pipercross panel filter
 

Hi Guys i've brought a pipercross panel filter to go with my full decat system on my 2001 wrx ready for mapping by mr mapper next thursday was just wondering what people thought of the filter if anything?
thanks

As long as its not loaded with oil, it won't do any harm.

would i be better leaving it out or do you think that it will help with the mapping?

Green Panel Filter gets my vote.

They are well made filters, i would leave it on over standard filter.
