Sprint Filter Off-Road Unveiling of T12 and T14 Filtering Media

Sprint Filter Air Filter


T12 and T14 Brand-New Filtering Media

Sprint Filter, the leading name in high-performance air filtration solutions, is thrilled to announce the launch of two revolutionary air filter media, T12 and T14, designed specifically for the Off-Road world.

These new products, built from two different unique non-woven fabrics, emerge as the result of years of rigorous testing and development in some of the most challenging terrains globally, in collaboration with leading manufacturers. The data highlights a level of filtration unattainable by the current standard used in Off-Road and pressure drop values significantly lower than the competitors.

In addition to years of field testing, both T12 and T14 air filters have undergone ISO 5011:2020 certified tests in an accredited laboratory. Data suggest unattainable filtration and minimal pressure drop rates


Sprint Filter has always stood at the forefront of innovation. Our brand-new T12 and T14 air filters are dry filters, requiring no oil additives and are virtually maintenance-free. All it takes is a simple compressed air blast to have them cleaned and ready for reuse in seconds. This means less downtime and more time in action for off-road enthusiasts.

The brand-new T12 and T14 filters have been rigorously tested for several years in diverse and challenging environments, ranging from desert terrains to muddy trails. This extensive testing, conducted in partnership with renowned vehicle manufacturers, ensures that Sprint Filter’s latest products meet and exceed the most stringent performance and quality benchmarks.


With the introduction of the T12 and T14 air filters, Sprint Filter establishes itself as the most comprehensive and globally recognized performance air filter producer in the market. These new products cover a segment traditionally dominated by oiled foam filters, expanding Sprint Filter’s reach to meet a wider array of consumer needs.

The sprint filter air filter cleaning procedure is extremely easy and quick: just use an air jet in the opposite direction of the suction to remove most of the debris collected. DO NOT OIL!

Off-road motorcycles are normally fitted with paper filters, while the usual solution for sports filters was foam. With its adoption of these new filtering media, sprint filter has taken a huge leap forward, making all previous systems obsolete

Sprint Filter Sets New Benchmarks with T12 and T14 Air Filters

The prestigious Italian weekly magazine Moto Sprint dedicated three pages to the technological innovation that Sprint Filter unveiled at EICMA for Cross, Enduro, and Adventure motorcycles. 

Sprint Filter, a renowned name in high-performance air filtration, has advanced further with its T12 and T14 models, specifically designed for Racing Off Road single-cylinder and Adventure motorcycles, showcasing technological progress.

These new products are crafted using non-woven polyester fabric technologies; they are dry filters, not requiring additives/ oil for optimal functioning, thus maintenance-free. A blast of compressed air is all that’s needed for their peak efficiency.

THE T12 MODEL boasts increased filtration capacity and is also water resistant (eliminating the need for the socks required in traditional systems to prevent water infiltration into the engine); it’s ideal for extreme off-roading, Rallies, and generally recommended for those seeking maximum engine protection. The T14 model offers greater permeability than the T12 but still ensures significantly higher protection compared to traditional oil-soaked sponge filters.

For several years, Sprint Filter has field-developed these products alongside various Motorcycle Manufacturers. Notably, Aprilia fitted the T12 on their Tuareg 660 for the Italian Motorally and TransAnatolia Rally. Less known, but equally intriguing, was the collaboration with Team MTR KTM, fielding Lukas Höllbacher in the Supermoto S1 World Championship. Sprint Filter also developed products with other Manufacturers, but some of these agreements will only be officially announced in 2024.

BESIDES field trials, Sprint Filter conducted lab tests and the ISO 5011:2020 certified test, demonstrating unmatched filtration levels by current Off-Road products, and significantly lower pressure drops than components using older technologies. This translates to better, consistent performance over many kilometers and greater engine protection.

Delving deeper into the data, the ISO 5011:2020 test, often referred to as the “Coarse Dust Test,” is a standardized procedure developed to assess the performance of air cleaners and filtering media, particularly in internal combustion engines and compressors. This test is crucial for sectors like automotive and motorcycle, where air filtration system efficacy and longevity are key.

In this test, Sprint Filter benchmarked against oil-soaked sponge air filters, the prevalent technology in the after-market, also used by some Manufacturers in standard motorcycles.

The test revealed that to ensure good engine breathing, this filtering system requires frequent maintenance. Additionally, even with a perfectly efficient system, over 50% of particles enter the engine, with a lower air flow than the Sprint Filter T12 and T14, which also retain a greater amount of particles.

DELVING further into the details and analyzing the test results, it should be noted that for conducting the tests, a KTM 1290 Super Duke airbox was used, modifying the duct to obtain reliable data; with this layout, the air flow is perpendicular to the filter, and the duct is centered inside the airbox.

THE FIRST test is conducted without the filter element; at 900 Nm 3 /hr, it generates a pressure drop of 20 mbar. To clarify, a filter with high permeability should, at 900 Nm 3 /hr, generate a pressure drop as close as possible to 20 mbar. The oil-soaked sponge filter, at 900 Nm 3 /hr, generates a pressure drop of 59.6 mbar, which drops to 47.6 mbar for the Sprint Filter T12 and only 36.7 mbar for the Sprint Filter T14.

  • Left Graph – showing greater permeability of Sprint Filter products without contaminants.
  • Right Graph – the Dust Loading test, proving T12 and T14 filters block large amounts of contaminants.

The second part of the test checks the amount of contaminant the filter retains. On the oil-soaked sponge filter, to generate a significant pressure drop, 70 grams of contaminant were poured (a considerably high amount) in 120 minutes. On the Sprint Filter T12, less than 20 grams of contaminant were enough to generate similar pressure drops; for the Sprint Filter T14, 40 grams of contaminant were needed.

This means that the oil-soaked sponge filter, in maximum efficiency conditions (thus without contaminant), limits the engine’s breathing compared to Sprint Filter components. In extreme use conditions, off-road, the oil-soaked sponge filter ensures good breathing but at the cost of higher engine wear, caused by the passage of a large amount of contaminant, compared to both the Sprint Filter T12 and T14.

Following this reasoning, with data in hand, it’s clear that the technology developed by Sprint Filter ensures better engine breathing and greater protection. One might think that, in extreme usage conditions, when Sprint Filter products have blocked most of the contaminant, engine breathing might be penalized. In reality, during the ISO 5011:2020 test, the throttle is never closed.

In normal usage conditions, when the rider closes the throttle, part of the contaminant moves from the filter element to the walls of the airbox, ensuring good engine breathing even after many hours of use on sandy terrains.
