never even heard of race division, but judging by the looks of things, just stick with cobb

It's nearly the same price, and we all know what everyone thinks of the COBB (myself included).. I'd just get the COBB. If nothing else, the design seems better (and it probably sounds better too).

With Cobb you get a perfectly bended system plus a patented PRM air filter that will protect it from sucking hot air PLUS water.

The Cobb team would have designed a better filter if they could think of one since it would save some cash. This must mean that the filter PRM makes is simply the best they could dyno test.

If you have a MY98 2.5 RS, I don't believe that Cobb makes an intake for your model year due to problems with the MAF sensor. You will probably have to end up going to the Race Division intake, although I believe that Injen may also make one for your model year.

if you have a 98 or 99 w/ a maf you shouldn't even be running an intake unless you want to lean out your engine and screw it up in the long run...

I have a Cobb made to fit with the MAF and have no issues with it running lean, I did however run lean when using it with a short arm intake.

I'd go with the cobb, that intake doesn't look like anything special.

sorry to go off the original subject but,
how long does it take for the car to start runnig lean after the intake is on? i have had my short ram on my 98 legacy gt for a few months now and i havent had a problem with it.
i made the intake myself and all of the hoses are in the right place and the maf is still on (adapter). but besides having the adapter, the rest i did myself, will this really do some serious damage?

Thumbs down Uh oh

This is the Race Division intake for the '98-'99 Impreza RS 2.5L


Looks to me like there is no place for your MAF to fit.

And if that is in fact the intake for the '98-'99 Impreza, what makes it so different than a $50.00 Ebay cold-air intake for the RS??


Take these folks advice and stay away from them. Their name is catchy I must admit.

The race division intake that you are all discussing in this thread is the Injen intake.

Just thought I'll throw my 2 cents in there!

im planning on buying the ebay one sometime soon... then maybe an AFC down the road... i doubt i'll have trouble with my car running lean, since it runs really rich to begin with. my car btw is a 95 L with a 2.5 swap running off the 1.8 ecu. im gonna modify the intake to fit the MAF, and it should all be running well. ive heard of people running low 15's with CAI's and other basic stuff... my car weighs only 2500 lbs right now , and im gonna take a plasma cutter to the bumper beams soon... 14 seconds n/a? i hope so! lol

I heard from someone that Cobb is ready to release them to vendors...you might contact them for more information.
If not they are right on the edge of being released.

The problem isnt that the MAF system will cause ANY intake system to cause your motor to run lean, its that most intakes arent bent right and cause turbulent flow to your motor.

Its much easier to put out a half-arse intake that makes your car run lean and just not tell the buyer than to actually make it right the first time and spend the cash/time it requires. After all, most short rams that cause the MAF cars to run lean only do it at a certain point in the powerband...not the entire way up. The old JC Sports short ram intake (which I have ) only would lean the 98-99 cars at 5700-5900 rpms or so.

The Cobb intake that is being worked on will not require a tuning device, however, they are also working on an ECU reflash that will create a bit of power.

Hello Snagtastic,

Are you sure this is the case? In the Sport Compact Car article in which the JC Sports intake was tested and was running lean, they also tested the Minnam intake. The JC Sports and the Minnam intake both have the same bend but the JC Sports intake was the one that ran lean. Other intakes have a similar bend as well as the same intake tubing diameter as the JC Sports unit as well but they haven't ran into lean problems either.

SCC never came to a consensus as to why the JC Sports intake made the car run leaner. Only theories! (I need to quote from that article but it's at home and I'm at work).

i am running the injen intake on my MY99 with no problems.... this is the 5th intake i have used on my car (rallispec, ganzflo style, some custom jobs that i tried) ive experimented with making MAF brakets and everything and nothing seemed to work however with this intake i have yet to blow a MAF OR run lean. the injen is actually designed for the 98 so i had to mod mine a little to fit but its awesome. i dont know if the 98 will need fuel correcting (the 99 does with every other intake i have tried but not the injen) but in the event that you're running lean just pickup an AFC. theyre getting cheaper every day.

Thanks Nate! This is the kind of info people need to know. All the reading I've done (it's hard to keep up with everything here...ok..it's impossible) here and I thought that the JC Sports intake was the only intake that had the lean running condition problem. Good info!

BTW: I'm running a JC Sports intake on my Subaru XT6 and haven't ran into any lean problems. So I guess some of the older scoobies are exempt. The XT6 has a hot wire MAF that's similar to the 1999 Impreza.

ok guys let me try and help ya here a lil bit..

i myself have a injen intake on my 99rs and i had to lean things out about 4% to get it to run optimally which isnt really alot. I was just running a lil rich with it so i needed to correct it. I was using a a/f guage as well as an EGT guage. Then later hooked up to wideband to make sure everything was in order and i was spot on.

Now danzborin had a cobb modified intake on his 99rs... and we had to lean as much as 6% to get it to run optimally. This was using an a/f guage. So as you can see dont always believe what you are told.

And if you guys dont think my tuning skills are that great i have tuned well over 8 rs's with some pretty major mods and an safc. And all of them are running great no prob's.

hope this helps

Brian

Yeah, I'm pretty sure that I have the same exact CAI in my car. It's definitely injen. I'm a fan for injen intakes, they sound beasty and they're quality too! But I'd definitely get those CT headers.

Get the Injen CAI w/black powdercoat.

actually up top it was more like 10-15% leaner depending on the RPMs... so, as you can see, no run lean condition w/ the cobb... quite the opposite...
