4" K&n Filter

[TURBOGTA1]

I NEED A 4" K&N AIR FILTER SET UP, FOR I WAS RUNNING A 4" PIPE OFF TURBO TO A 3.5" LSI AIR FLOW SENSOR, INTO A 3.5" K&N FILTER, AND NOW ELIMINATING THE LSI SENSOR FOR A F.A.S.T SYSTEM!!
ANYONE HAVE SOMETHING TO SOLVE THIS PROBLEM!!!

just hook your 4" K&N onto the 4" pipe coming off the turbo......

you can get 4" filters all over the place.......
