RALLIART Urethane Sport Air Filter is rated to increase 10-15hp over stock air filter. (increase 10-15hp over stock air filter?????)
Forget ambitious, its flat-out BS. You wouldn't get this increase running NO air filter. Also remember your power gains from such 'modification' (if it can be called that) are WAAAY up in the end of your rev range where you'll never even notice them except on a dyno... Which isn't an accurate representation of real-world scenarios anyway as you've got no 150km/h wind rushing past your IC and into your intake, no road gradient and no weather conditions.RALLIART Urethane Sport Air Filter is rated to increase 10-15hp over stock air filter.
