That's because you don't run huge injectors, it really is not made for a stock 6.0...

 

LOL, did it get a lil squirrely when it shift into 2nd gear? That's when it wakes up and gets fun.

sorry subzero...

 

Punched it at 45mph, and got sideways. I promptly returned the car to my friend before I owned it... lol

 

LOL, I can relate!

Sorry folks, back to K&N talk......

 

IIRC, it does retain the filter minder, but that only does any good if you're sure there are absolutely NO holes(even little ones)in the filter. By its very nature, a K&N is full of holes that are too large to filter the fine dust that can prematurely kill a turbo, or cylinder.

I'd take a WAG that any K&N 6.0l performance claims were based on MAF sensor manipulation with the intake tube cross section, not because its less restrictive than stock. Okay, that's really a SWAG.

Subzero, if you go over to the excursion main page there is a for free thread up on the top. You may want to post that your looking for a stock air box. You never know who may have one.

 

Great idea, I forgot about that!

I'm just going to say K&N probably made it all up. Truthfully stock injectors in our 6.0's are 135cc and from my understanding the stockers actually run closer to 100. The stock box does a great job in filtering but once you starting feeding it more fuel like I did you need to balance that out. That's all I'm saying, in my case I'm ok with the possible consequences. I'm so **** with my truck I've already have had my turbo totally cleaned out 2 twice in the last 26k miles and million mile filters are used for 12k miles then replaced.

 

Wish I had your talent, I've been on here for awhile and still can't figure out how to do that

 

That's not what K&N marketing says. I can take a picture of the box that's still in my garage to show their claims. LOL

(More SWAGs) But really, it's not about injectors, its about the turbo and how efficiently it can stuff air into the holes. Since our PCMs command power based on tables which account for variances in MAF, MAP, IATs, EBP, etc, you'd really only see more black smoke if you were starving the turbo, at only high power levels(close to, or WOT). We don't have O2, or any kind of combustion monitoring, so the PCM never does anything more than make good guesses for injector/turbo behavior based on running conditions. With that, if it calculates a certain intake charge density, it'll react with a certain amount of fuel/boost for a commanded level of power. The only time a less restrictive intake/filter would show a real benefit would be at CFM levels greater than what the stock system can deliver, and that level isn't typical, everyday driving. Up to that point a more restrictive intake system may cause the PCM to command more fuel to fine tune a desired level of boost, but that level of energy required for the difference is negligible compared to the energy it takes to charge the induction system(ie: the high side of the compressor is fighting against the compressor more than the low side is restricting it).


If it works for you, that's all that matters. It didn't for me.

Right or wrong, its more fun than talking about EGR valves.

poor subzero has his thread all jacked up...

 

What is this EGR thing you speak about? Lol

You make all good points

Right or wrong, I have it on, I don't worry about it and my EX is faster than your EX

 

Ah, https://www.ford-trucks.com/forums/1...le-thread.html

Brother, I don't know if you should have given me all this power
