First question...does anyone run K&N cold air intake? I want to take few steps in moding the wagon, and cold air is an easy one. I want to do exhaust for sure, but don't know what the optimal setup would be. I don't know that I want to get rid of all of my cat's with a full system (UP,DP, Cat back). Can anyone give me a few reasons for or against removing all of my cats. I've heard that installing an up-pipe is a definite smart move. I also want to get a new exhaust (at least louder than stock). I'm sure that removing all cats and a full system is going to give me the most power gain, but what will give me the most power gain while also keeping atleast one cat? Or am I just dumb for wanting to keep one cat? Thinking Borla exhaust and Perrin UP and DP's. Mike
go to nasioc theres a thread about the mods you should and shouldnt do.. i cant think of what its called but they have alot of useful info..also there are some reviews...i think they did mention that cais are a waste of money and they do nothing noticable on a dyno
wrx wagon rigth? if it is, an intake system won't do you any good. There's not much gain from it and you can just use the money else where. A full turbo back system will be yur best pick to get the most out of your money.
Thanks, that's what I've heard. And yes, a wagon. I'd rather use the money on an exhaust if the cold air isn't going to help.
The other thing with a CAI is they can cause all kinds of problems if they're not set up right. The stock box will flow 300hp and you don't have to deal with a pissed off MAF sensor or worry about turbulence or leaning out the motor. Unlike a N/A car, it's one of the last things to do to get the most out of the car.
the k&n has been tested to work quite well with the stock ecu. there is a good threat over on nasioc showing decent compatability. i think it was nulhur (sp?) i would say if you want to do it, do it. it's a good mod to get your feet wet, and it gets you into the fenderliner pulling out the useless plastic garbage thats all up in there. just order 5 or 6 extra plastic trim fasteners from brian... those things suck. yes, i believe a rather stock 02 should see little to no restriction with the stock box, but i think there were ~stage 2~ wrx folks well under 300whp crushing after market turbo inlets tubes with the factory box installed. i'm not sure why anyone would have this sort of setup, but it illustrates the restrictive nature of the box, in higher HP applcations... on the intake, expect a little quicker throttle response, more bov/turbo spool noise. if you leave the ram air hole open its almost too loud. but thats about it. no 15whp, no shaving a 10th of your 1/4 mile. :lol for power, i'd look into a tbe, and saving up for turbo/injectors/pump/protune... although.... i think there are not alot of options for 02 Engin Management. can you run the AP?
People always start with CAI because they sound awesome. Even if it doesn't make power, if the sounds make you happy, that's all that matters. I had a friend put a homemade CAI with ram-air ducting (dryer venting) and a Nakayama exhaust on his Z24. Was it faster? Probably not. But it sounded like my 6R at WOT, and that was COOL.
Instead of spending money, why didn't you just hack off the bottom of the airbox? Cheaper, easier, and sounds the same.
Good point. :lol: But instead of blowing $500 on some part, worried if the name was etched on it to prove how much he spent, he made his own CAI, which for a n/a car probably did get some power. And he ran the tubing from behind a fog light he removed. He also measured everything so he got the MAF back in place. That was seven years ago, before anybody tuned Cavaliers. He showed a lot on ingenuity, which he then applied to a Jetta VR6. Hack off the airbox? Hmmm. I should just drill holes in my exhaust pipe- that'll make it nice and loud!
Gee, would have never thought someone would have bashed a mod that someone wanted to do on a forum. And, I have only had NA vehicles, on which they work just fine (G35 6MT...worked just fine). That's why I'm asking...and CAI is easy to install? If it does nothing, then I'm not going to add it...geesh.[/quote]
^agreed. Stop flaming the newbie please. I want this to be a place where anyone can ask any question no matter how simple or complex.
Who's flaming? I don't see anyone saying, "NO DONT DO IT NUB." Or anything like that. Esper, Disco, Shorten, Dynapar, Lvt, 2.5~, and Biker all had very useful information, I don't see what was offensive. Yes, they're very easy to install. Remove intake silencer, remove intake airbox assembly, add a coupler and inlet pipe, boom done.
no one is flamming here, they are all just telling him the potentials of the mod he wants to do and are also just giving advice as to where the money can go to give him the best bangs for his bucks. we're all mostly suggesting things, he doesnt have to not buy an intake or buy any of the things we suggested.
the KandN typhoon intake is one of the very very few that actually make a difference. if you do that ^^^^^^^^^^and the exhaust. you might want to consider a cobb accesport, or maybe reflash your ecu for what you had done to make sure you get your full power! Tim
i just went and got the blitz induction cover, works pretty good, but haven't really noticed any gains, just makes the engine sound a little bit more throaty up front. all it does is just replaces the bottom of the stock airbox, and gives it a little better flow. the good thing is, it doesn't throw off the maf, so no dummy lights going off.
Ide recomend the Godspeed Blitz SUS intake, he modify's them so it wont trigger a CEL and I had this on my stage 2 WRX and noticed some gains, faster spool ect. and had no problems. ( plus it sounds cool ) From www.godspeedinc.com, "The ONLY intake with full velocity stack. We custom rolled the aluminum to give it the best flow possible. We left the MAF diameter same as stock to not adversely affect AF mixtures and keep the ECU happy and safe. We also offer the intake with a standard K&N filter at no additional charge. This intake will also work with the APS FMIC kits. "
^^OMFG, that looks hot ^^ Not an intake man myself, but if I had to do it again, I would get that one. Nice piece. I had a Blitz Panel filter before I got my FMIC, and it worked great. And hacking the airbox can ease some of the restriction on the intake. Also, instead of getting a CAI or whatever that removes the snorkus (that works like a CAI anyway) you might want to consider going with a Samco turbo inlet tube and post-MAF tube. Or even the Perrin versions of it. That will allow the air to move a little more smoothly pre-turbo, and it will also resist the collapsing that DiscoPope spoke of. Just a thought.

I know that I want to add exhaust and accessport, so I'll be saving up for those. I was just itching to make a mod to my car last weekend, and exhaust/accessport would take some time (not to mention more money) to get. So, to scratch the itch, I bought an STI short throw and installed it. Might not give the car more power...but shifting certainly feels a lot better. If I get beyond the exhaust and accessport, I'll probably mess with the air intake...and thanks for the suggestions. Mike
I just removed my CAI... put back the stock intake.. not a whole lot of performance difference.. but man sure is quieter fromt eh engine bay except for the BOV... may sell it for $20... any interest...
What do you think the Stage 3 Weight Reduction on my SHO is? Illinois winters! Rust makes my car faster every year. Of course, the rust is offset by the full set of tools I keep in that car.
i just swish cheesed my air box and if all u care about is sound just do that. if i have any power gains its prob about as much as an intake
yes the godspeed one is teh seXXay. you can get his customised one with a standard k&n cotten filter the actual filtering ability of the wire mesh stuff is rather questionable..
I have/had that Blitz type filter on my old SVX. Sounded sweet at WOT. Not sure about any real gains, felt a little better. But I now have a Perrin short ram on my car, and everything runs fine. But do the exhaust and ecu first. Make sure you get a well made intake if you're going that route. Mine helps out at the very top RPM range, that's where my engine used to fall on it's face. I used to have a Blitz BOV, that came with the car, along with a bumch of other junk like a 5zigen cat back, aem cai and blitz power meter and boost controller. Sold everything but the power meter and boost controller, so I could get a scoobysport full exhaust, rims, and accessport. Only reason why I didn't sell the powermeter and boost controller is because I can't guarentee that I will have every part out and given to the buyer. So, don't want to screw anyone. So, what I'm trying to say is the kid that had the car befor me wasted a lot of his dad's money buying that crap. They didn't do anything for the car.
A few days ago I installed an AEM CAI on my fiance's 04 WRX Wagon. I gave it a good test drive before and after the install. Her car runs smoother at lower rpms, around 1500-3000. There is noticable power gains from 3500-6000 rpms. The intake also allows you to hear the turbo sounds, which she loves! She's happy, I'm happy.
