Ok, so tonight I put in the new air intake in preparation for the S1 upgrade. (ended up getting a 100,000 BTU propane heater for my garage

)
I *think* I did everything right, but I had a hell of a time getting it in there... I went with the K&N FIPK... When I accelerate it makes kind of like a hollow sucking sound then when I let off the gas I get a "psssh". Thats how it should be, right?
Got the battery swapped out too. Plugs and wires will be later this weekend. Waiting for the S1 to arrive...
