so i had a set of 440cc injectors brand new and there duel spray pattern tipped and i sold them to my buddy that has a 2nd gen tsi,The thing is hes claiming these injectors are shorter then the ones that came out the car and says they wont work.So my question is can you swap 1st gen and 2nd gen injectors between the two cars?I dont get why these are any different I know for a fact there the 440cc dsm injectors but why are they different?
