Thanks John for explaining that!!
Dan it must be understood that every case may have a different result as we've seen in the past with other performance products. Any Filter will be on a case to case basis and will totally depend on your modifications, but it was great to get those numbers from John from a mostly bone stock 2000 SVT. If you would like to dyno the K&N and the same size AFE, I'd be glad to assist you in that, we do have a 9" filter you know...
REFUND, Stop being so cheap you dirty RAT
