From what I have heard, the throttle body/CAI allow more air into the engine, which normally would not be very helpful because the ECM is not designed for that additional airflow. The chip reprograms the ECM to accommodate the increased airflow. I have yet to see someone who has actually bought one of these kits and hasn't noticed any improved, and most people note significant improvement.
They advertise 20% increased HP, which is a very optimistic number if you ask me, considering that is near 40 HP, but from what I have read, people have noticed 10%+, which is still around 20 HP. I'm not sure why people assume that we want more HP for "1/4 mile times"; i just want more HP to turn my 35s, to reduce the number of downshifts, and to increase fuel efficiency.
20%? You won't get 20% without spending at least 3 grand unless you go nitrous.
How do you "notice" 10%. Butt dynos are not that accurate and dyno sheets are notoriously manipulated.
I built my own. Would i buy one... Nah. And yeah 10% is a big gain, doubtful you would see the extra 20hp. Not trying to stray here but the whole percentage thing is really kind of a misleading thing, for instance... My boss just had a 468 big block chevy built for the shop truck ( fully custom hand fabbed 68 chev) all roller cam, AFR heads, scat crank yada yada. Engine builder says easy 625hp. We do several dyno pulls with it with a dual plane intake and a vacuum secondary( choke wheez) carb. Best number... 540hp. Nothing to sneeze at grant you. My input was go for the single plane intake and a mechanical secondary. Dyno guy says, no way those are a pita and will only net 10-20%. So i split the difference. Were all smart here, do the math. Sorry for the rant. Do what u want man. Its yer$$$ and yer jeep. Even if you only see 3hp and 1mpg it will pay for itself in a a few tanks of fuel.
Yes guys.. guess I am looking for a glimmer of hope to the CAI yes I know it does nothing but Im 50 years old my jeep is my toy and know what Im probably going to just buy one anyway.. maybe what I should ask is this..
WILL IT HARM anything or what are the DOWNS to having one.. I dont mind my jeep staying to same after the change but will I loose anything..
Boys with their Toys...
Should see my 65 Comet Cyclone..
Technically, they should let more dust in, especially when not using a pre-filter.
I bought k&n for my mustang and jeep, threw them both out after 2 weeks of dealing with MAF sensor problems. I didn't even oil them, since they come pre-oiled. I bought the AEM dry filter and have run it for 12 years now (140k miles), no problems, and no dust in the intake.
Again, no performance gains, but I am not seeing any drawbacks either. But there will be MANY who disagree with me.
