i have trouble beliving the # that this guy is providing..... you would need more then 8 hp to drop a quarter mile time by .35 seconds... sounds like a better launch or different conditions..... and raising the top speed by 4 mph highly doubt full, the drag at those speeds is tremendous, you need almost 3 times the horespower to go 150 then to go 100. and the drag gets higher and higher the faster you go. k&n airfilters are good. but he makes them out to seem almost super heroish....

 

This is a post by 3PUTT about the new K&N Air Filter includes pix of the new and old filters.

 

Well said ONAGER. Even in this day and age some people still believe that if they see it written somewhere it must be true. Points for you.

 

Yeah, their attorney finally saw their first response and said "WTF are you thinking. Why don't you just admit liability and buy everyone new engines."
If you used this filter I would have my engine internally inspected very thoroughly, especially if you like to run your car hard.

 

Those times and dyno numbers very well may be true, but ONAGER's response is also true and quite relevant. Dynos can deliver different readings on different days with the same engine. Also, how many runs were made with both filter scenarios?

As he said, 8 hp ain't gonna buy over 1/3rd of a second E.T.
