Have a K&N with the airbox mod and ram air on my 99 camaro. I have recharged the K&N twice and each time I find some dirt and grit particles in the airbox. They look small enough to be able to pass through the mesh in the filter and I bet some have.

Anyone using a high performance paper filter or does a stock paper filter work? Let me know what you are using.

Thanks

 

I use an ACCEL Kool Blue. I shake it out every couple of thousand miles. If anything has gotten through it, it hasn't hurt anything yet! I was going to go with a clear lid (and may still) and thought the blue filter would look cool.

 

I use the stock AC Delco filter in my car, and a Fram air filter in my wife's car, and in my oil analysis results both of these filters have proven to trap dirt very well. K&N air filters are terrible at stopping dirt from entering the engine.

 

Hey Patman,
Thanks to your recommendations I just started using only Baldwin filters in the Camaro. I decided to burn the K&N in my driveway after completing Baldwin filter change. It burns quite nicely

Thank You for setting me straight,

Tony

 

I ditched the K&N and now use a FRAM air filter.

 

I use Purolator because I flow tested 4 paper types
and it came in 2nd (behind the SLP Blackwing filter)
for best pressure drop. Slightly better than Fram,
both better than GM OE paper filter. I didn't test
any foam filters but won't be using them, either.

 

7 dollar Fram here!

 

I use a K&N filter, free mods on the air box and a SSRA to feed it. If you keep the K&N filter charged(Red), doesn't it adequately stop dirt & allow much more CFM to pass???

I atleast think that may be true & I'm more about making power. Maybe a paper filter is just as good, please advise, Fred

 

Same here. I haven't noticed any difference or loss of performance at all.

 

I don't think the K&N can stop small grit like sand or dirt, so I am going to change to the FRAM. Sand in the crankcase could be a BAD thing.

 

Holley filter here..it works ...very nice...and fits...tight..

 

I'm about to ditch my K&N

 

Wix has a filter with very deep pleats, in fact they're so deep some of them get slightly smashed on installation. Lots of surface area. I don't know the part number off hand.

 

Don't know if this is true or not, but when I did a search on here when I was trying to decide what filter to get a lot of guys said that the K&N is not made specifically for our cars. They said that's why it came with a foam strip, to make it fit tight.

 

Holley Powershot.

 

I just pulled my K&N and put in a Fram. Don't know for sure, but suspect the K&N was the reason for my mass sensor getting dirty although I didn't find anything on the inside of the SLP high flow lid. Can't tell much difference in power between the two filters anyway.

 

Holley Powershot

blue filter looks cool under my clear lid,good fitment,no gasket required.

 

no. it does not.

 

I got rid of the K&N for a Fram.

 

I use the Holley Powershot filter ....looks cool with the clear lid...I also have the K&N but won't use it....Does The Holley worlk better than the K&N??..how bout for people with the FTRA application??..........
