Is it worth the money to go for some of the other CAI such as JLT or C & L performance that come with a tuner? is the HP increase worth it? Some here have posted that you still need to retune the system anyway with a K & N
I am planning on added a CAI and a cat back exhaust w/ x-pipe at the same time, what kind of HP total should I expect.
You do NOT need to re-tune with the K&N if you install as they suggest. If you chose to later you can get a tuner and remove the trap for the extra 10 or so HPs... If you want the max from the get go, not only power but throttle respnce etc. you can get any set up... C&L and JLT are showing the best numbers for the tuned kits, MMR is there to, dunno if JLT have fixed their mounting design problems?
You should be around 290 with that set up, depending dyno, tune and environment...

Let me see if I have this right now. If you install per directions and leave the HC filter on I do not need a tune but I will not see the approx 15 HP. Will only see very small HP increase until I get a tune that will add about 10 HP. Now, what is a tune?

kj-ciinci, I have read on these boards that cars built since April no longer have the HC trap, do you know if that is fact or fiction? (Mine was built in June I suppose I should get off my fat a## and go take a peak!!). If this is so did Ford change the factory tune at that time? The reason I ask is I wonder if the cars with the HC trap can use the K&N setup and factory tune without running lean because of the extra restriction caused by the HC trap. I am wondering if I bolt the K&N onto my recently built ride with no HC trap from the factory will the combo of no HC and K&N setup be to much and cause it to lean out.
The reason I am wishing to avoid a reflash so badly is that where I live we get some brutally cold weather and I do not wish to tinker with the factory tune as I need the smooth starts, nice stable idle, etc. Having said that I would also like an extra 15 hp, more is always better .
Thanks again for your time.

Wrong! You'll get the 15!
A tune is done with a tuner that is used to change your cars computers perimeters. Mostly engine perimeters but also auto tranny and some other stuff. For example with the the CAI, if you add too much air the cars computer cannot add enough fuel for your engine to run well and safe. With the tune you add fuel to the mix. Normally timing for the ignition is added at the same time to give the engine time to burn it all. Other things that are normally changed is the throttle resopnse, your throttle is electric and Ford has put a 'delay' in the reaction from your foot to the commputer and how the engine opens up. Most also move the red line cut-off and the torque limit a bit higher...

I think that is true, my car built end March had it but some guys just after me did not.
I'll also have to guess that Ford changed the F/A mixture when they removed these since the mix was dangerously lean with only removing the trap! See the links above...
The only way to know for sure is to get and install the part and then go get it dynoed and data logged... K&N might have the info on that too?
I'm from Finalnd and have had the brutal winters and I can promise you the tune will have no advararse effect on your driving! Regarding idling, if anything your engine will run smoother after a tune!

i have installed the k&n kit on my gt. it was very easy to install with basic hand tools. i honestly dont notic any huge hp gains but there is some, where u will really feel it is in pedal responce!! HUGE advantage!! also it seems to make the car sound stronger and meaner!
I purchased a drop in K&N filter for my previous car a 1987 Cavalier Z24. I noticed a sound difference, which made me feel I was going faster. When I had to clean it, I put a regular paper filter back in and I noticed that the car felt it had more bottom end torque. The accelerator felt more responsive with the paper filter. I will not be putting a K&N filter in my GT. Striclty Motorcraft filters will be going in.
Interesting quote from August 2005 edition of Muscle Mustangs and Fast Fords, page 124
... you can no longer just pop on a cone filter in place of the factory airbox assembly, nor can you reorient, reposition, or even rotate the factory mass air meter without dramatically altering the air/fuel curve. <snip> the factory mass air meter is so sensitive that even rotating it from its original inclination will create havoc. <more snip> Unless the new air intake system comes with a revised program for the ECU, don't be surprised if the air/fuel ratio is way out of whack the first time you take it to the dyno.
having read K&N's install instructions on their web page, they direct the consumer to take the mass air meter directly from the stock unit and pop it in the K&N. I guess they did a lot of research and testing to get it positioned just right so that it's not out of kilter.
by the way, the article was describing the Kenne Bell twin screw superchargers. They pumped out over 530 rwhp when the factory clutch packed it in.

I just put my K&N on last night and I think its a pretty nice upgrade without a tune. I can feel a difference and definatly hear one. The sound is much lower than before when stepping on the gas. The install was fairly simple with the exception of the rubber molding that was a pain in the A** to put on, my thumb still hurts.

This question is killing me: How do I tune it??? I have the Predator, and there are no specific custom tunes on their web page for the K&N and Predator kit, just the tune for the one with the C&L kit, and I do NOT have the C&L intake, but the black K&N intake. I've read that it's not emissions legal, but I still have the old parts. I had no HC trap on my Mustang. Ever. So the idea of failing emissions without one can not be true.

You'll have to get a tune from Diablo or K&N, or better yet, go to a shop, have it dynoed and professionally tuned with a data logger! This way you'll know for SURE how she runs and you won't have to worry about messing up your engine by running lean! They might also have the eq to check your exhaust etc. if you worry about emissions...??

The Canadian Price for the K&N CAI Kit is $316.76 plus 7% gst (or more depending on what province your in). MOPAC tells me that at the moment the manufacturer is showing a back order for this item of 3 -4 weeks due to high demand.
.
You'll get the 15!
