I am considering putting a K&N system on my 01 SD V10, is it really that helpful, worth the money, or a waste of time? I use the truck to tow my 7000# camper and my brother occasionally (when his chev can't handle the pressure) uses it to tow a 5000# kart trailer. So we are averaging around 15-20K miles a year. Ive heard different arguments whether its worth it or not.
What's your opinion?

Thanks,
Scott

 

For a gas motor, i think you will be ok. If it was a diesel, it would be a bad idea

 

Don't do it!!!!!!!!! waste of money and K&n don't filter well...

 

I put a K&N cold air intake on my 06 PSD and never had problem and I think it gave it some power when I need to. I also had one on my 02 F-150 with 5.4l and liked it. I don't think it's waste of money.

 

I liked my K+N on the 01 PS, but after hearing they dont work to well, I traded it out for another cone filter

 

I had one on my diesel and I was not pleased with the results. Could not really tell much power wise and it seemed like the filter would be really dirty again right after cleaning. Couldn't even tell it had been cleaned. But I don't know how it would fair on a gas engine.

 

Worth the money. Do the complete cold air intake, not just the factory filter replacement. K&N has a somewhat bad rap on here, but I can tell you from personal experience on two gas V8's I am very happy with the results and the price is right.

 

K&N+powerstroke=dusted turbo; K&N+V10=more airflow

In a diesel I would say you have to be nuts, in a gas it's not that big of deal.

 

I've had my K&N FIPK for several years on my V10 with no problems. It is easily maintained and helps in the upper rpm range. The intake would be good for pulling heavy because of the fact that a gasser will spend some time in the upper rpm range on hills and such.

 

Thanks to everybody for their responses.

 

I'm goin' on 7 years with my K&N kit on my V10, never had any issues or complaints.

 

I have a problem with a filter that says in the instructions " the dirtyer it gets the better it filters ". I ran one on my truck for a while, after hearing all the neg about it I finally looked into the tube and it was white with dust. Just my observation on a diesel truck.

 

FACT: new K&N

FACT: i do used oil analysis

FACT: oil came back bad due to air filtration (means dirt/dust getting in engine)

FACT: removed K&N, used normal paper filter

FACT: subsequent used oil analysis showed no problems

Your decision if you want your engine digesting dirt/dust for MAYBE 5 HP of that.

If you want to do intake right for normal road use, i'd suggest looking into ram air scoop with good filtration or a supercharger system.


Scientific analysis of oil tells you a lot about many things. So does dyno time BUT even dynos (yes even th best ones) can be off by a few HP as can the condition of the car (heat soak), etc.

 

A diesel has NO throttle.... plus a turbocharger to cram air into the engine. It draws tremendous amounts of air and needs a low-restriction intake. A diesel is also more sensitive to dirty air than a gas motor. Your money, your choice.... I'd stick with the stock air filter in the interest of engine longevity.

Now, a K&N on a gasser..... Gas engines have a throttle, and the only time you really benefit from a low-restriction intake is at or near WOT. How much time do you spend with your foot on the floor? Dragstrip, OK.... street, only if ya wanna smoke 'em away from the stoplight.

My 2 cent's worth.... your mileage may vary.

Remember..... REAL trucks don't have sparkplugs.

 

Well, before this gets into the over-argued gas vs. diesel thread, here's 9 pages of comments about the K&N from the V10 forum...
