Mac Trucks Get Reusable Performance Air Filter

K&N Heavy Duty air filter part number 38-2023S for Mac trucks
K&N Heavy Duty air filter part number 38-2023S for Mac trucks
Founded in 1900 by two brothers, Gus and Jack, Mack trucks have seen their fair share of rough terrain and brutal environments that eventually take their toll on any vehicle built with anything less than quality in mind. Its appearance and durability during World War I inspired British soldiers to dub Mack trucks with their mascot, the British Bulldog and as they say, the rest is history.

Over a century later, Mack trucks still prove their durability and display their trademark British Bulldog on nearly every truck that leaves their facility. Bound for harsh mining sites or long up-hill highway pulls, Mack trucks were built to withstand the abuse. Using the newest clean burning diesel technologies, Mack is one of the industry leaders in reduced emissions trucks.

Keeping a cleaner environment in mind, K&N offers a replacement HD air filter for various Mack trucks that utilize an under hood, radial seal air filter. K&N's 38-2023S HD (Heavy Duty) air filter is made of a robust, non-woven, synthetic material that is washable and reusable resulting in less waste ending up in landfills. This low restriction air filter provides outstanding air filtration and it is made to last.

Just as durable as a Mack truck, these filters can be cleaned using K&N Heavy Duty Filter Cleaner and a pressure washer set at its low setting. No filter oil is required so when you are done just let the filter dry. You can even use compressed air to help speed the drying process. This makes servicing the 38-2023S easy.

Backed by a 3 year 300,000 Mile Limited Warranty, the 38-2023S HD air filter offers great engine protection even under extreme driving conditions.

K&N's 38-2023S air filter replaces the following manufacturers' part numbers:

K&N Reusable Heavy Duty Air Filters Save Diesel Truck Drivers Time and Money

Heavy Duty Replacement Air Filter 38-2011S
Heavy Duty Replacement Air Filter 38-2011S
With the rising cost of fuel and maintenance typical "Big Rig Truck" and Class A motorhome owners look for ways to cut operating costs without sacrificing performance. K&N has some exciting news for these owners with their line of reusable high-flow heavy duty air filters. Purchasing replacement OEM air filters over and over is now a thing of the past. K&N's washable and reusable air filter solution can save time and money. K&N heavy duty air filters are easy to clean and do not require oil.

K&N parts 38-2011S and 38-2025S are examples of heavy duty reusable air filters for diesel vehicles. K&N's 38-2011S air filter is used on some Ford F650, some Freightliner L50 and L60 Trucks and some John Deere Equipment. K&N's 38-2025S air filter is used on some Volvo VN 430, VN 630, VN 670, VN 780, VNL 300, VNM and VT 880 trucks. To find the correct heavy duty air filter for your vehicle use K&N's Air Filter Cross Reference to select your existing air filter manufacturer and part to verify the correct K&N heavy duty air filter.

K&N heavy duty air filters have a directional flow hybrid air filtration medium made from non-woven synthetic material that operates with low restriction and offers excellent protection under some of the most extreme driving conditions. Less restriction means more power and better engine efficiency. This is a good thing when climbing steep grades or even crossing the Great Plains in a vehicle that weighs more than 15,000 pounds.

Unlike K&N's automotive replacement air filters, K&N heavy duty air filters like 38-2011S and 38-2025S do not require oil, so they can be washed almost anywhere. Cleaning is a simple matter of spraying on Heavy Duty air filter cleaner, allowing it to set for a short time, rinsing the filter then allowing it to dry. An air compressor can be used on a lower setting to speed up the drying process. Once the filter has been dried simply re-install it and you will be back on the road in less time than it takes to wash down the rest of the truck.

Parts 38-2011S and 38-2025S have a radial seal, matching the OEM replacements they cross reference to below, as well as, a metal support grate on the outer edge, for extra strength. Heavy duty air filters 38-2011S and 38-2025S fit in place of the factory OEM elements and include basic installation instructions. K&N relies on the utmost quality when designing and manufacturing their heavy duty diesel products and K&N stands behind them with a 300,000 Mile Limited Warranty.

The BMW M135i's unique body styling has been specially designed to handle the impressive power delivered by its powerful engine. The M135i is in fact the most powerful derivative of the second-generation 1-series.
