when I ordered my intake from K&N it came with a dyno chart of a before and after of a 99 mustang gt and it said it gained 10HP at the wheels... I personally think this is a load of crap but if you guys know something I dont can you let me know?

 

No theyre full of crap...... You will gain maybed 2-3....

 

heh.. I thought so.. how can they get away with that, isn't there a law somewhere like false advertisement or something?

 

In all honesty I am sure they made 10 HP ONCE, but typically they don't make that kind of HP.

 

Or they made 10 hp, having all the other mods that compliment the intake

 

it's not false they test in perfect conditions

 

Pretty much they can just put a bunch of other mods to help flow, exhaust etc. and put the crappiest filter they can find; then dyno them.

 

Put them on my 99gt and my tahoe and I notice a better thottle responce maybe alittle more hp. It also sounds great.

 

Good Link. Heres a link to some good minor mods info. done by MM&FF.
