I'm no mechanic, but shouldn't that be expected? You are increasing the air flow, so the ECU would adjust and increase gas to maintain the proper air/fuel mixture. Or maybe I'm completely wrong.. ha ha

my mileage has gone up with the Amsoil filter. I was able to get to 28.8 for 15 miles until I decided that gas was so cheap I could use up a few gallons my long term long will tell for sure.

I would reset your ECU by pulling the fuse or disconnecting your battery for 30 minutes.

Thanks for the correction, but can you explain? From my understanding, if the ECU does not compensate by adding fuel to maintain the proper mixture ratio, then you would be running lean. Am I confused?

I seriously doubt the filter is the biggest restriction. I also know for a fact K&N does not filter as well as any OEM filter because the OEM filter protects the manufacturer from replacing your engine. If the K&N filter is defective in any way, they'll replace the filter, but not your blown engine. Just something to think about when evaluating aftermarket parts of any kind - what will they replace if their piece is bad and toasts your engine? Few, if any, will replace your engine, they'll only replace their defective part. Manufacturers don't get this luxury as they are responsible for the entire car, so their solutions tend to be a lot more conservative.

Leave it to Lobuxracer to hit you with some real world knowledge. Thanks man. I always respect your input.
Still, how much damage could a K&N filter really cause to an engine if properly maintained?

is this filter from K&N come with oil spray bottle to cover it every 4k-5k miles? if so that may causes problem. I read from another forum whose members used K&N filter, they complained that oil had dripped down and covered the MAC reading of the air box causing some problem.
