all '86-'91 vanagons have a "snorkel" "cold air intake" in the right rear air
scoop, leading down thru a hose to the factory airbox.  (i bet half of you
didnt even know this)  has anyone ever tried to retrofit one of these setups to
a 80-85 van?  would it improve performance? (colder, denser air entering the
TB = more HP)  or would the improvement be so minimal it wouldnt be worth the
trouble?
on the stock 86 up air intake snorkel in the RR scoop, the snorkel is turned
away from the opening, so rain doesnt come in..  even tho at the bottom of the
hose, where it turns to go to the engine (behind the RR taillight) there is a
"p trap" and drain hole so it can let water out..   i have like 3 of these
setups here (3 '86 up parts vans) and was thinking of adding one to my '84 but
do u think it would make a difference?
