I just bought some Mobile 1 M-108 filters for my car and was shocked to see how small they are. I can't believe that a 3.5 V6 would have a filter this small, it looks like it should be on a moped or something. I was just wondering if the stock filters were similar in size. This will be my first oil change so I don't know how big they are.

 

I purchased K&N oil filter for mine. I was also shocked at the size. Yes, that's it. I checked out Fram & Nissan's filter to see if they were the same & they are.

Do a search. Subject has been discussed ad nauseum, and links given to filter ratings.

 

Yes me too. I use K&N also. When I saw how small is was (the HP-1008) I called K&N Technical. The Tech told me the HP-1006 is a little longer, a bit larger in diameter, but has the same pressure specs. It fits fine, and I've been using the HP-1006 with no issues. IMO, K&M oil filters are tops.

The Maxima filters are slightly larger. I use them (recommended by the dealer).

Use the M1-110 it is slightly larger with the same pressure valve. Mobil 1 filters are better than K&N because the use a synthetic fiber vs a paper element which is less likely to break down/ clog. They also have a higher filtering percentage vs K&N.

On pressure tests, however, M1's have been noted to sometimes cause a fairly large drop in pressure due to the restrictiveness of the filter. K&N's have been tested w/ almost no drop in pressure.

Also, K&N does use a synthetic media as well.

It's probably fine either way, but given the small size of the filter, and the fact I wanted to run extended drain intervals, I chose to go with the K&N 1006 to avoid any potential pressure problems, particularly on extended drain intervals.

I've used M1's in other cars though with good results - so like I said, it's probably okay either way. Purolate Pure One are also great filters too - very high filtering percentage, about the best out there, but same thing, sometimes cause a drop in pressure as well.

K&N does not use a synthetic filter element, unless they have just started VERY recently. It is a resin-impregnated paper element. Do you have a link that says it is synthetic, because if so, that is news to me. The tests I have all seen have confirmed that it is paper.

Want to learn about oil filters? Go to

http://theoildrop.server101.com/ubb/...?ubb=forum;f=6

those guys are serious...BTW, check out the thread "BOBISTHEOILGUY FILTER TESTS", it shows various filters tested...(Looked how the M1 dropped in pressure)...

 

What do you guys think about the Nissan filters? Think it would be okay to use that filter with synthetic oil?

 

The Nissan filters are perfectly fine, and a safe choice if you're unsure about which aftermarket filter to go with. After all, it's the one Infiniti recommends for the car.

Aftermarket filter sizes were discussed here: My first oil change! -- along with part numbers for different brand replacement filters, OEM size and the larger size.

Can any confirm whether the K&N part number for the larger filter size is 1006 or 1010? Then I can update that list and put a copy of it in the FAQ section.
