Expected gains cold air intake/throttle spacer

Just wondering how much hp/tq I can expect to gain from a cold air intake and 1" throttle body spacer.

Thanks

Nothing that you will notice when driving.

If you don't have time to do it right the first time, how do you have time to do it over.

I can't tell you from experience because I don't have either one but I've heard that the cold air intake has a decent increase but the TB spacer does nothing.

all depends on what your definition of CAI is. even if you are talking about a true CAI i would doubt the price is really worth the gains.

I'll see if I can find it but I think I remember a thread debating how the K&N Intake actually does what it claims.

CAI's were brought to the market via use from racing . At WOT , such as on a dyno , yes , there should be an increase in HP over the stock box . If your planning on racing your jeep . If not , all your gonna get is worse mpg's due to listening to the cool sound othe intake makes IMO . I doubt your gonna feel any differences .

TB spacers are a waste of money on anything other than TBI or carberated engines . MPI systems have injecters right above the combustion chambers , they would serve no pupose .

Buy a good Amsoil or K&N drop in , save your $$$

Thanks for the responses. These two items are now off the future upgrades list.

If you are really looking for gains...then you better have deep pockets my friend. Best way...and cheapest is to stroke it...the engine you perves...I don't wanna see another quote in someones sig.

for a full CAI it has given us slightly more than what changing a dirty air filter does. we have seen about 1/2 MPG improvement. the performance gains are there. small but there. it shifts differently or not at all on inclines depending on slope and speed.

acceleration is better. many will talk about WOT and top HP gains. what they fail to realize is that MORE air is getting through the engine at all other speeds. the difference is modest but noticeable. is it worth the cash? depends how and how much you drive...

could save you 20 gallons of fuel each year. do the math, seems worth it and you can clean it earlier thereby keeping your MPG and performance up.
