the injectors are different on the CR arent they? maybe something cheaper might be developed for me, i can live in hope. And bigg are you sayin panel filters ruin performance cos dont jbs sell a green filter to go with their de-dpf? i have a k&n one in mine that i have had for years. i understand diesels dont need a lot of extra air like a full induction kit but surely the extra intake cant do it any harm?
