I am selling a used 1LE elbow and K&N filter that I used on a LT1 swap. I used it on a 93, but it will easily fit a MAF swap by moving the filter. It has the vaccum hookup for the opti in it I just have it plugged with a vaccum cap. Great shape. I used the Air temp sensor with the new air tube so you will need to use a stock one. 75 shipped in the lower 48. I take paypal to rickyzZ28@hotmail.com.
