Just installed an Auto Zone pipe and K & N filter on a '96 SSE L36 series II. It has the single washer fluid jug but the PCM was in the way. I pulled the box, removed the plastic mount and laid it on it'* side with some padded material below it to protect wires. Also re-routed one line coming from the charcoal canister.
Auto Zone pipe part # 8219 $42.00 (cut down by 4" for my application)
K & N RX-4750 from AJ USA $49.00
Silicone 4" - 3" reducer part number PWRR40-300/400 $26.00
$117.00 for parts and about 2.5 hours to install. That covers everything but the heat shield which will have to wait for another day.
I also found that a small air die-grinder with a 1/2" machine bit works very nice for enlarging the "air intake temp. sensor" hole in the back of the K & N filter. My bit was just slightly less than 1/2" dia. and the sensor fit nice and snug. Word of caution. Make sure you carefully clean all rubber residue from inside the filter before installing.
