Just installed a new K & N filter today in my 02 LS V8 Sport. I was obviously interested because of the increased airflow leading to better fuel/hp performance. I mentioned this to my dad today and he said he put one into his 77 Porshe 911 but then took it out because he heard that the K & N filters allow in more small dust particles that can damage an engine over many thousands of miles moreso than a regularly replaced paper filter would. I searched around on the internet but found very little information on this.

Anyone have any knowledge or insight on this?

Thanks.
 
Total lie! If its so true dont you think KN would be pretty much out of business? I mean come on there products are simply the best. I believe that KN might let a lil more dust in but it has to be like a 1-1million ratio and at that rate you and I will be long gone before that motor feels the effects.

Sounds like something Fram would have started - You know the company that restricts air flow!!!
 
i was thinking just that myself


on thing i know never buy is a airfilter from walkmart all they have is fram
 
Fron worink in the dealership I have personlly seen K&N ruin Ford warranty's. Due to the fact that the oil contaminaties the maf, and shows a lean code, thus the check engine light comes on, and ruins the maf. I like K&N, but will keep it on my non maf vehicles, and quads.

K&N filters are what are called "boulders and bumblebees" filters--they're less restrictive because they're more porous than standard paper filters (eg, their filtering media isn't as fine as normal paper filters). They make up for the lack of filtering with the use of the oil, which, in theory, will attract the contminants that would otherwise pass through the relatively large holes in the filter.

By all accounts, if you're conscientious about the maintenance (namely, washing and re-oiling the filter according to the instructions), they're just fine.
 
Update: I have had my filter installed since yesterday. After I finished installing it, I backed it out of the driveway and then realized I had forgotten to reconnect the two electrical connections along the air intake immediately past the airbox. I reconnected these and then started the car back up. I then noticed that the engine light was on. I immediately consulted the manual to see what to do next. The manual stated that the engine light could indicate any number of temporary issues and that the light most likely will go out after a couple of driving cycles. Then, if the light doesn't go out, take the car in.

Is this the problem the previous poster was talking about? What is the maf? Should I switch back to a paper filter right away?

Thanks again.

Just disconnect the battery for 10 minutes or so, reconnect and you should be good to go. This is the whole reason you disconnect the battery to begin with, so the computer dosn't realize that you disconnected the MAF and air temp sensor. By not plugging everything back up the computer wasn't recieving a signal and though something was wrong. Don't rush next time.
