You could have answered your own question eons ago by doing a little legwork yourself... <ahem - search Nazi>

1. Contradiction - MAF Adapter + K&N drop-in is not an option. The MAF adapter is needed when attaching an open air filter to the MAF. Hence the name. Drop-in is just that. Drop... In...

SVT K&N drop-in = ~2FWHP
Open air K&N conical = ~6FWHP/2FWTQ

2. I'm willing to bet nearly all the claims you have read are bull. I can guarantee it if you mean any from the manufacturer or seller!
