I,m looking to buy a used APS induction kit. The I/D of the filter where it joins the Maf pipe is about 90mm and the length of the filter including the collar is 190mm. Does anyone know what kind of power this filter is good for? Thanks Steve.

 

Do you mean API or APS ??

 

Sorry, meant APS. Steve.

 

If the in wing kit. ive seen them run 505bhp on a bug sti

 

Thanks Devious. It is the short ram kit as I have a Japspeed front mount and there is no room for the inner wing kit.
