double layer air box insert

Hi,

If I was to put a double layer insert into my airbox would I have to rejet?

cheers

 

i put one into mine? and i didnt. although it give you more air flow so could be possible

 

Surely that would just suffocate it?!
I lost my air filter last week en route to a mechanic, he put a thin rag over and it kept boggin out

 

no, its made from a special material, there made by polini n stuff... its same thickness as a normal air filter, just 2 different types of material one to stop water, n one to stop the micros and still allow air to flow freely
