Well I decided to dive into my stock intake earlier today after spending all night last night looking at expensive aftermarket intake kits for around 300 bucks and couldnt decide what to do. So just decided Id save some money and tinker with the stock intake, and throw in a higher flowing filter an see what it does. Went out in the garage and found everything I needed.

-I replaced the stock intake fender tube with a full 3 inch pvc pipe, painted it flat black and fitted it up real nice and snug. Used some black electrical tape on the tube at the ends, preinstall.. to help make a better seal without movement.
-Pulled off the resevior/silencer big contrapment on the stock filter tube, coverd it on the outside part with a thick round piece of rubber along with some eboxy sealant around it to seal it up around the covering of the hole,
-Sprayed the MAF sensor with CRC MAF cleaner, used Throttle body cleaner and sprayed the TB a little, since Im already there.
-Unhooked the battery, let the eboxy dry up, ran to advanceauto (used $10off coupon) bought the K&N drop in replacement- $50 bucks, came home put it all together, hooked up battery.

First time firing it up the wrench light came on and it wouldnt idle higher than 1k rpms, at this time I was wondering WTF? Finally I just turned it off for a min, then cut it back on and everything was completely fine, Im guessing it had something to do with the battery being unhooked for like an hour and half with clearing the computer..

But everythings fine and running great. And I have to say I can really tell a difference when getting on it,.. its straight clean acceleration no slight pulsing or almost hesitate feel like I kinda had before. It really opened up, sure it sounds cool but I wasnt going for sound. This along with my exhaust mod it may help complement one another, but Im completely satisfied and have to say forget the $300 bucks or the cheapos from ebay. Great cheap mod than I can feel. So Id suggested doing it over buying one, my truck is an 07 4.6L V8 RCSB 2wd along with full 3 inch custom catback with 14 inch magnaflow muffler 3'' SI/SO

 

The wrench light probably came on because you sprayed the MAF sensor, but dried off from the fast moving air.

 

Good day to you sir!

With utmost respect, and not to belittle yer efforts & all yer hard work ...

I believe the changes you are experiencing are largely due to the KAM reset, not the mods. Over time, Adaptive will bring you back to where you were.

- Removing helmholtz chambers = no gains, possible more drone
- Inlet enlargement = a few ponies near redline only
- MAF cleaning = a great thing to do - good job there
- K&N drop-in = no gains; BUT, ensure you keep an eye on that MAF for contamination, as some of these are over-oiled from the factory. (Best practice is to clean/re-oil properly when you first get it).

Now, put that money you saved towards a custom tuner for some real gains!

4.6Punisher- Yeah I thought that as well, but I sprayed the MAF literally about two hours before installing everything back together.. I think it may have been due to sprayin the TB a little to much on the TB blade and behind it, and it getting down in the TB.

I wanted to go with a non oil filter such as the afe dry flow but I already had the recharging kit from having prior kandn's so I just went and bought one..

MGDfan- So pretty much no gain is what your telling me huh..? hahah

 

PHP has said that this mod gives you around 7-10 horsepower.

 

Hello again.

Yer sir, unfortunately. It's been proven long ago that a drop-in, of any type, does not deliver any more performance. What you have done is save some money against future OEM paper filter changes.

Opening the inlet gets you perhaps 2-5 hp max, and only at the top end. And again, you really cannot detect this difference in a 5,000+ truck. Only a dyno or a timeslip will tell you. And, atmospheric changes can affect power at least as much.

One other thing - for the 4.6, that exhaust has moved yer torque peak higher up the powerband - not optimal for the small V8. Gains from that will also largely be at the top end, but low-end grunt will suffer some. A 2.5" system would have been a better choice. Just an observation.

These are facts, not conjecture. I offer them unconditionally and without rancor. please do not take offense, as none was intended.

Thanks.

Cheers & best regards;

Hi Mr. Punisher.

Thanks for the correction.

Would you happen to know if that is for a 5.4 or a 4.6?

Here is a plot for a 5.4 (09', with the factory's much-improved, larger airbox and custom tuning)



Mostly upper-end - and remember the tuning is in place and this is a VCT engine.

I do not think the 4.6 responds quite as well, hence my initial figures. They may well be conservative, but I'd like to see the numbers.

Thanks!

Cheers!

MGD- Dont know what your trying to prove here but dude just shut up, how you goin to argue with me about a simple exhaust and intake mod that I choose to do and that I can tell a difference in, this isnt your truck, you dont drive it, spend your time else where your not proving anything. And a measly .5 difference in a damn single in/out exhaust setup is not goin to make a damn on a stock *** 4.6 in a truck please s/t/f/u/, same for the intake mod. What I did is slightly no different than an aftermarket design, which different aftermarket brands show results anywhere from 10-14hp, I aint sayin I gained a whopin 14, but I know what I feel. You aint telling me anything, your spinning your wheels and wasting time, I know what I feel hence me sharing my experience with doing this. My truck I know what I feel. I have done this same mod on my prior S10, except with an s10 its a drop in panel kandn filter, I modded the airbox I didnt feel any difference whatsoever with the S10, but with this truck I can tell.

And (NO) it has nothing to do with the computer being cleared either, I installed my full stereo system about 2 months ago and had my battery unhooked for about an hour and half when doing it, and truck did not act like this when I hooked it back up, so theres your know it all on that accusation.

You sound stupid arguing about something like this you have no control over.

 

I completely forgot about that, once again you win.

I do disagree about his 3" exhaust. 2.5" is stock and it's pretty restrictive. 3" SISO is perfect for low end grunt.

 

I don't think there is a single person on this website that can feel a 10 horsepower increase, period. Its hard to feel 10 horsepower on any full size vehicle, let alone a 6000# truck....
If you feel good about the changes you made that is great!!

 

Afetr reading all the threads about CAI from you guys, I'm almost affraid to ask but hear goes anyway.
I have been considering changing my truck over to a CAI system mainly because it was recommended to me to do so. Since I'm not the "sharpest pencil in the box" I depend on others suggestions to better my truck.
What is the difference in the two brands so fas as I'm told to be the best, ie: K&E or AFE, using Dry or Oil Based, and lastly, Enclosed or not enclosed?
Not looking for getting my *** chewed on this but jsut some good input, ok guys...

 

Alright, let me give you the run down about CAI's. Thank god I'm bored at work...

Your basic CAI would be a K&N or an AEM. They have oiled filters and an open element. These are not real CAI's, just expensive tubes with an open filter. They tend to suck in the hot engine bay air while sitting or in slow moving traffic, but at higher speeds they perform well.

The oiled filters are also not the greatest in the world. The manufactures say "better flowing" and "more power", but the power difference in oiled filter and OEM Motorcraft paper filters is laughably small. The fractionally better flowing filters also sacrifice filtering capabilities to allow the better flow. There is also the chance that over oiling of the filter can happen, causing oil to build up on the MAF sensor and possibly ruining it. The benefits of oiled filters is that they generally last forever, or as long as you want to keep cleaning and re-oiling it.

Now we can discuss the better CAI's like S&B or Volants. These CAI's are (usually) enclosed filters. This gaurantees that cooler air from outside the engine bay is being sucked in at all times. This means that even when your stuck in traffic, your engine is getting cooler air, which means more power. S&B CAI's still use oiled filters, but the whole assembly is cheaper than any K&N CAI and better quality.Volant CAI's have the option of using one of their higher end dry filters that flows well and still filters well, but is the most expensive.

If you want the best of the best, and you've got the cash, Volant might be what you want. If you don't want the most expensive CAI and 2nd place is good enough for you, S&B is it. I can't recommend K&N or AEM just because they are overpriced open element CAI's. Also look into the $15 Gotts Intake, best value in the entire CAI market.

 

Thanks for the information and advice.
