Will a cold air intake make a noticible difference in power for my 94 Tracker? I've got an automatic tranny and the power is nothing to write home about. I know about K&N filters but does anybody know of a more "cost effective" brand that might offer similar results. If you saw my other post regarding suspension lifts then you know that I'm on a tight budget!
most cold air kits are useless (sorry)
unless...
it is fed from a HIGH pressure zone.
keep in mind , cold is more more dense and flows less easy and hot air flows more easy
thru a given duct. so any gains in oxygen are hard to get with the flow decreases....
so
do it right , make a pipe that goes from the stock air cleaner to the vent Cowl.
cut a round hole in the cowl (mine has a screwed on plate) and fit a hose to this point.
now when you move fast, you have "poor mans turbo" called RAM air.
dirt cheap and easy power.
The biggest restrictions on modern cars are not the Air cleaner.
it is the throttle plate and then the valves, followed but the CATCON.
get an 16v engine as that has way more power.
BTW, this can not be dyno'd as you must be moving the read the HP gain.
most cold air solutions , reduce power,
many have been tested by very careful people. (the scientific method)
if you want the whole story check Jeff Hartmens books. (sold everywhere)
hope I saved you some hard earned cash.
cheers.
PS. question 2,
will i feel it,
sure the booty dyno never lies. LOL.
no. the power only happens going REAL fast. way too late to notice. IMHO.

The increase in power is proportional to the reduction in air temperature. However the temperature must be calculated from absolute zero (-273C/-460F). I've measured the intake temperature on my 8V at around 50C at idle, I don't have any rolling measurements. If you can achieve it then a 25C/77F reduction in intake temperature should therefore gain you approx (25/300)*100% = 8.3% more power. This will be reduced by the effect described by JTGH so maybe 5% or 4bhp.
How well serviced is your vehicle? I've seen much bigger increases from a change of oil and a fresh set of spark plugs.
I did some dyno testing on air filters on a bike a good few years ago. The K&N gave the best performance, some of the cheaper brands were quite shocking. Be aware that a K&N will not give the same filtering as an OE filter and engine life WILL be reduced.

This sounds like a great idea, you woulndt have a pic or two would you?

go to miata forum ,log in and read the stick on, cold forced air.
they made a nice kit and tested it on the track and it works.
but you have to go fast.
keep in mind this.
cold air is thicker than hot air.
so cold air is harder for the NA motor to suck in.
This takes very very carefull engineering to make this work and not suck in dirt bugs and water. the engine bay is filty, ever clean one every year like me. see all that sand dust and crap, why suck all that in every day, WHY?
never seen one yet (generic junk)
If you really want to go fast , remove the Throttle body butterfly plate, go ahead. Hah ! Where are those cojones?
[ there is a car manufacture, that did that, but do research on how the BMW series 7 , works for real ] Google it.
things pro's leaned about so called CAI.
1: metal pips are no goodl they ubsorb heat
2: plastic works better. especially white. ( stops the hot bay from heating air tube)
3: long pipes give more low end torque. oops, so much for short CAI.
4: messing with the front pipe sections near MAF causes MAF to got nuts. ( MAF likes laminar air flow , hates ! the turbulent)
5: butt dynos are useless.
6: loud induction moan , dont make more power.
it is possibe with custom ecu and whole exh and induction to tune the whole thing
so the VE goes over 100% at one tight RPM band. (racing)
VE over 100% is turbo like.
VE over 100% exceeds the displacement of the motor.
read up on that and exhaust scavanging if really interested in how the pump works.
very very interesting, read Jeff Hartmans books. all of them.
ve = volumetric efficiency ,something that Turbos, overcome.
