homade CAI??????

[93vertboi]

bought a K&N drop in filter and took off the inlet piping on the airbox is sounds like a cold air all thorty and sounds cool...... is this legit at making a good air supply to a bone stock KA?

[churro]

You are just going to suck in a lot of hot air. A better solution is to follow that short skinny pipe down into the bumper/fender area and cut off the box so you just have a pipe. It may not sound as nice but at least the air will be colder.

[93vertboi]

that is true about the hot air thing but look at any CAI made today where is the air filter located same place as the stock location with no "cold air" there just engine heat air and air from driving? just a thought not sure though

[somedude]

youre right. most kits dont relocate the filter. just because there is no room to do so. the real gain comes from the redesigned and smoothed out inlet pipe. i personally dont like k&n. all it does is let more dirt in. dont believe me? you can practically see through them!

I wish I still have the stock air box. In fact I'm going to buy one in junk yard later.It'll be better to make a bigger inlet on stock box than those so called 'Cold' air intakes.

thanks for all ur replies and comments next question up for grabbs........ ebay cat-back for 200 bucks or buddy club spec 2 for 330?

[dickie]

intake on an otherwise stock ka won't do anything but increase your sound level. maybe gain 1 whp at best.

[93vertboi]

not trying to be smart but i know how HP works and how much is lost in drivetrains of vechiles so i knew none if any would go to the wheels since all i did was just let more air in and hot air at that.... appriceate all comments though.

[Soravia]

Better radiator and cooler thermostat would help cool your engine bay better.Also, even if you push in cold air, your intake manifold will still be hot because of the coolent running by it.

[neverlift]

now this is the end here. In my case it could only get better with a cone filter INSIDE the air box.

I have an aftermarket front bumper, with big cutout on each side(left/right) I took a piece of aem pipe my friend had and cut it to make a short ram(pas. side where battery goes). Then I cut stock air box lower half open ,making a mouth. again in my case this is the best solution to hot underhood air, the battery tray has long since rusted out so a nice hole for the airbox was already there, it sits perfectly down in between the rad support and fuse box.

total cost of the mod was nothing. The airhog filter was free(came wih the swap) ,the pipe was free( can be in your case too maybe(cut your stock pipe)),air box was free came with the swap.no fancy dyno but the car pulled to 63 in second last night after the mod. and has not done so before.(with many tries). I dont think I gained too many hp with my mostly stock car(int/ext/fpr/walbro/msdcoil) but it really helped the death of power around 5k. RESULTS WILL VARY!

the coolant lines to the t/b can be removed, just heat wrap the rad hose to keep any direct heat contact to the intake pipe for the coolest charge. again like said by many intake on ka is pointless. BOOST lol that my plan.

Also, even if you push in cold air, your intake manifold will still be hot because of the coolent running by it.

And thats a good point why? Let me guess. You think that just because someone has an accuall cold air intaki (grabbin air from outside the engine bay) that it will have no effect on power cause the manifold will just heat the incoming air up to the same temp? PSHHHH! palease.......................... air heats up at a constant rate. I.E. if you suck in air thats already 100*F and your manifold heats it up to 150*F. If you suck in air thats 70*F it wont be 150*F when it enters the cumbustion chamber. It will be 120*F. Therefor, the colder the air going through the inake the colder the air will be in the combustion chamber. And we all know colder air is more dense. Dense air has more molecules in it. More molecules means more power. If you can add just a little bit more fuel in with all that denser air, even more power.

O.P. Spectre has a line of intake stuff you can use. They have a few styles of 90* bends, 60* bends, 45* bends, 20* bends, and straights. you can fab up just about anything with those options. Good luck and keep it ouside the engine bay. Or atleast use a heat sheild.

That makes no sense. I could wind my 2nd gear out to 70 if my engine would stay together until 10,000rpms

well it was ONLY to6850(stock tuned auto ecu)which after trying to run it up 60 in second before yielded nothing but 57ish.... how that doesnt make sense IDK if I got to 63 at 6850 then you should only need to go to about 7500.

Doesn't the S-13 (more in S-14) already have air boxes that takes in air from outside the engine bay? They're not all exposed but they do take in air outside of the engine bay. Plus that design doesn't throw mud and crap at the filter. The inlets could be a little larger on stock box though.

[churro]

The S13 inlet pipe has two sources. One goes behind the pop-up light and the other goes down in between the bumper and fender liner. I agree those inlets should be bigger.

[Soravia]

S-14 has three that goes into thwo and one even has inlet under the bumper.I just made S-13 box with S-14 inlet mix which take direct air in true RAM style.Pics coming later, I need to get filter, can't afford $50 Air-hog yet though, just OEM.

PicsI used ample amount of duct-tape.

The air passes through the grills on the bumper and directly into the pickup pipe. I always loved those things.

You can see the rear pipe taped so that air won't pass through. It's also taped inside as well.

the stock airbox inlet work pretty well, ive been thinking of somehow drilling them to allow more air flow, and using the pipes to connect them or put them very close to the cone
