cotten

Evening folks, While removing the airbox today i've got my hands covered in what can only described as green "dust". Having a closer look its all over the MAF exit end, the rubber/plastic feed pipe that goes off down to the rear of the engine. Now i've cleaned it all up the best i can...

Hi I was just wondering what peoples opinions are of changing the standard air filter with say a green cotton version? I have my 140 diesel remapped to 185 so would it be worth purchasing? or are they over-rated? Cheers Clarke
