I wanted to get ya'lls opinions on which FIPK to go with.....K&N, Airaid, or Airforce. I know they are all basically the same, except some are more attrctive in appearance than others. Not showing the truck or anything just want the best performance. Any experiences or opinions would be appreciated.

 

I have the K&N version that has a plastic tube on it and I really like it. It isn't flashy but I don't run around with my hood open and dont show my truck.

I have heard others say that the AirAid has a bit better flow but I don't know how true this is. It does have the chrome tube but in my opinion looks out of place under the hood.

Look around at prices, and wait for some others to post there opinions here. K&N is a respectable company that has been doing this a long time and I feel that you get what you pay for.

 

Dcovell,

I have used K & N (not fipk) for about 12 years and tried something new when I bought my SCREW. I bought a CAI from MAC Products. It looks like an air-raid with the chrome. I ended up getting mine for $139.50 total including shipping directly from MAC. I have heard You can also get them from www.poorboysperformance.com . Just my opinion but I am very happy with the MAC and have about $150.00 extra to put into the truck.

Everyone will say that what they have is the best. It is my belief that the end result is getting more air into the engine. They all do that and use about the same filters. They should all be within 5 HP difference of each other.

I have asked many myself about the fibk systems. Almost everyone one said it was not worth the money as far as performance. I did buy the K&N air filter ($50) for my truck and my wife's explorer. We noticed such a better, smoother acceleration. It definately breathed much better.

Makes you wonder why ford does not put that in as stock?

Hope that helps.

So you are planning on getting the K&N FIPK sysytem? That's actually the one I'm leaning toward.......just haven't felt like I have found the best price yet.

Any suggestions on where to look and maybe some prices that ya'll have found would make it easier for me to know a good deal.

 

I have a K&N FPIK. MY 95 I had a K&N Gen I on it, and loved it also.

I noticed an increase in the perf doing the FPIK, and then another jump with the Cat back.

I have yet to run into too many people who don't like them, here or other wise.
I think it is 2 people who have put them on, and taken them off.

The post above is one of many I have seen that say they are not worth it, but have never put one in.

Another option is the air box mod, I have seen people do this, and be happy with it, but I think this is a compare to the stock air box, not a FPIK per say.

Another option for you, is to put in brake duct to the stock air box, and cut in the air intakes, so the stock has an additional draw point. Couple this with a K&N drop in filter, and you *could* be happy ?? I am in the process of making a shield around mine, with 2 3" drake ducts to give it that additional draw point exterior to the truck.
The stock air box mod to giv eyou a better idea, I think is floating around the L forrums somewhere.

 

Thanks SSCULLY.....I'm in no hurry to get one just yet, but I want to do some research on my own and hearing more of the info from this site will help.

Saw a K&N on ebay earlier with starting bid of 199....which sounded pretty good to me.

 

Troll the enigne post, you might find the thread that comes to mind where the memeber tokk of the k&N and put the sotck back on.

Take a look at ROUSHFAN-1's galery. This will give you an idea of what I am taking about with the duct part. He has a sweet setup for his air intake, but this will give you an idea of the duct work.
Also Don C. ( Don's Bolt ) has duct work in, for anotehr idea.

As for 199, I think I got mine from MacNeil Auto ( weathertech.com ). This was in May-2001, and I want to say it was 189.99, but I cannot find my reciept right away. Give them a call and ask, the numer is on the site. Another few to check are Summit and Jegs. Just a few more places to check.

Good luck with the research, any way you go, you should get better then 100% stock.

 

Another post I read from someone here on F150 said the metal tube versions are not as good functionally as the plastic. The metal tube absorbs engine heat better, thus heating the incoming air more.

 

I always wondered what would happen if you were to put a high CFM fan in the FIPK tube to force more air into the engin?

Would this mess up the mass airflow sensor or cuase other problems? I have never heard of this done before and I know the basics of a supercharger are to force more air into the engin, a fan may not come very close but even if it worked a little wouldn't a $20 fan be worth it?

Anyways I thought that I would ask, I wouldn't try it as I am not a enginer/mechanic just though I would ask...

 

Thats a big NO NO.......the fan can not keep up with the demand of air from the motor...........

 

About how much air does a engin suck in anyways in cubic feet per minute? Anyone out there know?

 

You just described a centrifuge s/c.
I think that is at 4 to 6 PSI ( I foget the spec right now ).
PSI as in pressurized system, the inline fan you seemed to describe for an HVAC system are about 100 CFM, non pressurized system. They also need the furnace blower behind them.

 

quicksilver 2,

After I sent the post, I saw my signature and changed it. I will probably not get the FIBK, but opt for the cat back upgrade.

thanks,

 

Um supercrew1, though that I would correct you now as you have made this mistake twice in this post.

It is a FIPK not FIBK.

Fuel Injection Performance Kit

This is K&Ns name for there filter replacement kit....

Not yellin or anything just making sure you have it right so you don't look stupid when you go into the parts store asking for one.
