Five generations. One year.
PRESION exists because oil mist in the intake is a real failure mode, not a cosmetic one. It started as a PLA prototype zip-tied to a 4.6 F150 and went through five full generations of baffling geometry, material testing, and real-world validation before it shipped, and it has now run 12 months on a 300k-mile engine in a prerunner. Rev 5 ships today; Rev 6 is in road testing and replaces Rev 5 at the same price. Every product gets proven on a real vehicle before it gets sold. Not before.
Designed and tested in Texas by people who actually work on performance vehicles — not a marketing department.
