I agree with these guys. We used to run the cone looking K&N through the pits and then take it off in the staging lanes. If you run a restrictor plate and ALSO run the filter you will notice the car gets kind of slobbery even at part throttle, But filter alone is worth maybe a hundredth or two. IF you run one and win, make sure you pop it back on before heading to the winners circle. I was not paid because the filter was not actually on the car. Sticker yes, product no. Spent several minutes on the phone with the contingency guy from K&N and he was afraid of getting in trouble if he let it ride... The rules, are the rules...
