European Air Box Question

Anyone know the part numbers for the European Air Boxes? and do they use the same size filters if I already have K&N'S?

Thanks for the Help......

"Row boxes" were good for 8rwhp on these? I seem to recall the European spec air boxes had a less restrictive air path resulting in the European spec vehicles to be rated at a slightly higher HP.

Same size filters for both the US-spec and ROW-spec air boxes. The ROW has no charcoal filters and a better and wider bell mouth MAF opening. Plug and play swap.

Did you remember the power increase for the ROW-spec air boxes? From my memory it was around 8rwhp, or almost 10HP at the engine. It was why European spec m156 vehicles were rated slightly higher.

Sounds about right. On a stock M156 there’s probably not a ton to be gained (even though the ROW boxes are a clear upgrade). I suspect as you start modding the engine and pushing it harder, the ROW boxes will really shine.
