You're talking about removing your snorkel and replacing it with ththe ST intake scoop? You're not referring to the FRPP intake kit are you?

It is safe either way, some people have seen the engine bog more when it is hot and the lid is off, so it is personal preference.

TboneZX3 You're better off with the top on, to keep out excess engine heat and lower intake temperatures, IMO.

You have two options for the K&N drop-in:

K&N E-2993

or...

K&N E-9289

I recommend the E-9289. With the plug out, you will have better flow with a louder, deeper intake tone without sounding obnoxious. With the plug in, it is quieter and works just like the E-2993 or factory filter. I run it with the resonator/silencer installed though.

thanks
all input will help.
The intake resonator is just for sound dampening, it should not be causing performance issues. Unless that part of the engine bay was really hot, which I don't see why it would be, it shouldn't be changing temps much.

Sonic_HedgeHog AEM is the only true CAI since it moves the filter out of the engine compartment... It also carries a CARB legal sticker now

I'm running the K&N... _RED_ and many others are running the Steeda. FocusBoy58 is running the AEM.

ripto Gotcha, thanks guys. Do the legit CAI's also move the filter away from the engine more at all?

And the question is... what do you think the difference between the two are... 2-3 hp?
