I still have my stock air filter and I have concerns about dust particle tolerances. The disposable, stock paper filters filter out the most stuff, so that means they let the least amount of dirt into the engine, but how much does this matter? I want my car to last a long time!

As for a filter choice, it doesn't seem worthwhile to do a new airbox, so I would just be looking at drop in filter replacements. I was thinking that I would do the velossatech ram air at the same time, so hopefully I would actually get a performance gain. I was thinking about a Green Filter or an ITG. If I do the ram air, would I want the filter end capped, or open? I am assuming capped..

It depends on where you live I suppose. I've run open throttlebody for a few hundred miles in my civic before haha.

The less contamination inside the motor, the better. Eventually you will get crap in there, I don't think it'll cause your motor to blow up at 100k miles but it'll accumulate stuff faster.

What was the situation there? Forget to put the filter back in?

Run that filter as well and I wash it way more often then I would any other filter because it is as easy as spray with a hose and setting it to dry. Forget about oiling filters, waste of time and money!

we were abusing the old motor before a swap haha.

IMO, the oil in a turbo charged engine has a hard enough life as is, don't make it worse by letting more dirt through your air filter. I'm pushing 360whp+ on a Motorcraft paper filter so it's really not a necessary "upgrade".

I remember @psilynt writing about this, care to chime in again?

edit : woah.... you typed your post as I was typing mine, I was just waiting for the 30 second timer to pass to post hahaha

Great minds think alike!

I've seen this debated on the diesel truck forums many times. Here what I've learned from personal experience.

I had a 2002 F250 with a 7.3 diesel. AT 73K miles I installed an AFE stage 2 open element, oiled gauze type filter. Just like a K&N. I ran the truck that way up to 213K miles. I changed the oil every 7K miles based on the regular oil analysis samples I had done at Blackstone Labs. The oil always came back in great shape. They even said that I could try going 8K miles if I wanted between intervals. I cleaned the filter once a year and the intake track was always clean and dust free. Now I don't live in the desert, but I do construction and some places are dusty. I would drive about 17K miles a year in all types of weather. Never had to have any motor work or turbo work performed and sold the truck running perfectly.

So, I don't hesitate to run an oiled gauze filter in anything I own and never had any problems, including ATVs.

Afe aren't oil gazed like k&n, they are actually a layered material and do a good job of filtering unlike k&n.

With that said I'm running an aem on my st. I would have stuck with paper, but I have an frpp snorkel and water and paper don't mix.

It depends on your driving situation. If you live on a gravel road or drive around in a lot of dusty areas, I'd leave the stock filter. I don't live on gravel so I enjoy the extra noises of the Green filter!!!

Makes me remember the other day, road crews were cutting control joints in new concrete and spitting all that dust into traffic! Not happy. That **** is hard on paint, and can't imagine what that'd do to the inside of your motor.

I can assure you that the filter that was in my kit was an oiled style filter. I know the difference.

That was also not the only vehicle I had many miles on and had oil analysis done.
