HPX

We have worked eight years developing the perfect flow curve for the HPX mass airflow sensor. This sensor can be used in any size housing from 2" to over 5" on vehicles making 200 horsepower to over 1700, without any loss in useable resolution. This means a sock idle in a 1500 horsepower monster with a 5" maf housing or a lightly modified mustang with a 75mm maf and headers. We are the ONLY mass airflow manufacturer with the flow capability to actually develop maf calibrations for use over 400 horsepower. Our primary flow station is the only one of its type in the country. It's capable of over 8000 KG/HR (2000HP) AND it's N.I.S.T. certified to be accurate to 0.19%. Our competition can only flow to roughly 2000 KG/HR (500HP) and has no type of accuracy certification. What does all of this mean? It means that every sensor we build is perfectly calibrated and is better than O.E.M. The HPX is the one maf that will evolve with your car. This is simply the last maf you will ever buy! Use the HPX maf in your own custom intake or use it with one of our high flow maf housings for BIG horsepower gains.

The HPX is based on the (cartridge) style mass airflow sensor. This sensor is great for Blow-through or Draw-through. Its special design is great for reducing signal noise and reversion. The tonsil style sensor used by others is not well suited for the performance vehicle. It was designed in the 90's and is very outdated for today's complex automotive systems and performance parts. Use of the HPX maf system requires computer tuning.
