Technical air box

eyebrows101 · Jan 29, 2011

ok, so here's my dilemma. i have just fixed my split breather pipe (i'm impressed with myself!) but i managed to nacker my air box in the process.(i'm not too chuffed about this!) . now, a new air box will cost it seems in the region of £100 but i could just get a K+N induction kit for £60. is this a wise move? i've heard there is a better make but i'm not doing it for performance reasons but i was wandering if there was any downside to the k+n? mpg reduction?

any help greatly appreciated. thanks.

You will also need to declare the K&N to your insurance company as it would be a modification which could obviously increase your premium.

i snapped off the part that the breather connects to. i could probably fix it with some epoxy putty but i need to use the car every day and it might take a bit too long to dry, i don't know.

when you say bad times, what do you mean exactly. i'm not that bright when it comes to engines unfortunately.

i should add, it's a 1.2 active 2007. don't know if it makes any difference or not.

hi
sorry for being vague

an engine runs much better if it has cold air coming in as it is much denser.
therefore with the K&N filter sitting onto of the intake manifold it will draw in hot air that the engine gives off so decreasing performance.

and tbh on the 1.2 (i have one aswell

) u need all the power u can get

would running a large hose from behind the grille to the cone solve that problem?

not really unless its enclosed in a box or you mount the air filter closer to the front via a length of silicone hose

Nope always take the air filter to the cold air not the cold air to the filter.
