Today i installed my new works air filter and wow i cound feel the difference.
i used Dll to see this difference the car is bone stock now with the filter added.
i did the test at the same road the same day and time here its the dyno graph!




it gained 10whp and 10ftlb of torque!

 

I put my stock tune and paper filter back in a couple of months back... it was really bad. When all i had was the hks drop in filter, I could feel the 10 hp right away then too.
