On some cars K&N etc make kits with pipes/ hoses to refit the MAF sensor
In general the cone filter is a waste of time - it loses power because it draws warm air from under the bonnet (cooler air = more oxegen per cc = more power) and the most it achieves is more noise
Heat sheilds and cool air intakes do not work if the cone filter can draw any warm, underbonnet air
A lot of manufacturers now make encapsulated cone filters now (BMC, pipercross(viper)) to combat this problem
Fully encapsulated pipercross viper cone filter/ induction kit -
More info -
BMC cda (carbon dynamic airbox) -
Even so often the stock airbox outperforms these - this is because the stock airbox is often "tuned" or "matched" to the engine to boost torque a little (the aftermarket "performance" filters are not)
You may be better fitting a panel filter from K&N or pipercross -
