BSR’s sport air filters increase the engine power with 3-4Hp. The air filter has a lower air resistance than a standard filter. Generally the engine runs up faster and responds faster than with a standard filter. When the car is tuned it’s sometimes necessary to change to a sport air filter because the engine requires more air at full charge.
The filter material consists of a unique cotton fabric giving the best combination of low air resistance, efficient filtration and long durability. On both sides of the pleated cotton fabric there is a steel net to strengthen the filter and to prevent that the filter is sucked into the engine. The filter is sealed by soft edges made of polur ethane. The filters are washable and if you maintain them properly they will last the entire life of the car.
