I am interested in getting the FIPK part number 57-2545 for my 04 Cobra but, I have a few questions. 1) They (K&N) do not list a part number for the 04 Cobra, can I use the 03 part? 2) They (K&N) claim to have a 30.2 hp increase over the stock filter, this sounds strange to me, can anyone varify this? 3) this one os for anyone who has installed this on their car. Is drilling necessary?
The 03 will work on the 04. The instructions require one hole to be drilled as a support, but most people don't do it as it uses a bracket that mounts to a factory location. It seems to give it enough support.
You will see a nice S.O.T.P. difference. The tuner in my area says that it and the Densecharger average about 20-25 to the wheels.
It will also enhance the blower whine. I believe that it's worth it. With that and a cat-back, you will see ~400 hp to the wheels.
S.O.T.P. Seat Of The Pants (aka...the old butt meter)
The Densecharger is another CAI that mounts in the fenderwell. It typicaaly dyno's the highest #'s on our cars with the K&N FIPK coming in a close second. There is only a few HP difference, but the price and ease of installation usually lets the K&N win out.

S.O.T.P. = seat of the pants, the best dyno out there Densecharger= a cold air intake that uses plastic material rather than metal, meaning the material does not heat up like meatl keeping intake temps. cooler and providing more horsepower.

DnB. if your on a budget, you can get a cheap metal intake, and wrap it in fiberglass tape. it will work just like the densecharger, but will cost 1/3 as much.
Thanks for the heads up on the drilling. So you are saying that it might not be necessary?

I have talked to people who have done it both ways. Some are anal about drilling holes in a new car. The hole is drilled in a corner of the fenderwell. The heat shield attaches to it. The shield also attaches to a hole already there, plus a bracket that is mounted piggyback on a radiator support I believe.
I did not drill the hole as I thought the other two gave it plenty of support.
Just about any CAI you choose will probably require drilling a hole.
Why was this moved? It was originally posted in the Pipes, Boost and juice forum which the discription states "Talk about Exhaust, Nitrous, Blowers, Turbos, Superchargers... whatever makes you go faster!!" and the FIPK makes the car go faster. I don't understand, please help. (I am not trying to be a smart ass or anything like that, I just want to know for future posts.)
rtm,
I think I am one of those anal guys, I don't want to put any holes in my car.
Thanks for your reply and you attempt at answering my question. However, I think don't think I agree with you. K&N state on their web site that their FIPK adds 30.2 HP over the stock filter, if this is true than an intake pipe is a power adding devise. Additionally, if you think of the engine as a whole the intake is just as important as an exhaust system. People change the exhaust to have better flow thus increasing HP. I would think one could think of an intake pipe in the same way. If we did not gain power than why change the pipe?
Jeff, im pretty sure that Nomocobra is talking about extreme power adders like a supercharger, turbo, nitrous. A air intake is considered to be just a "bolt on part" along with exhaust. If i am wrong someone please correct me so i will know myself.
Thanks for your reply. I understand that the nitrous, turbos and supercharger all add a lot of power to a vehicle. If there were just a room for those items I would not have included the FIPK in that room. That being said, the FIPK is equally important as exhaust. As a matter of fact, the HP gain in my cat-back system is less than the gain I received from the FIPK intake. So I bring the question up again, how is an intake system not considered a performance part if it actually increases HP and torque?
Anyways, I picked up my FIPK yesterday and from what I could tell, I did gain more HP. I also noticed that I am getting more boost, so the supercharger must be breathing a little better. I have to take my car into the shop to have some warranty work done to it, I would assume that I have to put the factory intake system back on the vehicle before I take it in? I am sure that the FIPK would void my warranty.
If it is any way related to the K&N and your Dealer is a hard a$$, I would say to remove it.
By the way, I have talked to 3 SVT dealers in my area who said that they would only consider a pulley and tune to be a deciding factor.
The dealer that I take my car to knows that I have the mods listed. He said that they would still work with me, but if I had any work that could relate to the mod that they would have to charge me.
There are currently 3 things which need to be fixed. 1) There is a vacuum hose which is split at one end. 2) The front corner of the trunk rubs the body when opening the trunk, this has actually rubbed off the paint. 3) The rubber on the peddels are coming off.
Nothing to do with the intake or exhaust of the car. I guess I was thinking more down the road. For example, if something were to happen to the blower I wouldn't want the dealer to look back and say that the FIPK caused the problem with the blower.
Yeah, I can see your point. I guess it really comes down to what you think is the best. If you have any doubts at all, I would just remove it. It will not take that long anyway.
I would also suggest trying to get "hooked up". The small Mustang club that I am a member of has a few 03-04 Cobras that are modded. First thing I did was ask where they took their cars for any service work. Now I go to the place that I mentioned in the other post that knows my mods and said they would be fair to me.

In this reply you stated that you have attached your FIPK in 2 locations, is this true? Mine only had the ability to attach in 2 locations, 1 being the radiator and the other being the drilled hole. As I said, I am not into drilling my new car, leads to rust down the line. But, I think I need more than 1 attachment, so I was thinking on using double sided tape or something to hold the bracket which requires drilling in place of drilling.
Let me know if yours has 3 attachemnt locations, if possible, could you take a picture and post it on here, I would like to see what it looks like. I will do the same for mine later today, and we can see what the difference is.
I'm sorry. You are completely right. I pulled out my instructions and they were as you said. I would post a pic but I currently have my car in the shop. I had it wrong. I am only using the one support and it seems to be doing fine.
That's a good idea about the tape though. I am going to look at that.
The reason my car is in the shop is I developed a slight creaking noise in the steering rack that can be heard when turning the wheels to the right. It turns out that there is a TSB on it. They are replacing some bushings and sleeves. It does not hurt the car and you can barely hear it. But I want things right.
Thanks for your e-mail. I noticed today that I am getting a air pressure release from somewhere when the A/C compressor comes on. It might just be the sound of the compressor but it really sounds like an air leak for a second like a "pppsssttt". Also, after I out my exhaust on I notice a little pop sound when I start the car.
The TSB you are talking about is that Technical Service Bulletin? If it is, I would think I would have to have my car checked. Any other things you found on your car that I should pay attention to?

Does the FIPK really work? - 
I am going to look at that.
