My air filters just came! Great shipping speed from Performance Nissan at www.mynismo.com (aka www.performancenissanparts.com)

I am right at 50k miles with my HR, so I thought I'd go ahead and replace my air filters. Filters look of good quality, nothing beats OEM stuff.

The filters on the left were red when I bought the car.

 

.... lolz.

You actually used a scissor to remove the plastic?

 

actually that was to remove the tape on the boxes.. the plastic you could just tear it open

 

What do you do, drive around behind coal trucks? Several months ago, the original air filter on my '00 Silverado (with about the same mileage) looked almost like the new ones you just got.

 

i daily drive about 90 miles

 

how much were those shipped

 

about $40

 

I suspect new Frams from Walmart would be just as clean, and probably cost about half as much.

 

I could have never waited that long to change my filter

 

I went with K&N washable filters (370Z). About $110/2. Wash them every 10,000 miles. They will last forever.

 

I just got a set of Napa "GOLD" air filters for my '08 @$13 for the pair, during a 2-for-1 sale. Many auto parts stores will also have the Purolator filters for $12/each.

 

They might last forever, but the suck as filters. I installed one on my E30 M3 some years ago, and after a few thousand miles had to take apart some of the intake tract to replace a gasket. I noticed the entire intake (AFM, all the piping, plenum, and 4 throttles) were coated with oily, sticky grit. I had to remove everything from the head outwards to clean out the grit (mostly fine sand), which was a 6-hour task. The car had 30K miles, and had never had that issue with the OEM paper filter, and never had it since (50K more miles). All the other K&N claims (better flow, straightening the airflow, etc.) are nothing but pure marketing BS. I do have a set of oiled foam filters on one of my Alfa Romeo Spider's, and those work great.

 

How can you **** up the cleaning of an air filter?

Way to keep it OEM

 

cool story bro

you can sport the napa filters.. i keep all original stuff in my car

 

What do you mean? My problem with the K&N had nothing to do with cleaning/re-oiling the filter, it was about all the grit that blew thru the filter like it wasn't even there. Piston rings and valve guides don't last long with that sort of grit being sucked into the engine.

 

Sounds like a case of bad luck, My K&Ns have been in the Z for 50k or so miles, and my intakes all the way to the head are squeaky clean. Maybe I got lucky? I too clean and re oil them about once every 10k miles. My oil analysis comes back great on 3k mile OCIs as well so I'm fairly confident they're doing their job...

 

I did a Google search back when I had the problem, and there were 100's of hits citing the same problem with dirty intake tracts, as well as damaged AFM's/MAF's. Considering the K&N's offer no (not even a tiny) performance advantage, there's no reason not to stick with OEM paper filter panels. Granted, I'm in a somewhat gritty environment, as Florida is a sandy place, but that's grit of a large size compared to most, so if that gets through the filter, one can guess everything else will, too.

 

Really!

I haven't been strucken with a bad K&N! I've had mines on for 15k in Haywaii which Has the richest soil...it's like everywhere wash your car and the wind blows there's a sheen of red over your car. That's how thick the air is here on some days...it's fine really fine though so I'll give you that...

Well document the status of the stockers.
