this is getting confusing.. OP (Tam9n) IS using non oem i think
latest comment from jnmonaghan was just advising him where to get the info for correct oem
I've just been looking on autodoc for reference puposes and have found at least 3 different types, there's self levelling and non self levelling systems for a start, then there were 2 with distincly different end coil designs (unless that was just a case of 'picture may vary from actual product')
would definitely go back to that VIN plate and check what type yours needs
