Replace stock air filter with KN ? Why ?
I have heard a lot of advertising regarding replacement of the stock air filter W/ KN. Tell me about your experience, before I decide to make a decision to go or not to go. Thank's THE BIG GUY ! ! :chevy :cheers:

Re: Replace stock air filter with KN ? Why ? (TheBigGuy)
The reasons are for power increase. The stock air box set up is very restrictive. The C5 likes to breathe!!! I'd suggest getting a whole new intake - my personal preference is the Donaldson Blackwing. Great flow and sound!!!! :cool:

K&N flows better, filters worse. You have to decide what is more important (although I know of nothing showing the poorer filtering caused engine problems down the road). Blackwing, BTW, flows better than stock paper, filters better then K&N (so I've been told).

Personally, I wouldn't replace just the air filter with a K&N, I've never seen an actual increase from just a filter change. However, if you replace the entire airbox with one of the many performace replacements out there, you can see a significant horsepower increase.

:nono:I dispute both of the posts above me--there is a SMALL decrease in filtering efficiency of K&N/oiled-cotton type filters, but it will not harm your car in any way--ignore that point.
As far as the lack of power increase, that, too, is not true. Any restriction you remove that allows the car to breathe better WILL provide an improvement in power--dyno testing proves it. That said, the power increase will not be as noticeable as removing the choker of a stock airbox these cars come with would.
End point--there's absolutely no reason not to swap to a K&N, you will feel a small improvement..but a new intake would be a much better solution, and provide a lot more HP. :cheers:

I went with the Exit 28 Motorsports filter. Replaces the stock air box and was $70. For me it was the obvious choice.

I was chirping the tires in each gear once I switched to a K&N in my '99 Coupe. Big difference in performance. Even more once I cut open the stock air box.
