do you think i should mod the housing or just keep everything the same?
I think I need to explain my comment a little better. Doug and I had a good conversation over the phone last night and it dawned on me I didn't explain my comment very well.
I’m a fan of the factory air filter because in numerous dyno tests (that I have done) it has out performed on the top end. The Airaid while loosing top end power does offer more air flow down low. This causes the EGT’s to be reduced (don’t know how much), and increases the mpg of the truck on the freeway (about .5 mpg in my testing). So, it is a good alternative to the factory intake.
For me, if I can have the top end power in a factory package, I’m going to. That’s because I believe that Ford has the engine’s best interest in mind. Ford spent a lot of money, time and research in developing the intake. They test it in numerous environments and a lot of different circumstances that I don’t believe most aftermarket companies take into account. So, in my book, if I can get the same power out of a factory component, then I’m going to keep it.
Is the Airaid a good filter, yes. Increased mpg and reduced EGT’s in the rpm range the most people drive in most of the time. But when I hit the track, I’m looking for power, not fuel economy.
As far as an aFe, I have never had the opportunity to do back to back testing. So, I don’t know.
