Further informations:
Sprint Filter is a company dedicated to the production of high-quality sports air filters for high-performance car. Founded in 1952, the company is well known in the automotive and motorbike industry for its focus on the highest quality and excellence in its products.

Sprint Filter uses only the highest quality materials and state-of-the-art technology in the design and production of its filters. Each filter is designed to maximise the amount of air that enters the engine and improve the car's output and performance. Thanks to their greater filtering surface area and ability to trap the finest, most engine-damaging particles, Sprint Filter sports air filters provide greater engine protection against wear and contamination, increasing the life and reliability of the car.

The polyurethane foam fabric of the P08 material has a high-density three-dimensional structure, which enables it to capture particles even smaller than 50 microns, preventing them from reaching the engine. In addition, P08 has a higher filtration capacity than traditional materials due to its high air contact surface area. P08 technology offers many advantages, including the extreme strength and durability of the material. Sprint Filter sports air filters with P08 technology provide superior performance compared to standard filters, improving the performance of the car and increasing the power and efficiency of the engine. In addition, Sprint Filters with P08 technology are designed to be washed and reused several times, reducing costs and the environmental impact of waste.

The P08F1-85 consists of a layer of open-cell polyurethane foam, covered by a stainless steel grid, which increases its stability and resistance. Compared to the P08 technology, the P08F1-85 offers a higher filtration capacity due to an even higher pore density and an additional filtration layer. This allows even smaller, engine-damaging particles to be retained, ensuring greater protection and improved engine performance. In addition, P08F1-85 is characterised by increased resistance to high temperatures and vibrations, ensuring greater durability and stability over time.

The P037 (WP) variant, on the other hand, is a waterproof, ultra-fine air filter specifically developed for use in harsh conditions such as dirt, water and dust. The P037 is capable of filtering debris down to 37 microns, while guaranteeing an air flow equivalent to that of our class-leading P08 road/race air filter. Special filter versions are not available for all car models and are only recommended for those who want to maximise the performance of their engine and have made modifications to the mechanical and electrical parts of the car. They are not suitable for classic road use. If you are looking for other Sprintfilter products or are in doubt about the ideal filter for your car, please do not hesitate to contact us for assistance.
