Im looking to modify my air box and maybe put a K&N kit on it?

Im thinking just remve the silencer and putting in a dropin filter.

pro-cons vs drop in and cold air kit.

Thanks RF

 

I asked the same question when I got my 06 FX4. Through much searching I decided to get the K&N conical kit with intake tube.

Using autotap I measured a 11hp increase. Can't say I feel the power increase.. but I can repeatedly measure a power difference.

Side note: The intake temps definately climb quickly at slow speeds or stopped. So this summer I'll be making a much better block off contraption to pull in cool air. Also worth noting.. I've been keeping and eye on how wet the area gets during rain and snow. It gets a fair amount actually so consider water infiltration what ever you do.

Before i got my MAC intake, i had the airbox tube removed and a K&N drop in air filter.

I ran that for a year so so. When i put my MAC intake on, there was no difference between the MAC and my K&N drop in.

If you want a cheap/decent upgrade, keep your factory set-up, remove the airbox tube, and add a aftermarket drop in filter.

 

I would agree that there isn't $300 worth of "value" in the Kit I have. But I do think it's able to flow more laminar at upper rpms. You can't beat a conical filter when it comes to that.

Without doing a back to back who really knows. Just the fact that I measured a 11hp increase does show that there is potential in opening up the stock setup.

I just put in a K&N filter. I weighed the value for me. $300 dollars for 11 HP is about a 4% increase. For what I do with my truck it's not worth the cost.

So how do you like your AutoTap? I get their emails is find their info good. Just the cost for the reward. I have 4400 miles on my truck and a 5 year warranty. I think it would be nice to have after the warranty runs out and I will do some of my own repairs or I will be knowledgable in what the tasks the shopp has to perform and justify the cost of repair. Warranty work i don't care about cost just down time.

 

I have the ford option for autotap which is nice for data logging and such. (bought it for my lightning more than anything else)

I will say this.. I've wound up using it for many different cars. Even if you can't datalog you can see in real time most of the sensors. And that's awfully nice.

As far as the software it'self.. IMO it sucks. It's time consuming to use and crashes a lot until you learn what *not* to do. But for the price.. what else is there?

It works good on the ranger, lightning, and my 01 eldorado. So.. between that and having now learned what to do. I've overcome the frustration of operating it. Definately not a quick thing to just check your cars computer with.

i have drop in with the air silencer removed....I have had the whole intake system and i feel like it is about the same

 

I'm going to put in a drop in filter this summer along with some pullies. Hopefully I will feel a little more improvement in response along with my Borla.

 

your going my route.

let me know, ill do the same, about the outcome

 

thanks
