I just resently got a Bonez intake filter. The only problum is that it is a 4 inch. Are there adaptors out there that i could get for my S5 N/A so that the 4" filter will fit my 3" MAF?

 

If your car is an S5 then you can buy a 3" to 4" or 3.5" to 4" might be able to get tight enough to silicone coupler that you just get two clamps and tighten down on each end. If you If your car is an S4 then you need to pick up the MAF adapter from HKS so you can make a 3" lip on it to connect a coupler too.
