Yes, but the MSDS system is pricey at $109.
Plus it just puts the air filter in the engine compartment. I would think that
this configuration would pick up more heat than the stock set-up that is in the
air-stream from the right air-intake.
It looks like the system in the web page was made for about 1/2 the cost of the
MSDS system.
I guess it depends on if you have more time or money.
