de-restricting air filters

[nozza89]

maybe a stupid question but how can you do this and how much does it cost, my mate mentioned it last night and said something about just drilling holes!!

Why would you want to de-restrict a standard filter anyway? Just get an IK if your not happy with the standard induction set up. Or get a panel filter which does the job of an IK without the effort of replacing the whole system.

You can drill holes in the air filter box underneith it, but that will only give you some noise of an IK, it won't do anything to the performance.

thanks i thort that would be the case

drilling will also destroy the box head shelding abilities too,

Drilling holes in the airbox will make it sound like an IK but is but silly imo, just buy an IK as said. Either way your not gonna get gains from it lol
