I had this same question. I bought the recharger kit for my SRT, but it looks bad. So I was wondering what if I got a K&N from eBay instead.
Anyone ever try this or have insight as if this would be bad/good to the engine?

I was looking for the same thing too a while back, but instead I just went with the AEM Dryflow Filter

Not to change the subject but I just bought the HKS drop in filter for the stock unit, how well does/will this product work? Any owners of this, or knowledge would be great. The reason I ask is because i always thought K&N made superior products and aparently others think other wise. My friend has an SC300 and he got the K&N drop in filter for his stock unit and it seems to work just fine? Any response to these claims of dirt on the t.b.? Why/how did it get there? Thanks

A K&N works so well because it does not filter as well lol. Yes contradicting but its true, heres why. The stock filter filters quite nicely but to do so, it requires the filtering media to be packed more densly so the little dust particles will be caught. The K&N works so well performance wise because its literally full of holes. I mean, a silk sock will probably trap more dirt than the K&N lol. Basically the K&N is just preventing the big stuff such as leaves and bugs from entering the engine, but the dust that can cause scratches on the cylinder walls and gunk buildup in the intake passes thru the K&N. So the question is are you willing to let your engine ingest more dust and dirt for the measly 2-3hp gain?
Hold the K&N filter up to a light and look thru it from one side to the other or inside to out. You will literally see specks and little holes all over the filter. Now do that with a factory filter and there will be zero holes. That's why I recommend the AEM Dryflow filter. It's packed pretty much as dense as a factory filter....BUUUT it's washable and requires no oil
The way around the restriction is to get a bigger filter. This only applies if you have an aftermarket intake. Stock intake box cannot fit a bigger filter. If you have a stock intake then I suggest you stick with a stock factory filter. If you have an aftermarket intake...lets say a K&N 4" tall filter will flow a good amount of air. Putting a similarly sized AEM filter will probably cause a 10% restriction in flow. Solution: get a 4.5" tall filter and problem is solved

Don't use it....lol
It doesn't trap dirt very well at all. I'd almost wager to say it's even worse than the K&N. It does perform well though since it's basically just a sponge filter that lets in a lot of whatever
The AFE dry filter is also a viable option. If I'd have to wager...I bet the AEM dryflow is made by AFE but just rebranded with an AEM label. AFE is a filter manufacturer, I don't think AEM actually manufactures those filters themselves.
