I bought a K&N filter (E-2475) for my Syncro to replace the Big Syncro Heavy
Duty Table Top Conversation Piece type filter that was in it. When I ordered
it I specifically asked if it was for the Syncro Vanagon and was assured it
was. However, upon recieving it, it was sized for the standard Vanagon filter-
round -about 6.5 inches in diameter by 3.5 incher high.
Now, the Syncro Heavy duty filter is an oblong 10 x 7.25 inches shape by 3.5
inches high and has pleats of filter paper that are about1.375 inches wide as
opposed to the K&N�s pleats that are about 1 inch wide. Also there are about 3
pleats per inch on the K&N and about 7 pleats per inch on the Syncro HD
filter. So, I think that the K&N probably has better air flow, but I would bet
that the stock Syncro HD filter filters better, maybe not for as long, but
better than the K&N. And maybe even it has more flow due to more surface area.
Anyway I am going to get in touch with K&N and ask if they could better fit
the airbox like th Syncro HD filter with something else, meanwhile I�m still
using the HD filter which is actually very good.
