I don't think it would be warranted under the Magnusson-Moss Act. The act you are referencing only applies if the aftermarket part used is unrelated to the failure. For example, they can't void your warranty on lets say your transmission because you have a cold air intake. But if you have a cold air intake and your airflow sensor fails, they could argue that its not warranted.

Likewise if you have an aftermarket oil filter and it bursts causing oil loss and engine damage, then the part you used actually was the cause of the damage and probably wouldn't be warranted. That being said, I doubt a high quality oil filter like some of the ones mentioned would actually burst but it does happen on occasion.

Some owners are using the K&N HP-1010 which is longer that the HP-1008 but seems to fit fine. You should be able to find these for $9.00 on the web.

Purolator PureOne. The one for a '06 Honda Ridgeline is the extended capacity version of ours (It's a little longer). Should be $6 at your local autoparts store Should be gold textured finish that makes it so easy to get off i haven't even had to use a wrench on it (and yes it was put on tight all the tens of of oil changes I've done). Excellent Filter that is superior to the Mobil one (Car Craft or Hot Rod did oil tests and flow tests can't remember witch mag it was). Saves you money to buy some good RL or Motul 300v oil.

I'm using hte Mobil1 M1-110 instead of the Mobil1 M1-108 - same idea.

Mobil1 filters are the exact same as the K&N filters internally. The only difference is the white paint, higher price tag, and the welded on nut on the bottom of K&N. :)

WIX Oil FIlter
 

Hmm, I was inform that the WIX part no. 51358 is compatible with the 370Z according to the Amsoil web site. Does the WIX oil filter 51356 filter down to the typical 12 microns? Is their any change in the oil flow using the larger WIX filter?

Really? I didn't know that thet are the same...I'm using K&N, next time I go to the store I'm going to check the price difference.

Sorry to bring back an old post but if that's true I think others may be interested.

At least with K&N it is not necessary to use a chain wrench to remove the thing and get covered in oil when the casing splits !

I use the K&N HP 1010. Just walk into you friendly neighborhood parts store and ask for a filter for a 2009 Nissan GTR. The filter is about an inch longer than the stock 370Z filter.

I find it so funny that some people argue that paying $14 for an oil filter is stupid. I paid nearly $40,000 for my 2009 370Z, brand new. To me, the argument between using a $6 cheapie Fram filter and a $14 K&N is a moot point. I save money on filters and oil on my wife's Trailblazer so i can put only the best in my Z.

Advanced Auto Parts is running an oil change special, 5 quarts of Castrol Edge and a K&N filter of your choice for $29.99. Normally that would cost $55.

From the UAO reports it seems a decent oil.

yup, I still got 8 quarts of Valvoline left from their last special @ $26.99

I am still worried about aftermarket oil filter since they could change the oil pressure and flow characteristics. Also consider this, Nissan uses different filters for the same VQ motor, yet aftermarket has a one size fits all. THere must be a reason why Nissan did it. Is it so much filtering capability or is it more pressure drop? Usually a bigger filter will drop your pressure slightly.

Does Nissan have a special oil filter similar to TRD? I know I can buy a TRD filter for my Toyota that is thicker and have a metal casing instead of paper. Does Nissan sell a briefer version of the filter that is meant for the Z, not other cars?

With all that said, I am running a K&N because it was on special with the Valvoline two months back :)

I was looking at that oil & filter deal over this past weekend and passed on it.

From what I read in the very small print, was that you have to pay extra if the filter that you need costs over $6.95. I think a K&N filter for my 370Z was $11 or $12, so I would have had to pay the difference.

I ended up going with Mobil1 oil & a different filter.

Just because WalMart sells Fram filters means that they're junk? That's a pretty broad statement to make with nothing to back it up.

Nice, I'll check that out next time.

It allowed filters up to $14 for the Edge/K&N deal. I bought a HP-1010.
