I have heard that when at the track some people remove their air filter completely. Is this true? Has anyone tried it? How much improvement could you expect without the filter vs. say a K&N filter?

Switch to a K&N or similar filter and you won't have to worry about it. The high flow are very unrestrictive so I don't think it will matter too much. Also, our cars aren't making tons of power to really make diff of open vs filter. Just my .02Let's flip a coin. Heads I get tail, Tails I get head. -

if you like scored cylinder walls run it without a filter, if you had a 8 second turbo car the filter might be a restriction that would cost a .10 but leave it on for the engines sake

Re: Track racing without filter?
I have run an assload of times with more then one car with no filter....
there are risks, yep, and the gains are not that great but ehh.... depends on your thoughts...
another thing that isn't so bad on 98+ cars, is just buy a new paper filter, ands just use it for track, only have it in when you are the track.Comment

Re: Track racing without filter?
In my experience, correct me if I'm wrong, filters are designed to draw power even stock ones. Taking the filter off is useless.Comment
