CAI

I am planning to put CAI and Y-pipe this summer. Currently i have the plain square K&N filter that replaces the stock one. If someone can point me out if injen intakes have K&N filter on them or some paper junk. If injen doesnt have K&N filter what would be a good intake brand to buy or can i buy the cone filter seperate on put it on the injen piping. Also where would be a good place to get these parts. Ebay? custommaxima? some other?

I read alot on org about possible MAF sensor problems encountered following the intake install (especially on 2k2s). Is this concern due to clumsy installs or there is really a problem with MAF and intake? If so, what can i do to prevent MAF sensor damage prior to installing it? After intake installation is it necessary to restart the computer by unplugging the battery?

Y-PIPE

i read alot that i should only get cattman regardless of price premium? true or false? i have a $25 FSTB from ebay and works just like the stillen one? is this the same deal? i really dont want to spend extra dough if i dont have to, so someone please advise whether namebrands are really better or not. what potential problems i may run into during the install aside really rusty screws?

i plan to do all installs by myself.

thanks

 

I never have liked the Ingen intake. It is too close to the exhaust and the ground. I would only go with a true CAI aka, PR or Cattman. They are outside of the engine bay and nice and protected. You can get either a K&N filter or a monster flow crap foam filter.

As for a y-pipe I dont have any experience with anything other than the Cattman. The fitment was great and sounds nice too. I only finished the install last night, so I cant really comment on power gains.

I wouldent think you would have too many problems with rusted on bolts since you are a 2k2, but I dont know how bad things are where you live. Just spray some WD-40 on your nuts (HeHe) the few days before you install. Only tip is to try to get some lube on the EM/ front pre-cat connection, because I sheared off a bolt while trying to loosen that. Just make sure you have pleanty of socket extensions and one of those little swivel joint things (sorry I cant think of what it is called, but it allows the socket to pivot).

 

I think the MAF failures are due to over oiled filters. A light coat should do fine. You dont want the oil to get on the MAF sensor.

 

I have a Place Racing CAI (can't really argue that it's not one of the best) and a Budget Y Pipe ($198 shipped) and I couldn't be happier with the sound, performance, and fitment...people will say cattman but i don't see how there can be any difference bc they are both stainless steel and mandrel bent with flex section etc...i love mine so i say go for the budget but that's just my opinion.

 

here is the think.. for CAI .. you will loose alot of low end torque.. but thats just your preference..
the injen CAI comes with a small cone.. you can purchase a 8" k&n or apexi cone from Cobymody (bryan) for a very good price... ebay even sells k&n cones...

i personally prefer the BERK intake system since i still have some low end torque remaining..


now as for Y PIPE
since you have a 2k2 .. cattman is probably the best you will get.. gain and price..
warpspeed y pipes dont give you much gain as they were suppose to.. only 5 hp

but cattman is the best for 2k2-2k3.. 15-20 hp depending on mods.
make sure u disconnect your battery before your install


installin the intake.. is fairly simple and straight foward is u have little experience and common sense..

as for y pipe... you need to know what you are doing..
and preferably have some one experience with you..
took me 4 hours to do it.. way too many nuts...

you wont notice the gain right away since the ECU needs to adjust.. take about 2-5 days..

if you are not experienced install mods.. i would suggest to play it safe .. get the y pipe installed at a local shop shoudl be about 60 bucks ... and watch what they are doing..

i hope this is some help

I wish there were some dyno comparisons between intakes.

From what I have heard you actually lose less low end power with a CAI but dont gain quite as much up top when compared to a short WAI. I thought the longer intake piping promoted air velocity for low down torque, but created more restriction in the high RPMs... So in essence the opposite of what you are saying

Is there a physics major in the house???

 

I love my cattman Y. I have a frankencar intake, and it sounds GREAT!

 

Man here we go again. Please explain why a CAI would lose ANY lowend at all?

 

LOL, so true man, this topic on this forum shows up as much as Iraq does on the daily news.....

 

I have a Cattman Y and Wsp B on my Max. For the past year, I've been swapping out my Injen and the stock intake on what seems to be a regular basis. I think the Injen would probably be much better if I wasn't an auto. At this point, I'm leaving the stock intake in with a K&N filter. It fits my needs.

 

Umm... Thats kind of what I am saying. You would lose low end if you dont have enough intake air velocity. Smaller tubing= more intake velocity, but unfortunately more restriction (especially up top where the engine it trying to take in a lot of air). It is a compromise between low RPM velocity and the low restriction you want at high RPMs. Hence why a variable intake is so effective, it is the best of both worlds.

POP chargers shorten the intake path losing low end, but at high RPMs it is great because there is like no restriction.

CAIs are a lot longer than a POP charger and close in length to the stock intake track, so you once again get the best of both worlds: Close in length to the stock track for good velocity (low end power), and no air box or sharp turns for lower restrction (top end power).

That is how I see it in theory anyway.

 

I have the Injen intake and I like it! I do not think the lowend power is lost from longer tubing. If you look at the stock intake tubing, it is much more narrower and restrict airflows to the engine while the car is at station.

From my research (both from reading numerous threads on this forum & other interent sources) on this topic. The CAIs, will have the same lowend performance as stock airbox but will gain a little more power and noises at WOT or higher engine speed. As for the WAIs, lowend power will be lost if the underhood temper is hot. The WAIs will perform better than both the CAIs or stock airbox at highway speed because of its short tubing. However, engine noise will be much louder...though some people see it as part of a performance enhancer...I don't!

My only fear with the Injen intake is a possible of hydrolocking of the engine if run over a flooded/puddle of water...which I doubted will happen. I always try to avoid driving under raining condition or choose an alternate route if i must be driving on the road.
