K&N vs. Holley I know its a dumb question but I have a K&N that a friend gave me and a Holley Powershot air filter that came in the car when I bought it both sitting in the garage. Which one do you think I should use?

Unless you don't like to clean it...but at the same time cleaning your oiled filter lets you keep it almost forever, instead of buying papers every time it gets dirty.

I've read that the paper filters do a better job of filtering the air. There's not a hp gain by going to a $50 K&N either. Even though I've had a K&N on every vehicle prior to this T/A, I'm sticking with the paper filters now.

I've run both the K&N and the Holley. Never noticed a difference except the Holley looks to have been produced better. The edges areound the filter itself are very crisp where the K&N edges are in to the filter. Tough to explaing.
Just do not oil the top of the filter and they will work great

I saw that display at a muffler shop. While it is impressive, the bottom line is does it equate to more hp. I don't think anyone has proven that a K&N is worth much on a dyno. If so, it would be a REAL small gain. The question is: Is an undetectable gain worth more junk getting into your motor. Oil analysis has shown that a K&N lets more contaminants into your motor. Also, some of the fastest cars on this site run paper filters.

There are pleated filters that filter better & flow better than K&N. Don't know why the discussion is always K&N vs paper. I wouldn't use either. Then someone will jump in with, "oh, I use a hydrostatic...blah, blah, blah & it's the best." Using a higher flowing filter will either increase power or VE. Either is a good reason to increase air flow or decrease the air restriction. Show me where the UOA indicates how much dirt it takes to negatively effect an engine or how changing the oil more often may reduce the effects of the increased amount of dirt. I also saw the paper test done on BITOG. This is LS1 Tech where guys run their engines to 7000 + RPMS & we're talking about the effects of a little dirt? Come on.
Do what you want...if you don't care about a little extra dirt, it doesn't bother me. 
I choose to error on the side of caution, and give up the whole .25 hp. To each his own.

I stick with paper. Less dirt will pass though, as many have said. Also, I don't like to be bothered with oiling a filter, plus just a little too much oil on the filter can = gummed up MAF wires. Then you have deal with cleaning the wires. Too much potential for problems with too little to be gained.
