Apexi knows whats up. So taking into consideration the results of that test, has anyone ever considered buying one of these----->http://cgi.ebay.com/ebaymotors/APEXI...Q5fAccessories

I know most people run the K&N drop ins, but this is a dry type filter. It seems like this apexi would be a good drop in considering the results from that test, if they use the same style on their drop ins as they do on their cones filters then this should be one of the better drop ins.

 

do it. let us know how much hp u gained

 

this info is over 10 years old can it still be relevant maybe companies changed there products and made them more efficient theses test need to be redone

 

You don't really gain hp from a drop in filter. If anything it may be 1-2 hp but nothing noticeable. this brand of filter appears to have filtered better than all the others so it seems like this would be the better investment, but I havent heard of any reviews on this filter.
