The SW filter they use is nearly 7 times thicker at 14.07mm. You say cotton gauze catches more dirt and sand then foam, then why does almost everyone in motocross use foam (which is one one the dirtiest sports out there)? You need to stop hating and get of your pedastole.

 

I am not defending anyone. I am not advising foam filters worse than cotton gauze. What I am saying is that the HKS Super Mega flow filter that comes with the RS kit does NOT filter sand. I found sand inside my MAF sensor and some sandblasting on my compressor wheel.

Because of this I now run an Apexi Power Intake filter which was tested in Japan about 3 or 4 years ago and proven to be the best JDM filter at that time. The K&N type filter was second in that test, if I remember correctly.

I dont think anyone has any first hand testing or experience with sand infiltration problems with the Secret Weapon filter, so I dont think they were picking on your filter.

an oiled foam filter is different than a dry foam filter

 

How is it "different" in regard to filtration and flow properties?

 

You could just get an Outwears prefilter. Works good for me.

 

True ! Good idea

 

Becuase when you oil it the dirt sticks to the oil

 

Because foam filters are cheap and you can throw them away when they get dirty

 

No it's becuase they filter better.
