Hi all,

I’ve just bought an Audi A5 2009 2.0tdi coupe and was looking at changing the air intake to a performance one like k and n but can not find any ones that fit, does it matter if the intake was designed for petrol?

In effect ba filter is a filter abd you'd need one that has the same airflow capabilities or better. The main problem you.kight have is the maf mounting point will probably be different from the petrol and at which point it won't work.
