I have a BD X-intake w/ a K&N filter. The K&N is 3 yrs old and is all beat to crap and back and I want to replace with an AFE. I need to know how big the hole is in the AFE where it attaches to the Stage 2 AFE setup? Does anyone know?

 

AFE makes several different filters, so they might have another one that will work for your application. Let me know your sizing that you need and I will let you know what they offer.

 

Thanks,
I'll measure it tomorrow.... I thought is was about 5 " though.... I'll see if I can check the K&N website.

 

I think this is it.... so it's inside flange dia. is 6", However, I'm looking for one a little shorter that will fit in my box better.... 10 " length is too long.
