K&N Performance Gold Oil Filters

[Robroy]

Anyone that uses this kind of oil filters? And if so, what is the experience….:user:

I don't use it so I can't help you. I installed a regular oil filter this summer and I am sure you won't need such oil filter as the k&n on a normal 455.

Per, I don´t have any experience with such an oil filter too, but just some days ago I thought that it could be better for me to have a filter which catches the very fine particles from the oil. This thought struck me when I looked to the oil and recognized that it gets darker faster than before. You know that I changed to the oil with the Mathy-Additive and it seems as if this mixture still removes or dissolves old cacked-on particles from inside the engine. So I will change to a micro-particle-filter when I have to change it next year. Until now I don´t know what filters are best for me; perhaps it could be such a filter of K&N. I will inform myself within the coming months.

Therefore I´m strongly interested in experiences with such filters too and probably someone of you out there could recommend some of those micro-particle-filters (?).:user:

Rolf, I actually bought two of these during my visit in USA recently. They will come on at future oil changes so I can share the experience then.
I started this thread because I was curious if any other board member had used them or heard about them.
The only possible disadvantage I can see with using such a filter is that the oil pump will have to work a little harder to suck the oil through the filter which probably could result in a slightly lower oil pressure.

... probably, but you have a high enough pressure, Per, so that it will be no problem.
And if I would install such a filter I could rise the pressure a little b/c my oil pump is an adjustable one - no problem too.

On the other hand the filter might have a geater surface of the inner membrane than the normal filters so that the pressure would not lower. Do you have any information regarding this piont - greater filter membrane than normal ?

As far as the K&N I run one of those for my Buick Race engine. THey are great filters a bit expensive though. Just a thought here guys. If you are changing your oil filter in about 3,000 to 3500 miles I would figure any decent filter will do. The driving that we do with our Centurions is pretty much easy miles. Unless you race it like Adam and Nick. With mine and I tow with her I use Mobil 1 Filters and change the filter with the oil every 3,500 miles.

Not meaning to hyjack the thread; You want to see large oil filters check out this one I use for the racecar, its a K&N #5001. I also use Master Lube which holds an extra 2 1/2 quarts and is used as a pre-oiler and and also dumps the oil in the engine if pressure drops below 30 pounds. The oil pump is a Peterson external vaccum / oil pump and we installed oil line feeds that go directly to the main bearings from the oil galley along with feeding the block from the rear and front. Warmed up and screaming at the end of the 1/4 mile at 7,000 rpm's the oil pressure reads around 125 pounds.

Thanks, Rick,

for your input here and also for the more of information regarding your special race equipment !

I have a Purolator Premium Plus L20033 in my car; it seems to be not bad - perhaps good enough, but I´ll continue thinking about and gathering infos.
So thanks again for yours, Rick !

I found this on their homepage, seems that the oil pressure won’t be affected…..
High-Flow Rate
Our oil filters use resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process. http://www.knfilters.com/oilfilter.htm

This filter is probably, as have been pointed out, an overkill if you don’t race but 11 dollars is what I pay in Sweden for a ordinary AC-filter, so I thought why don’t spend that money on a good quality filter instead now that I have the chance. I also figured that even the tiniest particles in the oil could give problems with the lifters, especially on car than stands still for long periods like mine.

Thanks for posting all the oil filter info Rick!

I use the K&N Gold in my 64 Thunderbird and in my 87 Fiero.
On the 390 in the Thunderbird I didn´t recognize any difference.
But my T-Bird engine is in nearly "new" condition. It has 30000 miles on since 64.
The Fiero engine is a performance build up 2.8 with a HV Oil pump.
On this engine I used a standard oil filter for the first 500 miles after the rebuild.
Then I changed oil and filter and that reduced the oil preasure about 3-5 psi (depending on the oil temp.) The Fieros oil preasure was at 75 to 80 psi, and is at 70 psi now.
But I don´t think that this is a bd sign because K&N says that their oil filters flow better than the standard filters. more flow => lower preasure.
My opinion is that you should use the filter only on healthy or rebuild engines with good oil preasure. If you engine is woren out a little bit you should use a the normal filter.
Or you swap to a HV pump. That will work fine. And aspecially on a Buick 455 it´s never a mistake to have a look at the oiling system. The increased oil volume and preasure will keep your mains live longer.
Hope that help a little bit

Thanks, Per, for the extra info about the K&N Gold filter.

Thanks, Austrian455, for posting your experiences.

For me it gets clearer now:
- good for normal driving conditions are filters of K&N, Mobil 1, Purolator and Wix and those which are built in a similar way
- filters for very small particles often cause lower oil flow and may require higher oil pressure
- some filters are built especially for special use (racing, towing, small particles, ...)
- special filters have special prices

So far I would take the Mobil 1 filter for my engine next time to get small particles out of the oil and see how it works and then the next time I would change back to what I have now - a Purolator Premium Plus which is good enough for my driving conditions, strong enough, without specialities and cheap also.

Thanks again for all your help Per, Rick and Austrian455 !
