Re: Alfa GT K&N Panel Filter
Its a filter....
The K&N doesnt filter as well as standard (check the relative specifcations) and depending on the conditions it can indeed cause MAF failures, despite K&N's protestations, all oiled filters are the same.
The turbo diesels operate in a sufeit of air anyway, thats why the remaps work.
Also you cant dyno test an air filter as the intake characeristics are affected by the dynamic pressures around the moving vehicle.
Alfa Romeo induction systems are all tuned and well designed, with large surface area filters (larger than most of the aftermarket 'performance' items) The biggest restriction in the GT Jtd inlet is the pipe up from the airbox which is a bit pants to be honest.
Dont waste your time or risk your MAF/Turbo. Use an OE spec dry filter and swap it regularly.
