is low end torque lost with cold air intakes?

Yes - it's possible. Not guaranteed, but possible ....
I had a K&N cold air intake on my truck and noticed that I could not spin the tires from a dead stop. I ended up taking it off and putting the stock air box back on with an Amsoil drop in filter and now I can smoke the tires from a dead stop. So in my case, YES, I did loose low end torque. I even made a sealed top for mine and was able to keep the air inside the K&N air box about 10-20 degrees warmer that the outside temp. which isn't bad, considering how hot the engine is. Needless to say, now the K&N is sitting up in the attic now!

Exactly where it belongs. CAI, headers, etc. Are mostly for looks. Honestly? They really don't do you a whole lot of good as far as performance is concerned.
i got a little on the top end

but lost down low

i gotta let it go pretty good just to get a decent start off the line against somebody



i just HATE the look of the stupid stock airbox, hence why I keep what I got on there now
im not taking mine off. too expensive. and maybe some better mpg but its been on so long i cant tell and never really checked. wouldnt do it again though.

Check your fuel trims, if they're not near zero (probably they aren't) you'll loose throttle response and power.

im not too sure but if you loose low end with slappng on CAIs then u can just slap on a SC to get it back and add more power..just a common snse suggestion.:shrug:
yep that's what happens with all CAIs and exhausts, headers will pick it back up.
i forgot about this for a while but i am now thinking about taking my CAI off since i rarely/never rev the engine high enough to benefit from it and would use the low end power (assuming there would be a gain?) more often

any opinions - possibly new information

thanks

Not normally, those things you mentioned are designed primarily for top end flow, so generally the will gain on top where flow matters.

Its not making a huge differenge anyway, you can sell it and use the money for gas..
