Looks like you are using cheap oil! :party-smiley-004:

Snake oil......

Hey Rooster, looks like you got the short HP 3002 filter, $12 and change. The larger HP 6002 is a few bucks more.

The taller filter will provide zero benefit. The K&N 3002 is a huge upgrade and designed (pleat count and height wise) for a V-8. Larger filter just adds oil volume, which isn't always a good thing. A longer filter does not equate to better filtration for those following this.

Just to kick the can around, why wouldn't more volume be a good thing?

I would like to hear this as well.

And what do the experts recommend for minimum flow for an oil filter? To get better filtration you have to give up flow.

Mine is long! and I Think its better.
Big too :food-smiley-007:

Filtration and flow has a fine balance to it especially depending on the engine app - you can not have 100 % filtration to maintain 100 % flow just as you can not have 100 % unrestricted flow to maintain 100 % filtration. A happy balance point is between the 2. You can not have the complete best of one without hurting the other.

I would also be interested in knowing why more oil system volume may not be a good thing. Obviously a longer filter isn't going to equate to better filtration. 10 micron filtration is what it is no matter how big the filter is. Seems to me by doubling the filtration area you are going to have a higher overall flow rate. Remember most of these engines on here are running high volume pumps and spinning over 5,000 RPM's.

Exactly. I would think that different engines will have different demands for flow. But, what is generally considered "adequate" flow? Is 12 gpm enough for a stock 502? For a 800hp supercharged 540?
