Thanks........will do

 

good call--i'm probably completely wrong with the wot only statement!

it just doesn't make a lot of sense to me--i figure if i want the throttle to suck more air, i can just push the pedal further to open it...once it won't open any further it makes sense that a less restrictive filter will allow it to suck more than a more restrictive one

but, i'm sure there is some loss in the engine due to the resistance of the filter, and decreasing that resistance would understandably increase hp--i stand corrected

however, i will say with confidence that the hp gains are quite small and occur primarily at higher rpms than i drive other than when towing or pull grades--i do admit it feels as if the filter helps in those situations

 

Yea, really not noticable - I made my own intake - you need a smooth constant flow to notice anything - I made mine from schedual 40 but the best out there for the price is one made by "AIR FX" IMO. The MAF is contained in the original box and there air filters suck air from two ways in instead of the one way K&N - I'm going for one of those ASAP - I might have to bump my injectors to 24's to make them more compatible with that intake set up . It only costs $199 - but they don't advertise much , so they don't need to pay all that overhead.

 

i had a k&n kipk for a short time, but i didn't like the off-idle power compared to stock--the AIR FX sounds interesting, will check them out--thanks for the head's up jbrew!

 

No problem

 

I had a K&N on my old car, even with a factory turbo I couldn't feel a bit of difference over the stock one. If it wasn't a special order I would have returned it and got my $40 back.

 

After buying my truck used, I popped open the filter box and saw a K&N filter ... I also saw dust on the motor side of the intake tube A paper filter went in that day!!

 

Doesn't sound like it was oiled ...

 

The only way you can pull more air thru something is with bigger holes, or more holes, the oiling negates more smaller holes. K&N even advertises that they filter better as they get dirtier.

 

I pulled my K&N the other day - didn't trust it any more. Replaced it with a NAPA Gold paper filter (made by Wix), it was only $13 plus tax. I saw those Fram washables, I wouldn't trust a washable filter to work that doesn't have to be oiled.

 

Took the words right out of my mouth. Travel a dusty road and check to see how much that K & N allows into the throttle body. Just not worth slowly dusting a motor to save a couple bucks on a 30k truck

 

Well you guys are making some good points - I can see how oiled filters can let unwanted foreign matter run thru the motor - over time , it's pretty easy to see that this could be detrimental to your motors health. I run the OEM filter for most of my trucks life - switched to K&N a couple years ago. I found a film inside the metal MAF housing w/granular remnants stuck to the film. I ignored it then.

Thinking more about after reading thru the this thread - there's no way these particles should be found in there - specially when I over oiled it at the time and compromised my MAF.. WOW!! I hope I didn't do to much damage running the K&N - but I had to do some..One little grain of sand can score a cylinder wall. I think I'll pull a compression test again and compare it to last years readings. I have 231,000 miles and want to make it to 300,000 + with this motor..

Thank for the posts - I'll grab a WIX if they have one up at Carquest today..

 

Read the link and see what you think.

 

The K&N filters are not the best idea for dusty environments. They don't filter as well as a plain paper one which will eventually foul out your MAF causing lost performance. If you don't mind cleaning that every so often, then I guess you can save a little money by just cleaning and re-oiling. Then again, you're letting dust into the motor, and we all know how well dirt and internal engine components get along.

Claims of more HP and better mileage are BS. For a K&N intake system, yes, you can expect gains. From a drop-in filter? I don't think so.

I use a Purolator filter, because Advance always has them on sale. Then again, I don't have a MAF on my 5.8L. Just because on the 5.8L you have to unscrew instead of snap open the airbox it takes a whopping 5 minutes to change.

 

Just mixed the rest of my K&N Filter oil with half a bottle of Armoral - works great
