"Can't belive the improvment in my LS1 performance!! Cheapest way to go for extra HorsePower. Don't know about improvement in fuel MPG...too busy having fun with the extra power! Best thing you can do for your car or truck." —Eddie M from Shawnee, OK bought a K&N Air Filters for a 2004 Chevy Corvette.
"OK" —Keith J from Owens Cross Roads, AL bought a K&N Air Filters for a 2004 Chevy Corvette.
"The two metal tabs that hold the enclosure to the Corvette's filter housing are a bear to do, still haven't gotten them back in place. Will have to go on the internet to try to find out how to get those back in place after the instructions said to remove them don't do it. My big hands aren't able to go down in between that and the hood to try to get them to hook back up. They need to slide and hook in the bottom and you'll need a pair of pliers. Has to be an easier way than what K&N has given in their instructions." —Bob W from Albuquerque, NM bought a K&N Air Filters for a 2004 Chevy Corvette.
"I have a K&N Air Filter in the family car and in my Corvette.They arre working just fine. Gas mileage will be determinedwhen the daughter lets me drive my vette and the wifelets me drive the family car. :)Have a good day..." —Barry L from New Port Richey, FL bought a K&N Air Filters for a 2004 Chevy Corvette.
