OK, I changed my oil today and before I did my friend suggested I use a K20 oil filter on my b16 motor becuase it's a smaller filter, and it builds up oil pressure faster or something...so I got one and after the oil change vtec seems to hit harder...is this true or a myth.? I'd really like to get this traightened out...

So the question is...Do smaller oil filters help build up oil pressure? and if not what advantages would they pose?

 

never heard of this befor?....but is this thrue?

Heard of this before, but never tried it.

 

i bought a bunch of them last time i viisted Type One.

So does it work? What's your feedback?

 

The only thing I can see with this, is that if the filter is indeed smaller, then your capacity will also be smaller, hence more pressure. Now whether any of this is true I don't know, and as for VTEC "hitting" harder that shouldn't be the case, but again...Who knows??

Honda isn't selling the larger ones anymore. They're making the switch to the smaller oil filters now.

 

brings your fuel pressure up about 5 psi i believe. they are the newer civic and rsx filters.

So we have no choice but to upgrade to RSX/EP filters? Sweet, Honda approved.

 

i hear that it does yeild higher oil pressure...tested it on a friends car with a mech oil pressure guage...
seems to work, works well, running them in my car

Sucks, doesn't it?

 

i dont think it has to do with the size just the way the filter works. yes the smaller honda ones build more oil pressure but the reason your vtec "hit harder" probably has more to do with the new oil rather than the filter.

I used to do this on my turbo integra for that reason. Nothing ever went wrong, but I never measured the oil pres. increase.

 

which is also the reason why people in japan has switched over to the smaller HAMP filters as well

 

Works, Dr. Charles from Area 51 told me about it back in the day and have been doing it on my B18C ever since. The S2000, and the NSX both use the K20 filter. ;}

 

I heard some people used WRX oil filters on B series engines since they were larger and allowed the oil to cool more. I'd imagine either way the difference is small, although the smaller one would shave off an ounce or two

The older Mitsubishi Montero filter also works.

 

The volume that the filter holds will not have an effect on pressure - not saying that the K20 filter doesn't increase pressure, but it is not an effect of volume. It is an effect of area:

Pressure = Force/area

If you input the same force (from oil pump) but reduce the area filtered, you can see that the pressure would increase. Take a number and divide it by a smaller and smaller number and you will see that the net result is an increase.

Don't you just love physics?

Oh, and that thing about larger=more cooling is dead nuts on! Minute, but it does increase cooling.

 

so have we come to an agreement yet smaller filters = , if so a k20 filters going on my turbo d16.

 

also larger filters =

 

Filter schmilter.

The only way a filter could increase your oil pressure is by restricting flow, but then your filter bypass should open up, and defeat the filter building pressure...

The thing in the engine that determines oil pressure is bearing tolerances. Tighter tolerances=more pressure. That's all.

So, more restriction by a smaller filter would equal more pressure, but less oil flow.

 

restricted flow will increase pressure before the filter but decreased flow of the smaller filters will increase pressure of the entire system because it will make you oil pump more effecient. I vote for the smaller filter!

No, the pump does not make oil pressure. All the pump does is simply supply oil flow through the engine. A high flow pump may "make" more pressure, but only because it flows more oil through the engine, where the crank and cam bearings turn the oil flow into pressure.

Too much flow or pressure will, like the oil filter bypass, activate the oil pump bypass to reduce flow, therefore reducing oil pressure.

The smaller filter will be nothing but a restriction. Honda chose a specific filter for a specific engine for a reason.

But hey, if you want to use a smaller filter, and risk eating an engine due to decreased oil flow, be my guest.

Trust me, I'm not talking BS here.
