Good work - I didn't fancy the intake valve cleaning, so got BMW to do it. I just knew I'd screw something up, and it'd have taken me forever. My car is currently with BMW having the walnut shell blasting done.
They've given me a nice 320i X-Drive as a courtesy car though, which is pretty neat.
So what's the difference between the D4 and D6? I'm not sure which would be best for my climate, and if the thicker one would cause more drag and lower mpg and whp?
