I think someone looked at that...

 

I think in general the aftermarket filters flow more, the problem isnt that though.

 

Its just some let more particles thru.

I have in the past run K and N and the oil did find its way into the throttle body. All Hp builds use after market so is 1 better than another ??

I have been told by many that paper OEM is fine unless you have a build and need the flow. HKS is less expensive than paper and a friend in LA just dropped them in.

I still like the topic a few weeks ago about modifying a stock air box with a 3 or 4 inch inlet tube.

Keep the paper until you go with a larger build. If your stock or just a tune, not worth it. Fbo you will probably want to go with something like gotboost cause he's using green filters which are better than most filters.

How do you folks feel about using K&N and simply replacing them every 10-15k? Meaning instead of cleaning and re-oiling.
From the Factory, do the K&Ns flow and protect better than paper?

I’ve tried the HKS and the intake and blow off sounds much better, but I’m worried about the actual filtration.......

NOTHING protects better than paper filters.  Period.

 

The aftermarket filters are there to FLOW better, but they do not provide the filtration.  The only filters that come even CLOSE are the Green filters with a prefilter - and even they don't filter as well as paper.

 

If you're worried about filtration, stick to OEM.

My HKS Green filters let "shit-tons" of particles through. My silicone levels in my oil samples were really high. Switched back to KnN conical filters which I lightly oiled and silicone levels went back to normal (almost 0)

HKS greens are terrible for filtration.

 

The ones that I'm referring to above are the ones that gotboost tested first - I think it's a USA brand Green Filter USA.  It's similar to a K&N but with a much higher density cotton I believe.

The green conical filters Dave (Gotboost) offers I hear are really good. They're on my "to buy" list. Anything Dave offers or makes is top quality stuff.
