Which air filter?

12secondSY

Syty Killer :(
What size air filter will fit on the stock orange elbow if I move the filter behind the passenger side headlight. The battery will be gone and I will have an RPM A-A on also.
I need to know what the inlet size should be also(outside diameter of orange elbow) if anyone knows it off hand because I dont feel like going out in the cold and checking.
I was going to go with a conical K&N but I didnt know what length or inlet size to get.
Thanks.

8 inch cone K&N part number RE-0910:

The inlet on the stock orange elbow attaching to the turbo has an OD of *slightly* over 3 inches. I used a small scrap piece of 3 inch 304 SS tubing that was left over after I made a pipe to delete my ATR muffler. I expanded it slightly on the orange elbow side until the elbow was a snug fit on the adapter pipe. However, you could get away with not expanding it (I'm a little particular when I mod my truck). Got an 1/8" coupler from the hardware store and had it TIG welded to the side so that a barbed fitting could be attached for the PCV. A breather then got attached to the driver's side where the fill tube was at. Didn't have to do anything on the K&N side as it was a tight fit.
