Amsoil Oil Filter, Type 4 Engines (Stock Filter Location), AND Oil Filter Pumps, EAO34 is the finest conventional oil filter we have found for our aircooled VW engines (the cleanable ones are a pain). These filters are good for 25,000 miles before a replacement, 15,000 in "Severe" conditions. Yes these cost more than "normal" oil filters, but we feel they are worth it! This filter is 4 1/2" Long, and a good choice for filter-pump oil pumps!
You'll use a 76mm Filter Wrench for this filter.
The can is VERY strong so it won't blow out, and the filtration is as good as you can get.
AMSOIL Ea Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the automotive/light-truck market. Ea Oil Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns, while competitive filters containing conventional cellulose media range from 40 to 80 percent efficiency.
AMSOIL Ea Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic nanofibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter does. Lower restriction decreases engine wear.
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines do. In fact, when used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one year, whichever comes first, depending on application and severity of service.
AMSOIL Ea Oil Filters are made with premium-grade full-synthetic media. The strictly controlled processing of this media ensures accurate filter construction and is what allows Ea Oil Filters to deliver higher capacity and efficiency along with better durability.
Over the service life of a conventional cellulose filter, hot oil will degrade the resins that bind the media. Ea Oil Filters’ full-synthetic media technology is resin-free. It uses a wire screen backing that is pleated with the media for superior strength.
Ea Oil Filters are constructed with HNBR gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting, premium-grade silicone anti-drain valve.
