K&N cone filter part # for Aspire

[ericsmith32]

If anybody wants to convert their Aspire to a K&N cone filter the part number is RC-9420 (although there may be some others that are similiar). It has a hole already there for the IAT I don't know what it's original purpose was. All you have to do is knock out the retaining nut out of the airbox and use it to tighten it up. It's a tight fit so with big hands it might be a bear. It wasn't my original purpose to have a k&n with predrilled hole - the website didn't say anything about it. After that you need a 3/16 double side vacuum connection and drill a 3/16 hole stick it in and get a longer 3/16 hose for the egr crapola and your done - well you have to make a bracket but's that's expected. I took out the MAF screen while I was at it but I don't recommend it if your the faint of heart.

air filter

in aspire, the restriction is not the filter...it is the silencer before air filter...
it is freebies to remove it

the fastest aspire auto ( for now ) in the world

I did that first but this is so much better. It has no restrictions now and really it didn't take any longer to do the cone versus modifying the airbox. The longest part was taking out the screen seeing that all the darn wire snippers magically disappeared in this house. I can tell ya this thing screams now. I can actually go up hills against the wind without downshifting.. amazing just amazing. :lol:

Eric,

Do you have any pics of the conversion? Doesn't sound too hard but would like a look at it before I try it.

[ericsmith32]

I guess you want pics of the airfilter..

Welcome to hot air city and poor filteration town.

[ericsmith32]

Show me an analysis to back that statement... i've seen a couple which most likely can point to user error.. it's kinda like everyone dreading fram oil filters when as far as I've heard only a couple has inploded.. if that. That setup doesn't draw anymore hot air than the stock setup.. I do have another setup now that pulls air from the fender but it's still in the same area.

oem vs k~n

oem air filter take fresh air in the fender.... p-flow (k&n) like the one see in photo take air from engine compartment...hot air.
i dont remember wich companie made some testing on dyno and a poor design air filter ( under the hood air intake ) make 10 to 30 % less power than a well designed system who take fresh air.

on my aspire ( bp turbo intercooled ) i take hot air :x
i have no place to take fresh air...intercooler piping take all place...i must live with that but if i can take cold air i thik i can push the engine higher ( hp)

this is my little opinion

We've all seen a LOT of cars (of other makes) with the same basic engine compartment setup, most sold with that specific design.

While I'm sure that this is true (in theory if nothing else), it seems that it would still be better than the stock system, wouldn't it?

While some of us can do basic repairs on their cars, many of us (myself included) don't have the knowledge or skill to fabricate extensive intake systems from scratch, nor want to alter the primary structure of our vehicles to do so. While this may not be ideal, if it's a marked improvement over stock it seems still worth doing?

fresh air

why all auto maker take air in fender or in front of rad ?
colder the air is entering the engine the more powerful it is.
nothing else :shock:

Here's my setup during the summer:





I take it off during the winter to try to help warm my car up.

I think this year I might redo it with PVC pipe

According to fluid dynamics that would not flow very well because of all the bends in that dryer duct, and the fact that the walls are not smooth, slows the air down also. So does temperature of the air affect the car more than poor delivery of the air? And how hot is this hot air that eric's filter is sucking in?

[ericsmith32]

If I feel the 3" exhaust pipe on my current intake setup it was cold even on the days it was into the 80's. It got a little warmer closer to the tb but not much. It may not be a good test but I have a laser thermo and when it gets warmer i'll monitor the intake temps and see how it correlates to the outside temp.

I love my intake, makes it feel like its a different car. i drove my car for months with only exhaust and it was ok, but when i made my intake it makes the car that much more better to drive. The ass dyno says more power to.

I took the pics before I recut it.

It doesn't have to "ram" the air in there. Just direct non-hot air to the airbox.

I'm not sure what the underhood temps are on our cars. I know on my crown vic places directly above the heads can reach 160 or 170 or something.
