing the left front tyre. I think it is going to be messy. You probably have to remove the front bumper to remove it.

I'm assuming you mean the air intake box that you plonk the carboard air filter into, you can rip this clean out in favour of another air filter, k&N or similar, Jano says the carbon air filter is the best and gives you low end grunt, the K&N filter will kick in after 3.5k revs...or use one of your stockings to get you from a to b.

take great care to prevent water sucked in by a rerouted airintake !!!! Alfa has done a good job preventing just that by placing the intake where it is now. In wet climates (UK, Holland etc) you can suffer a hydrocrash...

Leave the cone filters to the Max Power boys!

They have been proven time and time again do reduce performance rather than enhance it. This don't matter to the Maxy Pee boys as a 1.2 Nova is slow regardless of what you do to to it, except driving it vertically down a cliff...

thanks for that guys, i've already got a BMC filter in which made a great difference.

where the gap just in front of the airbox is it takes in more air and the engine feels better, but i know that gap isn't good where it is as it will take in hot air as well (if it gets warmer!)

think this looks like a good idea

just not to keen on the thought of taking the front bumper off tho, might see if my local alfa bloke can do it for a couple of quid ;-)

Looks like an obvious mod.! Great stuff, cheap, DIY job, and probably just as effective as cones and what have you! The bumper cant be too difficult to remove, a handful of bolts and a few wires!

Thanks for the tip!
