I know I know. I am SO uncool. I just bought the drop-in instead of a cone intake. :cool: Sold a few things on Ebay I would have just thrown away. So it was free basically. ($37).

I REALLY did not expect ANY improvement. I was wrong. Supposed to only add a few HP (which you shouldn't even feel, right?) but I swear it feels a bit peppier. Really laid on it today and I swear my boost gauge went farther then I've ever seen it. Maybe just a hair or two farther into the red....but farther none the less. It feels so much better. I can even feel the car breathing better. The idle smoothed out a tiny bit.
Could be because of the KN and the fact that my old one was pretty dirty, but whatever. I'm happy.

Certainly good bang for your buck.

Hey, I only have the drop in too, does that mean I am also uncool!? :confused:

Its a great easy mod, even if you only do it to be able to wash and reuse the filter!

Thought I was the only one who noticed!!

I put mine in today and also swapped out the old bosch plugs for some NGk BCPR6ES-11's and WOW, to me it seems to run better compared to the old Mann filter I replaced. The car seems to idle smoother, sound a WHOOOOOOOLE lot deeper/nicer (I've got the sport exhaust)...wow, I'm so stoked that a little job like that could do such a difference. :) Tomorrow, I plan on doing the BPV to BOV and also the 3" intake DIY's. Hopefully those mods will make the MBC+A (which is currently in transit) that much better.


Sorry for taking this sooo off topic, I just wanted to share my excitement

:)

...So, the obvious question is would the K&N drop in filter and funnel mod help an n.a. 2.3? If anyone could use more pep, it's we n.a. owners. And it would be nice if our cars went faster too.

We can go fast too, it just takes us longer ;) .

Jeff, for us I think a K&N drop in filter, an enlarged cold air intake on the filter box, and the genuinesaab intake is the best best for added power. Plus I did find a +10 hp modified ECU.

I too now have the K+N as i got tired of waiting for the cone one to come in at GenuineSaab. I thought i noticed a difference too although to be honest i should as my old air filter was a bout 3 moths past due being changed and very very dirty :)

That you will notice!!!
Did you do this Scott?
"Cut it out with a soldering iron" seems a bit ghetto to me. Hehehe And then attach it by melting the plastic with the iron?!? Got to be a better way then that, no?
Willing to try it, though.

I would think, as Slaab said, this would be one of the first things you NA guys should do.

//EDIT// Should mention I noticed this tiny bit of improvement yesterday...when it was 90 degrees out.

Is there any emissions or mpg penalty for doing these mods? These are big advantages for we n.a. types, and I would hate to loose them.

No idea about MPG but I am quite sure there is no change to the emissions since your car uses the extra air. It doesn't just push it out the exhaust.

I'm willing to chop my box up, if I don't like it, $50 to the local salvage yard gets me another complete box. What will make it even sweeter is that I'll be able to meter the air with the Carchip. I have plenty of baseline values saved at various speeds. I was this close (|---| gotta admit thats pretty close!) to buying the intake/throttle body pipe this morning, but then I chickened out.

But my thought without seeing that sie was to also use a soldering iron to cut the thing out, so maybe it isn't too ghetto. I am curious why he only went so far as to cut just around the stock pipe's mount. Why not go with a larger diameter, like the whole diameter of that face? Perhaps it has something to do with that fact that air would then become restricted on the outlet side of the air box? And why does it look so short to me? It must still get out of the engine bay enought that is doesn't just suck warm engine heat. Its funny because with my experimenting of air ramming methods funneling the end of the plastic intake inlet pipe, I used a section of the same funnel, guess I'll have to go pick up another.

I had thought that maybe the funnel faced forward, and acted like a scoop. Therefore enlarging the opening wouldn't be so necessary?

I might pick up the k&n filter, though the idea of smaller grit particles getting through causes me some stress. Maybe I'll put a piece of double sided tape on the clean air side and see what it picks up.

That's why I hemmed and hawed and hemmed and hawed. Keep hearing and reading all these discussions about how the KN isn't as good as the paper OEM one. Foam vs paper vs cones vs whatever else.
I just finally came to this conclusion:
KN has been around a looong time. They've been makling filters forever.
Now if they were really that bad for a turbo car, wouldn't someone somewhere have some concrete evidence of this?
Someone would have sued KN by now for a blown turbo. That would be all over the net. Surely someone here would have mentioned it. Surely KN would have some disclaimer re: turbo cars so they don't get sued.
Yet there is hardly any (in fact none that I could find) concrete evidence that a KN foam filter is bad for a turbo. I simply don't buy it that I am putting my turbo at risk.

I have an N.A 900 2.0 and I have been wondering about mods, 3" mod sounds good, as does K&N, may consider it, i guess worst case scenario, it makes it run rough as a dog and you have to put it back the way it was...may try it when i have a spare afternoon, which at this rate aint gonna be till next year!


:lol:

OK, deed done. That was fun. Cut the 3" piece of the funnel, but left the larger diameter portion alone. That part is just a little big, its hitting the back of the headlight cover. I think it all might need some adjusting. Air is being sucked from right behind the headlight, as opposed to towards the fog light, guess I'll have to play with the angles a bit. Took the car out for a ride, notice an increase in air noise at certain RPMs, even a little bit of a vibration frequency forms with it. Will have to do a commute or two before I average out the air flow rates.

I didn't do dips thing yet, but I did do a 4" to 3" to 2.5" intake.:eek: :roll:

I will be doing this once we get settled into the new house and have a couple of spare minutes on my hands.

I just finished Dip's funnel mod. I'm gonna install it back in tomorrow so the silicone has time to cure overnight. I used a soldering gun to remove the the original fitting and it worked well. To hold the funnel in place I cut pieces of the old fitting and melted them to fill in the gaps. I'm looking forward to seeing how much of a difference it'll make (don't have a K&N filter at this time). My next task is to remove the turbo silencer.
