While simple in principle, the S-Flo for the 2.7l twin turbo produces quite tangible increases in engine power and smoothness. The resulting improvements are from a combination of air filter design and the precise mandrel bent transition tube. The ITG Maxogen cone filter used in the kit provides nearly 30% more intake surface area over a drop in panel filter and has a unique venturi shaped outlet that reduces air turbulence.
Our scan tool measurements recorded increases of 25 grams-per-second of air through the mass air flow sensor (MAF) at various points of the rpm range, with a dramatically smoother flow curve. Dyno tests repeatedly show a 8-9hp power gain to the wheels!
The S-Flo installs completely within the stock airbox and therefore has a stock appearance and sound. Very stealth.
