Hi I´m new in this and want to know the maintance schedule for my Super Liner wit a 350 2V E6 and 14615 fuller gearbox is any online help on this.

¿ K&N made some reusable airfilters Or any one else?

It won't hurt to have a look in there to make sure that everything is in good shape...all it will cost is some new gaskets to put her back together.
