INFINITY DESIGN carbon intake F8X M2 M3 M4 S55

The system matches the factory intake system for inlet temperatures.  In addition the system changes the air flow characteristics for a smoother delivery and allows more air to enter the turbos more easily.  This fully developed and intelligently designed intake system is not just something that looks good in the engine bay but does an impeccible job as an air smoothing device, increasing air available, increasing air speed into the turbo's, allowing the turbo's to spool faster, filters for longer more efficiently, keeps intake air temperatures low and making a sophisticated race car like intake noise under load.  Most important of all, it is the way the engine becomes more alive, responsive and enjoyable to use not just under full load but also normal every day driving.

Average +10-15 WHP / + 10 lb.ft  
Average Peak Gains - 15WHP @ 6700rpm12-15WHP 5800-7500rpm.  The results are as expected for a large volume system with ​large velocity stack shaped inlet tubes.  The OEM system flows enough up to 4000rpm up to which there are small gains in power.  After 4000rpm, power gradually increases to the rpm limiter with 12-16 flywheel HP from 5800-7500rpm.The Maximum Delta gains from the average stock run vs the highest run with the carbon intakes is also displayed on the third graph.  While this is a real result we do not quote this HP gain as part or our marketing. This gain is possible however.  The gains are realistic as the power increases from 3000rpm onwards with no gain below this.  The graphs are not a phase shift which is typical of dyno tests where the correction factor has been changed to show larger than actual gains for marketing purposes.
