K&N

[THLONE]

Hi Folks,

Okay..not to malign K&N... the important metric on air filters is the number of grams of dirt the filter will hold. Aftermarket filters of a performance nature do not hold as much as a norm filter. This translates to more frequent filter changes. For me, I will stick with OEM filters as they were tested rigously.

Especially if you drive on a dirt road. Shorter Eng life.

The real benefit of a K&N filter for power is at 5K RPM and then it's only about 5 HP.

I am forgoing the CAI system as well, only the drop-in for me. For the reasons discussed above (negligible gains) and for offroading. I don't want to try and cross a river and suck in water with the CAI

Here is the link to the TCM. They don't seem to be claiming it adds any power, just better response. See the reviews. Tempting

I didn't see reviews on their page, just seems pricey. K&N has some type(s) of Boost Control modules too? I just wonder how many doodads I ant to daisy-chain here just to tweak my driving experience. Only way to justify is if significant mileage gains could be made.

Got one ! Bought it before I got the truck..

Has anyone have any real world experience with these on the new Rangers? Interested but not at the expense of more debris to the engine. Will the engine put the extra air flow to work?

I've had 1 in my truck since it was new. It certainly didn't hurt performance but honestly it just sounds better.

For those that don't like the 'oiled' filter,

There actually is a military standard test for filter efficiency. You expose the filter to mil-std sand /dust (yes there is such a thing) then count how many particles of each size make it through the filter. Knowing how much debris was flowed into the filter and how much and what size made it through, you then can determine the filter efficiency. The mil-std sand/dust is made up of a very specific ratio of specifically sized particles.
The test allows one to determine the filters particle filtration size, flow restriction and to estimate filter life. I've never seen where this type of testing was done on over the counter filters. Perhaps there is a similar SAE standard? What I can say is the filter medium does make a difference in particle filtration size and airflow restriction.

I ran a K&N drop in oiled filter in one of my jeeps,and what I seen in the air pipe pissed me off. I went and bought a stock filter and put that back in. I will never run an oiled filter again. I'll stay with dry filters,and top quality ones at that.

I just ordered this above. I just did my exhaust today<(muffler delete) and that made a YUUGE difference. Now I'll see if this dry filter does any improvements.

I'll probably order an AEM filter too. I run an oiled K&N on my Harley but I'd prefer a high flow dry filter.

I've run k&n on my scoots too,no harm,no foul. But my newest bike was a 79 flhc,and it didn't have any emissions on it. It was pretty much bullet proof. These turbo'd car and truck engines are a completely different animal.With all the emissions stuff,egr,turbos etc. I won't let any oil get in that if I can help it.Especially on the turbo. I put my AEM filter in yesterday,and I'm liking it.

My last V8 truck was a new 2011 silverado z71 with the 5.3. I put on Heartthrob catback duals and that really opened it up. Next I went with the Volant CAI with the powerflow dry filter. Yeehaww,that made it even more fun. I would have done that with the Roush cai,but I'm going to see what the next gen ranger,and colorado has to offer.So other than a bed liner,my mods are done
