He gained 3.94 HP ($18 per HP) by adding a BMC air filter. Then he removed the airbox and added an EVO air intake and gained (not additional) 6.27 HP. ($60 per HP). It seems as though the BMC air filter is the better bang for your buck, but for these cars every HP you can squeeze out is better, for an additional 2.33 HP over the BMC, which would you do?

"With Fabspeed Performance Package" (FPP) will the gain of 3.94 come without the Fabspeed Performance Package? What does the FPP include? Chipped, headers, free flowing exhaust.

you will never get 3.94 whp with only the filter. You will need the the exhaust package to get that. If you observe how they did the dyno they installed the exhaust package first and then the filter. You won't achieve that by installing just the filter alone.

The Fabspeed Performance Package is $4680.00! It gets you 22 hp.
