Is a K&N REALLY better than a cheap fram filter? I don't think so.
 

I took my car to the dyno a while back and did a few runs. I put down 206whp stock ( only had z-tube which I doubt does anything ) with a cheap fram air filter. I took the filter off and did another run and to my surprise I actually LOST 5whp. I would guess that the loss was more due to heat soak than anything else ( it was a consecutive run ) but that also shows me that aparently the cheap *** fram filter really isn't that bad at all.

So what's the point of getting a K&N? Thoughts?

the fact that its actually a better filter.

The main benefit is that you save money in the long run because you can reuse them. they won't give you more hp and they do not filter as well as paper filters. I've used k&n's in the past with no problems at all. However, I plan on keeping my G for a while, so prefer the extra protection of paper filters.

next time run k&n first then the fram filter and see if you get the same results. there could be many reasons why a 5 hp was lost but just doing a single pull dyno on each doesnt prove anything.

i think the hp shouldnt have changed but the air flow would have

Actually it was spread across 5 runs.. 3 with the filter and 2 without. All of them were within 3-5whp.

I wouldn't use an oiled filter with a car that has a MAF sensor if you can avoid it. The oil ends up over time screwing up the MAF, and all you have to do is clean it but still it's a PITA.

Also the oiled filter doesn't trap the small particulate like a good quality dry filter will.

Why do you think AEM moved to dry filters?

IMHO, running the dyno test with the fram and then no filter at all doesn't validate or invalidate the K&N unit at all.

Why not? Do you think a K&N will be less restrictive than no filter at all? lol.

What do you think would happen if you ran a K&N and then no filter? Would those results invalidate your fram?

Why would they? The point was to see if my fram was a restriction...if it's not then I can assume that a K&N won't make it any better...it can only make it worse or stay the same.

How can you come to those conclusions when the K&N was nowhere near this test?

The question is "why won't it invalidate".

i must of read the first post wrong. so how does the K&N come into play if you never tested it?

Because he uses some sort of idiot logic. JWT popcharger, and call it done.

Dude was basically saying that he was hungry so he ate RICE. It filled him up, so in conclusion a more balanced diet isnt necessary.

Idiotic? You'd be the only idiot to think that a K&N would flow better than NO filter at all. The point of this topic was to wonder the point of going with a K&N. I tried a cheap fram filter and then I tried ZERO filter ( which happens to be the best flowing filter ). If the Fram made aprox. the same power...then how do you expect the K&N to do better? Or is the K&N a magical filter that happens to flow better than NO FILTER AT ALL? It's called common sense ( or lack of in your case )......:rolleyes:
