But the E15ET is E-W? For the 120Y you need a N-S motor?
Tom pretty much explained it. Another advantage of blow through is PSsshhhhh!
though I am not installing one just yet. If you have any more questions about
blow through I *should* be able to answer them! :)
Blow through is much more expensive, but I'm hoping it has good advantages over
suck through. I've only ever seen one blow through L-series 1600 however I've
seen probably over 10 suck through L series 1600. I think your choice comes
down to the cost/difficulty. In my case I was lucky to pick up the blow through
kit.
