Ok well i have a question about these.I know when spoon made them they made them for the ef8 and the ef9,but will they fit the usdm si airboxes?? If they don't,how hard would it be to modify the airbox?? Any info helps me out,thanks guys.

 

i do not think so

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by mrspeaker &raquo;</TD></TR><TR><TD CLASS="quote">why not just go too autozone and pick up a K&N drop-in filter..??</TD></TR></TABLE> theres a reason why a lot of "aftermarket" intake systems use K&N

 

And there is a reason why comptech and spoon use foam

 

also those foam types deteriorate faster

 

ok well i didn't ask for opinions on what kind of filter i asked if it would fit the usdm airbox........its not just for the horsepower,and none of you guys have dyno sheets on these anyways so theres no reason to argue over that.Back to the point,does it fit the airbox!?

 

No. u need the jdm si-r airbox
