Series 1 Or 2?

[stuartlaw_78]

Hi all,

This might sound like a stupid question to some but how can you tell the difference between a series 1 motor and a series 2 motor (R33 - RB25DET)????

I was told by someone that the air intake pipes take a different path... Ya??

PS.... just by looking at it??
