Well, my local autozone was out of stock on my normal M1-104 Mobil 1 oil filter, so the guy talked me into trying the K&N Performance Gold oil filter instead (HP-1004). A little bit pricier than the Mobil 1 at $14 a pop, but I love this thing!

First it’s made of all metal, and right away you notice the 1” Wrench nut on top odf the filter for easy removal, and to snug it just a bit when installing it. Next, fire it up, and OMG the best oil pressure I have ever had at idle 55 PSI, hold the throttle to 2k and Bam instant 80PSI. I was very impressed. I checked out the K&N web page to see the micron numbers for such a good flowing filter, and sure enough filters to 10-20 microns in size. It also has a pressure release, and is spring loaded internally. My recommendation is a must try for anyone who cares enough to buy the very best for their 7.

Give me 2500 miles and I will re review the filter after I cut it open and check it out inside.

Here is an excerpt from K&N site.

“K&N Performance Gold Oil Filters for automotive and marine applications have been constructed from the ground up to satisfy the high performance needs of race car owners and drivers, as well as the average vehicle or boat owner who wants the very best oil filter available. The heavy-duty construction provides strength to reduce the possibility of bursts and helps reduce the risk of rock and stone damage. A Sturdy 1" wrench nut makes removal quick and easy The filter’s inner filter element traps contaminant as small as 10 to 20 microns in size. The solid construction allows for oil flow rates between 12-16 gpm (depending on filter size), and is unaffected by racing fuels”

wow $14 for an oil filter is really pricey. Think I'll stick with the OEM filters.

 

I agree $14 is a bit spendy for an oil filter, but the Mobil 1 filters usally run me $10 anyways. I have tried OEM oil filters, IMO they are far to restrictive, and lower my oil pressure to much. You may not notice this as much on a stock oil system though.

wow just re-read your post and 55 PSI @ idle is very very impressive, off the top of my head I think mine was like 35 or so.

 

that is not stock, I run a 80 PSI Oil Pressure relief valve, and a high flow oil pump. But that might be why I notice the higher flowing filters more. The mobil 1 was a steady 45-50 (idle) with my current setup, so the K&N seems to flow just a bit more pressure. And if my memory serves they are rated at about the same micron filtration.

 

I have been using the K&N for about 1.5 years now. Thankfully, they cost about $10 in my area.

I feel that it's the best filter I have used thus far.

Nice! I did not realize they have been on the market that long. Good to hear they are somewhat proven. This was the first time I had ever seen them at my Autozone (and I am weekly shopper ) maybe they just started to be a distrbutor for them.

yeah i definetly like the mobil 1 filter i get like 40-45 psi at idle (depending on temp) and am at 60 by 2000 rpm. my oil system is bone stock and i use 20w-50

 

i bought a K&N filter when i first got the car... 20 dollars canadian for an oil filter? after i started changing my oil monthly i switched to OEM

 

Mothly?? The poor enviroment! thats a bit extreme in my eyes.

 

if I changed my oil every 4000km (2500 miles) it would be monthly, at least.

 

Cool! I'll run out and buy one tomorrow, thanks

 

i change my oil every other week with castrol 20-50w
but i have a sponsorship from castrol.

 

Um, higher oil pressure (from the sensor) is not necessarily indicative of a better oil filter.  The higher oil pressure means the oil filter is MORE restritive (than the older unit).  This is probably due to the fact of the lower micron filtering element.

thats just what i was thinking ted

your getting more pressure cause its harder to puch the oil through the filter its not flowing any more but that nut does make removal simple

 

you guys get all "moody" over 14 bucks!!!???

Geeze!

For 55psi at idle, and still filter damn good... I think I will budget the extra 6 bucks



***EDIT***

Ah, just read Ted's post.. dammit.. that makes sense

OH well.....

 

yeah.

 

i posted above Ted, i was worried about that also, It filters to 10-20 Micron. As good as any filter on the market. My higher PSI is do in large part to my upgraded oil system, but if the specs say it does 10-20, and it still flows better. ... good enough for me.

 

I thought K&N bought fram filters and just rebadged them? Didnt somone write an article on this?

 

Not that I know of. I bought a Fram filter once (the cheap orange one.) Didn't even bother putting it on. Just went back in the store and returned it. Got a K&N filter instead. Tried it out, fairly happy with it. I paid $8-9 for my filter though. And the price shows, the oil filter seems well constructed.

I haven't tried many oil filters (don't even rake up enough miles!) but I would recommend OEM and K&N filters definitely.

 

If you go to advanced auto parts the same filter is 9.95... I noticed that the other day when I went to AZ, much more spensive!

 

Yeah, 10-20 microns is real TINY.  Majority of oil filters do most of their filtering only down to the 30-40 microns, so the K&N goes down another 50% smaller!

The physics of it is that restriction goes up (flow goes down) as filtration gets better.

The only way to get around it is to enlarge the filtration area (i.e. make the oil filter larger).

K&N doesn't make crap, so I'm not against their products.

Crap, that's CHEAP!
The Mobil1 synth oil filters from Las Vegas, NV AutoZone was $12!


-Ted

 

i use a fram oil filter still get some good oil pressure hehe but i can't really tell a difference in oil filter it used to have a mobil one i think can't remember
