ISO 5011 Certification
Test Stand to compare airflow
of new intake kits to the
stock setup.

All Halltech Filters are  ISO 5011 Certified.  The ISO (International Organization for Standardization) establishes and specifies uniform test procedures, conditions, equipment and a performance report to permit direct laboratory performance comparison of air filters and induction systems.  The performance characteristics of greatest interest are airflow restriction (differential pressure), dust collection efficiency and dust capacity. The ISO 5011 Standard is important to those that want to keep their Corvette engine up to OEM standards of 99.4% efficiency for dust and dirt removal.

The end result is simple: Increased horsepower by reducing the restriction of the air filter and/or intake kit while still protecting the engine. Recently Katech Engine Development dyno tested our Standard, Race, and ISO 5011 Filter and found less than 1 HP difference on a 620 HP engine, which is considered by Katech the margin of error between pulls.  Katech did not require this certification for their endorsement, but since they are a Tier 1 Vendor for GM, Halltech made the decision to use only ISO 5011 Certified Filters for all Killer Bee Ambient Air Induction Systems.

How can the Killer Bee Filter produce 12 HP more than stock and still have 99.4% filter efficiency?  One word:  Surface Area.  Our ISO 5011 Killer Bee Filter is so large that it dwarfs even the K&N Air Charger Z06 filter, and has 100% more surface area than the PowerCore filter it replaces.  



Testing to these high standards enables us to accurately measure our products against not only OEM [Original Equipment Manufacturer] equipment, but also to the competition, allowing us to establish the air filter performance benchmark, which we are determined to do.

ISO is a worldwide federation of national standards bodies. The work of preparing International Standards is normally carried out through ISO technical committees. The specific individual International Standard utilized by S&B and automotive manufacturers establishes and specifies uniform test procedures, conditions, equipment, and a performance report to permit the direct laboratory performance comparison of air cleaners, in this case, those used on internal combustion engines and compressors used in automotive and industrial applications.

"This standard is important  because it is the worldwide accepted yardstick for measuring the performance of filters and intake kits utilized by all of the automakers."

Halltech Filters can be tested at airflows up to 1,000 cfm with its ISO 5011 Test Stand.


The ISO 5011 Test Standard demands rigorous attention to detail which includes heating the blankets prior to and after testing to remove any moisture.


The ISO 5011 Test Stand is a state-of-the-art machine utilizing computer controls to virtually eliminate any margin for error.
