Someone suggested we use a K&N air filter for improved breathing on our Avanti's, and it could be washed and reinstalled. K&N says that they do not have an "OEM" replacement. Suggestions and or comments, please. don --------------------------------------- don: There was a post on this list a couple of months ago where someone put a K&N air filter on their R2 Avanti; They said that they used K&N filter #E-4600..... it said the filter is the right size for the air filter holder (can) and is 6'' tall, so it equals the 2 Fram CA102PL filters normally used. Lew --------------------------------------- For the R-2, you can use two K & N # E-4590, or one # E-4600. One 4600 will cost less than two 4590's, but you will have to unbolt the air cleaner housing in order to provide enough room to install the 6" high filter. I don't know the specs for the R-1, but if you measure the inside and outside diameter, and the height, I'm sure that K & N has a matching filter. Speed shops (and even Pep Boys) have catalogs with the filters listed by size. Bob Ziff --------------------------------------- I just got my K&N E-4600 unit. It is 6 3/8" tall, 6 1/2" o.d. and 4" i.d. and fits into the R2 air cleaner can with just a slight adjustment to the lip of the steel mesh centre in the can so as to slip it in - tight enough for the girls I go with. Cost me $58 Cdn including tax. One takes the place of the two 3" FRAM 102's you would normally use. Keith --------------------------------------- Ki&N for the R1 r#/ E1560
