Since the moment it burst on the scene in 2011 the KTM Duke 125 has been crowned one of the most dramatically unique motorcycles to grace the complicated roads of India. The entry level single-cylinder machine is manufactured in India by KTM's partner, Bajaj Auto. The Duke 125 successfully addressed KTM's most youthful entry-level target group, which developed as a result of the new EU regulations that allow 16-year-olds to ride 125cc bikes with a maximum horsepower of 15 horsepower. Interestingly however, KTM dealer statistics showed an even split in 125 buyers between 16-18 year-olds, and everyone older than 18.

KTM introduced the Duke 200 the following year and is one of the most impressively detailed small displacement machines available anywhere. It has clearly raised the bar for performance motorcycles in India. The Duke 200 offers a sophisticatedly engineered, featherweight chassis with high-quality components all around and first-class brakes to maximize fun and rider safety. The refined four-stroke, single cylinder engine with fuel injection and six-gear transmission provides a surprisingly "big bike" feel and attitude.

Heavy Duty Commercial Grade Diesel Air Filter
Heavy Duty Commercial Grade Diesel Air Filter
K&N's replacement air filter part 38-2026S is a drop in replacement for heavy duty commercial grade trucks and busses. The 38-2026S and other K&N heavy duty air filters are made to replace the standard factory air filter in your truck's air cleaner housing. The 38-2026S is made with K&N's contemporary non-woven lofted synthetic media which is held together with a signature epoxy coated aluminum wire mesh. The wire mesh encases the synthetic pleats creating a super strong filter core. This core is supported further with a ridged metal casing powder coated black. The synthetic air filter media traps harmful particles while its low restriction helps your engine run better.

A few of the trucks and busses the 38-2026S may be used on are listed below, however, make sure you cross reference your existing air filter to make sure the 38-2026S will fit your truck or bus.

  • Krystal Koach International 3200 Bus with IH DT466E Engine or VT-365 Engine
  • International 3200IM Bus Chassis with VT-365 Engine
  • International 4100 Truck with VT-365 Engine

The K&N 38-2026S is a cleanable and reusable air filter that can be washed, dried and re-installed. This filter can be cleaned using our simple heavy duty degreaser 99-0638 with a water hose, power washer or truck washing equipment. Once the filter is dry it can be re-installed into the air cleaner housing as no oil is required. These heavy duty filters are very easy to clean. This standard flow air filter should be cleaned from the inside out opposite of the way the air flows.

The 38-2026S heavy duty air filter has a radial seal to insure maximum filtration. The round rubber flange seals to your air box by pressing firmly against it. The radial seal forces air to go through the filter media and not around it. This filter comes with a 3 year 300,000 mile warranty and should be cleaned once a year, every 100,000 miles or when your restiction guage says it's time. With the 38-2026S you will save money by not throwing it away like disposable air filters.
