Hi guys Ive a 2001 clio that I got last year for £500. It runs ok and it just for getting me to work and back. And as its my first car I want something easy on the insurance

But something is confusing me. My air box came loose a few weeks ago so I took it off and forgot to put it and the filter back. But for some reason I am getting better MPG at the moment. I will know for certain in a few days but I think I am. Anyone know why and what is wrong?


Cheers
 
Jesus man, must be so much crap going in the engine. Really bad for the engine. Probably just a clogged old filter

No idea if the filter has ever been changed. Ill get one and change it at the weekend if its a bad idea running it without one :)

Think about how an engine works. Bits of metal moving very fast with very tight tolerances between them protected by a thin film of oil. Now think about throwing a handful of road grit in there. Air filters are there for a reason!

No, they are completely optional. Manufacturers could save many millions of pounds and free up a load of space under the bonnet if they realised this, but they have trouble thinking outside the (air)box. A bit of dust and grit is good for the engine anyway, just like having some fibre in your diet is good for your health.
 
I heard feeding some fine sand through your engine polishes the surfaces reducing friction and improving performance and mpg. Make sure you rev it hard though to ensure you blow it all the way through the system.

Added bonus; driving with no air filter near the beach is an inexpensive way of porting the inlet manifold and head.
 
You will get a marginal increase in performance, and probably a slight increase of MPG, somewhat offset by your engine expiring fairly soon.

Air filters are there for a good reason.
 
Air filters are a con by the big air filter conglomerates

Engines for these only cost £180, but an air filter is more than a fiver. By the time you've changed it 36 times you're worse off :(
 
You can replace the filter with a longer piece of pipe and scoop, located as low as possible to the ground to maximise water intake, which cools the engine for more mpgs.
 
The Dirt and dust getting into the engine and creating a fine layer on the cylinders sides. Due to the cylinders being slightly smaller the car requires less fuel to make it move (less fuel needed to ignite)

Eventually you should see gains of around 20%.
