aftermarket filter

[Bob Ayers]

I too have used them for a few years with no side effects to the MAF. I'm on a toss up performance wise. The 2.3 Duratech in my 05 Ranger seemed to benefit, while my 02 3.0 Ranger didn't. Don't get me wrong though, while the 05 seemed to benefit it wasn't anything to write home about.

Keep in mind the same size air filter is used for the 2.3L, 3.0L, and 4.0L. If the OEM paper filter will flow more air than the 4.0L will pull, it will flow way more air than a 2.3L will pull!!

Has anyone seen the dry re-usable filters?

The particular one I saw is sold by AEM and is supposed to be just as good as OE filters but with the re-usability of the K&N.

I think in a stock application, adding a mere air filter is pointless. But on some vehicles it really makes a difference. I just made a 4" cold air intake for my Buick the other day, the filter is a 4"x7" K&N cone mounted behind the front bumper. It did make a difference, but the only reason I did it is because its a required supporting modification for stepping down in supercharger pully sizes. Granted this is a little different then just slapping a replacement filter in it, considering I deleted the airbox and made a new induction tube.

I think it makes a difference with it being supercharged.

an old dog can learn new trix. i will stay with the paper element. I JUST WISH IT WAS "COOLER" LOOKING SO WHEN I OPENED MY HOOD IN THE MIDDLE OF NOWHERE THE ANIMALS WOULD ALL GO AWWWWWWWW.

i did run one in my mustang "street" and do run one in my 180000 mile contour "street" which me frackin step doughter put into a sand barrier

I didnt replace just the filter, I had the whole FIPK unit.

So, you paid big $$$ for more dirt, oil, and more noise!!

I have been using a K&N on one of my 2.9s for a while. It seems to help with throttle response a little bit, but the air suction through it is pretty damn loud. However I just removed the air box and hose and stuff and clamped the K&N onto the throttle body, so that is to be expected. I have never found anything other than dried gas residue in my intake.

Regarding cleaning and oiling. I hate cleaning that m-fing thing, takes 10 minutes to wash, four hours to dry, and oiling is messy. If I get into any mud or even deep dirty puddles, say goodbye clean filter. The box does say how to oil it, though - you just spray evenly along the length of the filter until it turns pink.

Overall, would I recommend it for a stock truck? No.

Hey there's this great new drug you've just gotta try.... it's called..... PLACEBO!

I prefer a paper filter, but I'll admit I HAVE a K&N that fits my stock airbox

Why? because it was easier than making a mount for a piece of window screen
to keep the bigger snowflakes out of the MAFfor winter operation.

I HAVE clogged up a paper element with snow in winter operation

I HAVE gotten a paper element damp and had it FREEZE (which adversely
affects it's flow capability)

So an UNOILED K&N has a place in my emergency kit, but I also
carry a NEW paper element.

I won't use any oiled filters on any of the engines under my ownership. Think about this folks, if the geometry is not changed at all, how might one increase the airflow through a filter? This 'performance gain' you speak of is merely a reduction in restriction. Doing this without changing the geometry constitutes less efficient filtration, meaning more debris is able to pass.

No thanks, I'll stick with my $5 paper filters.

Just another dude talkin shit with no real world experience. It's OK though, I run into your type all the time. No sense in arguing, I just brush it off and keep going. Stick to what you know, like photography

You obviously didn't know anything about mechanical principles, or you wouldn't have shelled out the big bucks on the FIPK!! Hopefully you
have learned by your mistake!!

I know enough to know that the factory doesn't always do shit properly. Such as sticking a 780CFM carb on a 302 that can't physically use that much air unless it was spinning 9K at 100% volumetric efficiency (which no naturally aspirated motor does). Or having a four cylinder/six cylinder motor breath through a 2" air horn on the factory airbox. Sure, I guess could have just wacked a big old hole in my stock airbox, but then I wouldn't have been able to coat my MAF sensor in oil, make a bunch of noise and fill my motor full of dirt like I wanted to Do you really consider $200 big bucks? It takes nearly that much to fill up my diesel.

You proved my point!!!!! Do you really think the carb forces the air into the engine? I guess that follows your thinking that the intake forces air into a EFI engine!!!

For your information, the 780CFM carb was used on the BOSS 302, and there was a version that did turn 9K RPMS!!!

apparently good research on what actually gets through a K&N is worthless because labs arent "the real world." Not everyone needs to "mod" their vehicle to make them feel special and running a stock paper filter never hurt any vehicle I've ever seen. The extra .5 horsepower I MIGHT gain is not worth the hassle of cleaning & oiling a reusable filter. not to mention my truck never sees anything higher than 55 mph so I don't need the extra filtering capacity that a K&N MIGHT get me. I have more fun crawling at under 10 mph then I ever would going fast. Call me old if you want but I'm 22 years old, I just research what I do before I think its the best thing in the world.

on a side note: I like photography but I'm also a mechanic, does liking photography make me know any less about what I do? Please think before you assume. and by the way
