K&N Heavy Duty Canister Air Filters for Large Vehicle Performance
- 18 Aug 2010
K&N's new HD (heavy duty) 90 degree canister air filters are designed to have the efficiency
of standard OEM replacement HD air filters but they flow up to 15% more air.
The synthetic filter material in these filters is designed to filter air in a specific direction. Air flows in through the red side and out through the white side. Part numbers that end in an "S" have a standard flow filter design where the air flows in from the outside of the filter and out through the bottom base. Part numbers that end with an "R" have a reverse flow filter design where the air flows into the bottom base and out through the outside of the filter. Basically all of the reverse flow filters are engineered to flow the air through the inside to the outside opposite that of the standard flow models. The hybrid synthetic material in these air filters provide excellent filtration, engine protection, and long intervals between cleaning through depth loading. The synthetic filter media is designed to depth load dirt and contaminants into the filter itself. This is unlike most disposable air filters which only collect dirt and dust on the outer filtration surface. A key feature of K&N's 38-2001S, 38-2001R, 38-2002S, and 38-2002R is the ease by which they are cleaned. Unlike other K&N products that require gentle washing, K&N's HD canister air filters are just removed from their mounting canister and soaked with cleaner on the colored side of the filter, then washed thoroughly with a power sprayer on the inside surface for standard flow models and on the outside surface for reverse flow designs until all of the cleaner and dirt is removed. After drying, this quick and easy clean filter is ready to be reused. These filters are designed to last for 300,000 miles. Heavy duty trucks and other large sized vehicles that use corresponding filters in the cross reference table below can benefit from K&N's new HD 90 degree canister filters.
