Presumably you haven't taken the top cover off the engine yet or you probably wouldn't be asking this question.

Pull up on the top cover from the back end and then the front end. It may be stiff at first because there are four clips underneath that go over rubber mounts. Get your hands under the front or back end of the cover (both sides) and pull up gradually until it comes loose. Take the cover completely off including the air intake tubes that go to the front of the car. Those round air intake tubes just slide in and out at the two ends.

Once you have the engine cover off, turn it over and separate the filter box from the cover itself; there are screws that you will have to remove. Once this is done, you simply replace the stock filters inside with K & N type. Same size, same direction.

Then put everything back together again.

Hope that helps. The toughest part is lifting up on the cover and removing that for the first time.

 

I am going to replace the air filters in my 2004 Xfire with K&N. Can someone help me.....how do I open the air filter assembly. IT looks like there is a clip near the firewall. Thanks

 

I think the post right above your's should help...

 

Guys isent there a place like PEPBOYS that can supply in cold air induction deal also a chip i mean i raced a Porche cayan turbo & my car is brand new 230 milles at the time so i need more more more please let me know post me email me TonyLondonUk@aol.com

 

i think pep boys is the last place youll find a cold air for this car. the cayan turbo is no joke, tt v8.

 

i agree its a serouse peace but i am sure the man dident know how to drive it as we both had an open hiway was both a the red lite both had open road for about 4 milles but i got him he was 3 car lenths behind sounds silly but its true lol

 

I actually read most of this thread but if I am in extreme repetition please let me know.



Yes the German engineers messed up huge!



Common I don’t care why but they put the two filters on top of the engine bay like a great big heat sink. Then they made the intake tubes a very small diameter. Pathetic really. Yes the rest of the engine does a great job and the performance is there regardless.



I produce intake kits that actually perform and there are so many myths that you could spend all day trying to educate a person after you de-mythe’d there information base.



The basics are known more flow better performance. yes and no. Remember you need to take into account the engine and how optimized it already is. Intakes don’t add power they free up handicapped power.



Heat is very important with cars like the fwd Northstar that has a very hot engine bay. Actually dyno runs on a caddy short ram intake system reaped a loss in power. Turns out the flow difference was not enough to compensate for the heat.



The best cost effective heat cover was and has been thermal wrap. Flexible and can be molded to work as a sleeve.



Cold air boxes can work but plastic or aluminum alone still heats up and does not optimize the unit.



Ram air..ask anyone who works at Nasa ( yes even a janitor) they will laugh at you. Ram air requires alot more speed than we get with our standard runs.. now add the fact most ram air hoods open out at a part of the hood either with no airflow or worse vacuum. Most ram air hoods do not provide more than a good cold air intake.



Ram air set up on the front bumper or this general area is best and can be set up to avoid water ingestion.



I am doing an intake for a 500 series Mercedes and it has a similar system to the crossfire. I will show you when it’s done. Yes with dyno numbers.

Hey there Mr. Positive,
For one I'm not making a short ram air system, and two the highest PSI factor isn't necessarily near the ground. Actually in most cases the highest levels are found usually were your lights are. So Mercedes did in fact make a smart choice in were they ran there air-inlet hoses. The worst place you can put a filter is behind the radiator. Do to the multitude of honeycomb like chambers, the air is pretty much aubsorbed, or deflected. I tested the cars aero dynamics, in the search for the cars highest pressure area's. The stock inlets are pretty close to were you would find the hardest air flow. There were one, or two areas that would work justa as well, but would never work because of things like moisture, or debris. As far as heat is concerned I have heat defelcting sleeves that I have placed over the steel pipes. I take them off for the pictures, so you can have a better picture of what I was doing. I think the 500 has only has a single air hose, if I'm not mistaken. I think it runs down the same side as the coolant over flow tank is. Good luck with that one champ, oh and tell all those comedians at nasa I said hello for me. DME one of the biggest: hose/ tubing fabricators &, distributer companies in the world, doesn't think what I'm doing is very funny. Actually they are helping fund my efforts, in the development of this system. I guess we both don't share the same sense of humor, that NASA and yourself have.

 

Didn’t mean to come across as negative towards your ideas. I like what you have done. Very good. (Meant to be sincere)

Didn’t intend to compare your intake to the short intakes offered for on the Cadillac’s but wanted to mention the fact in some cases the issue of heat is so notable it makes the difference between gain and a tip to the loss side. Because the Mercedes system mentioned below is so lame even a warm air intake is better. In this case.

lol please don’t defend that Mercedes intake the location of the small hoses does not make up for the heat sink filter system... what is important is the engine is so over engineered that the intake is really an afterthought. On the 500 series they use fins on the intake as well .

I have been doing this for awhile and you have no need to be worried I have no intention to step on your toes...actually I thought I would be defending your idea from some who placed the stock system as such a great system. My system that I have been working on for this Benz has been gong on for a few weeks and done completely separately from your endeavor. I was only sharing because you seemed open and interested. If you make a great system I would rather buy it than copy it. Most intakes I make are not for mass use most are individual custom units.

The car (Benz) I am working with has two hoses and in the same basic location. Its all AMG anyway, as I am sure you know.

If AMG made the stock plastic case out of a phenolic material and used larger hoses it would work with the stock format. The material for the boxes should have to be at least 1/2 inch to actually provide the protection and the seal airtight.

Most don’t care and that’s fine for the Benz crowd.

Dude coming directly from the champ its ok I didn’t mean any malice.. Relax.

Champ.

 

Oh dude, is it coming across as worried. No I'm not worried about stepping on toes. I mean any body can do what ever they want. I'm just trying to take the performance of my car, and everyone elses up a notch or two. If you want to help in reaching that goal, by all means go for it.
Later Killer.

~this post is so bogus I'd rather take tabloids as fact. You added an air intake not a turbo/supercharger, the crossfire runs high 6's low 7's 0-60, there is noway adding an intake will cut your times that much, I believe the only thing you can beat is an AUTO rx8 because even the manual would womp you

 

Put your money were your mouth is cool guy

 

You know what's funny is that a lot of the RX-8 guys are in the same HP predicament that we are in. They want better and more engine upgrades because, in reality, their cars are about as fast as our cars (depending on how much they abuse the clutch), they just don't want to admit it.

 

You know, when i first read this rx8 owners b.s. post it bugged me, but now im just laughing because i know how slow rx8's are. Just head over to rx8club.com and check out their competition section. Most guys frun high 15's low 16's. One guy ran a low 14 and blew his tranny, and this is one of the most respected rx7 tuners out there, judge ito. I know because i used to have an rx7. They just try and talk ish so they can feel better about there cars being slow. at least they can port their motors easily though.............

just some examples. I kinda like the rx8, almost got it, but people lie too much. Automatic run real high 16's.

 

Oh I knew he must be joking, because there are three guys out here were I live that owne the RX8. Every one of them try to race me, and every single one of them have got beaten. I really didn't have to even try.My car just kept pulling away from them. I actually hoped for a lot more, coming from the late great RX7. Appearently mazdas going for a sportier sedan

 

Was that with or without the Double Duce? We are still eagerly awaiting your creation.

 

As far as I can remember, it was with. However the Duces technology has changed 100 time since the first encounter with the 8's.
