I ran the K&N open 14x 2.75" last year and part of this year with the
underhood pad. I have since replaced it with a ram/cold air box (from AIS)
which has two snorkels for 4" ducts ... one going to right of the rad
on the passenger side and the other temporarily going to the hole (by the
battery) in the fender on driver's side. I'm using a K&N 14 x ~2.82"
filter (I don't have a part number but may be able to find it ... it's
listed for a late 60's or early 70's Chev muscle car). Anything that
will lower the temp. of the incoming air is a positive but don't expect
to see significant gains on the track. If anything, trap mph will
benefit more than ETs ... just my experiences.
